Top Ten Tips for Business Data Cabling – Part 1

11 Aug 2018

structured cabling, cable installation,cablingA business cabling project can be a challenge to properly design, install, and accomplish on schedule. The key to success is finding an experienced team that will provide structured cabling services of high quality. Ask for references from companies that worked with them before and had a similar project. The following discusses the top ten tips for business data cabling to help you prepare for your company’s project.



Avoid Electrical Cables


Consisting of unshielded twisted pairs of wire inside, data cabling generates a magnetic field needed to allow it to function properly. Unfortunately, its unshielded feature means it’s unprotected from the magnetic field produced by electrical cables. As a result, data cabling should not be installed along side electrical cables.



Cable Management


Cable management is essential for a properly working network. It eases both maintenance and expansion. Although buying racks and other management tools are additional costs, they make revisions, addition, and replacement easier. Follow standard structured cabling best practices for labeling and color coding cables to promote efficiency.



Data and Voice Together


With the ascendance of VoIP telephone and Cloud PBX systems, along with the reduction of the cost of cables, companies are increasingly running both internal phone and data transmissions over the same network. However, this should be in conjunction with maintaining a single external phone line at the point of entrance. This safeguards an organization’s telecommunications capability even if internet is unavailable.



Interference Should Be Avoided


Similar to the problem presented by electrical cables, data cabling should not be installed near motors, fluorescent lighting, and any device that generates electrical or magnetic interference.



Length Limitations


The standard limitation for a length of cable is approximately 90 meters (roughly 295 ft.). There are specific instances and types of cable where the length can be longer or shorter, but that is on a case by case basis.


Part 2 will discuss Maintaining Standards, Planning Well, Respecting Regulations, Staying Up-to-Date, and Testing Infrastructure.

Typical Installation Mistakes of Network Cabling – Part 1

25 Jul 2018

structured cabling,Network Cabling,Washinton DCEvery cabling professional is aware that installing a network often poses challenges. As errors may result in long-term problems and high costs, it is important to avoid them by following standard. The following are several of the most typical installation mistakes of network cabling. Rely on experienced and expert cabling professionals to get the best results.



Bad Planning


Good planning always considers the future. Cabling technology that is already out-dated should be avoided. The equipment chosen should satisfy current requirements and those of the next five years. Although they are more expensive, purchasing high-quality cables and peripheral equipment helps meet future needs. Being knowledgeable about the organization’s facility and business requirements is also crucial to the project. Preparing well in advance will lead to greater efficiency and less expenses.



Electrical Alongside


One of the important rules is not running data cables in a position that is parallel to electrical wiring. Many network cables are made of twisted pairs, wiring which has two conductors twisted together for cancelling external electromagnetic interference, in order to prevent cables from affecting each other.  As a byproduct, they generate a magnetic field from the low voltage running through their wires. If network cables are laid next to electric cables, there is a chance that the cables’ magnetic fields will be interrupted, leading to substandard signal quality or a slow network.



Exceeding Distance


The majority of cabling professionals are well aware of the maximum distance limits of unshielded twisted pair (UTP) cabling up to 1 Gbps is 300 feet. When cables are run for 10 Gbps to 40 Gbps deployments, always be aware of the recommended distance limits that are imposed on the specific type of cable being used. To illustrate, when 10 Gbps is being carried the maximum of 300 feet over twisted pair cabling,  it will be necessary to use CAT 6A or better cabling.

Office Cabling for Performance and Efficiency – Part 2

31 May 2018

office cabling, network , data cablingAs discussed in Part 1, office space has become very valuable and costly in many cities. Some companies will need to implement space optimization, and designing their structured cabling network is a good place to start. Part 2 will discuss Cabling System Performance and Densification of Networks.



Cabling System Performance


The TIA 568 standard sets the limit for runs of copper cable to 90 meters (295 feet) from floor distributor to workstations. Exceeding this length will cause greater signal losses or insertion loss and delay limitations due to the Ethernet protocol, which can decrease the performance of the network.


An expansive floor size with a proper number of floor distributors will oftentimes result in cables longer than 90 meters and greater insertion losses. Moreover, short cable runs are affected by crosstalk and return loss.


Due to the increasing implementation of 2.5, 5G, and 10G Ethernet, along with the newest high performance WAP (wireless access points), it is crucial to install a category cable, such as CAT6A, capable of handling higher bandwidth demands in the future.



Densification of Networks


Horizontal distributor optimization inside the equipment room will result in increased floor space and improved network densification. The optimization of floor distributors can improve the usage of LAN Ethernet switches, minimizing intra-building backbone runs. Implementing optimized distributor placement will ease the management of the network and increase reliability.


The use of fiber and copper panels with higher port density should also be considered by network managers. One way to gauge design efficiency is to calculate the number of ports per unit of rack space. This assessment will result in the optimization of rack space, decreasing racks and maximizing floor space.


Using wall-mounted panels for terminating cables and easing their management should also be considered. This will also ensure the prioritization of LAN equipment and fiber panels for rack space. This method suits companies who desire the convergence of building applications and IP networks.

Basics and Benefits of Zone Cabling – Part 2

14 Dec 2017

network cabling,cat6 cableAs mentioned in Part 1, zone cabling designs provide benefits in materials savings, decreased installation times, and easier MACs (moves, adds, and changes). Part 2 will continue discussing the basics and benefits of zone cabling.



Designs


Experts recommend CAT 5e and 6 UTP (unshielded twisted pair) zone cabling topology with a connecting block system within the ZE (zone enclosure). This configuration will render unnecessary the stocking of factory pre-terminated and tested interconnect cords for connections in the ZE, simplifying cable management through the elimination of cable slack.


Please note that CAT 6A UTP media is not recommended for zone cabling due to reasons involving performance and flexibility. UTP cabling is vulnerable to crosstalk in particular installation scenarios. In addition, it is not the best media for supporting remote power applications with loads of 30W or more. Because CAT 6A UTP zone deployment is dependent on modular connections inside the ZE, connections provided by pre-terminated and tested interconnect cords need to be available for rapidly enabling MACs. Affordable shielded zone cabling solutions are recommended to address these situations.



Cost Savings


Even though more CAPEX (capital expenditure) will be necessary for a zone cabling installation, assessing total costs should also account for OPEX (operating expenditure). The performance of MACs is classified as OPEX, and studies by Siemon found there are hundreds of dollars in savings from each move, addition, or change when using a zone cabling design versus a traditional cabling design. Their study also discovered a tipping point when ROI begins accruing from utilizing a zone cabling design.


IT (information technology) needs for many organizations evolve constantly, which requires being able to quickly reconfigure floor space. An improved capability of supporting MACs will allow owners of facilities to achieve considerable ROI benefits from deploying zone cabling systems in a two to five year period. According to Siemon, the combined costs of CAPEX and OPEX for zone cabling designs will be invariably less than traditional cabling designs


Part 3 will continue discussing the basics and benefits of zone cabling.

8 Network Cabling Mistakes to Avoid – Part 1

9 Nov 2017

Cat5 Cat6 data cables Improperly installed twisted pair cabling can result in poor network performance, maintenance issues, and concealed expenses. The following article discusses eight network cabling errors to avoid. To get the best results for your cabling project, make sure to consult with a company that is experienced and provides excellent service.



Mistake No. 1: No Future Planning


If your company is moving to a new office space and new cabling will be required, it would be wise to avoid outdated technology and install equipment that will meet both your current and future needs. Labor costs will likely be the costliest aspect of the project. Although high-quality cable will not be cheap, it will be well worth the investment for your firm’s network requirements the next several years.



Mistake No. 2: Poor Cable Management


Implementing rack-based and ladder rack cable management will certainly raise the outlay for a project. However, sound cable management will ease maintenance and decrease downtime. You should be aware that cabling tasks do not end after installation. Additional cables will probably be needed, and configurations may be revised. Use a standard system for labeling and color coding cables for faster and easier identification. Doing so will speed tasks like repair, reconfiguration, and replacement.



Mistake No. 3: Parallel with Electrical Wiring


Generated by low voltage, the magnetic field conducted by data UTP (unshielded twisted pair) cables is an important feature for the conveyance of data. However, when UTP cables run parallel to electric wiring, there will be a disruption of its magnetic field. This results in garbled and noisy communication. Sometimes transmissions completely fail from point to point. Another negative effect is the extreme slowing of transmission.



Mistake No. 4: Nearby Devices and Fixtures


Noise can be introduced onto data cabling by more than just electrical wires. Fluorescent lighting, motors, and similar items that shed electrical or magnetic interference will wreak havoc on your cabling infrastructure as well. Make sure that in your planning, you leave a data cable pathway that avoids these kinds of hazards.


Part 2 will discuss four more network cabling errors to avoid.

Challenges and Planning of a Structured Cable System – Part 3

5 Jul 2017

 structured Cabling, Network Cabling, Washington DCAs previously discussed, the transition to IP-based security products and the rapid increase in business applications has resulted in end-users expecting greater video, audio, and data integration. These items require delivery over a standardized structured cable system. The following are the benefits offered by structured cabling for security systems. Part 3 will cover the Challenges and Planning of a Structured Cabling System.



Challenges


Typically, customers exploring the security market are advised that the only method for deploying a new access control system or an IP video surveillance system is through the removal of all current coaxial or UTP cable and then the installation of an entirely new Cat 5/6 structured cabling network.


Another method is much less disruptive and cheaper. It uses existing cable and employs an IP transmission system that is a hybrid. There are numerous hybrid transmission systems available that enable installers to make good use of extended Ethernet and PoE power distances through existing cable.



Planning


An effective, structured cabling system supports all the communication needs of a company with the integrated flexibility that enables users to link to CCTV cameras, VoIP telephones, access control points, and data devices. Planning a security system upgrade will include several crucial considerations as summarized below.




  • Applications: What will the system accommodate now as far as data, video, voice, and multimedia applications? What emerging technologies will be adapted in the future?

  • Service Lifetime: The service lifetime of a structured cabling system should be 15 to 20 years because it will be the spine of an organization’s communications network.

  • Compatibility: The applications that will function on the structured cabling system for the foreseeable future should be compatible with it.

  • Bandwidth: As bandwidth demand will usually increase because of business growth, a company must consider present and future demand.

  • Users: For the 15 to 20 year service lifetime of the structured cabling system, the estimated number of users during this period should determine the capacity required.

  • Modifications: Fiber-optic technologies are being developed rapidly, and the design of a structured cabling network should include flexibility in order to accommodate modifications and additional users.

The Organizations that Set Cabling Standards

27 May 2017

Data Cabling,Network Cabling,Atlanta GAThe TIA (Telecommunications Industry Association) and the ISO (International Organization for Standardization) are the primary organizations that oversee the development of structured cabling standards for the industry. Committees formed by the IEEE (Institute of Electrical and Electronics Engineers) provide assistance through testing and setting performance specifications for various standards.


Compliance with standards ensures the functioning of systems at specified levels, backward compatibility, and a greater selection of equipment will exist. General global recognition of standards permit utilizing equipment sourced from various countries inside computer systems. Requirements for the components of optical and copper cabling including cables, assemblies, connectors, cabling spacing and pathways, administration, field testing, and installation are standardized to make worldwide acceptance possible.


Technicians in North America typically use TIA standards, while the rest of the world uses ISO standards. Examples of organizations that set regional and national standards organizations are CENELEC (European Committee for Electrotechnical Standardization), CSA (Canadian Standards Association) and JSA (Japanese Standards Association). Their standards are generally compatible with TIA and ISO.


Different terminology used by TIA and ISO Associations sometimes cause confusion because they refer to the same item. For example, what the TIA terms as Cat5e is what ISO terms to be Class D. However, adherence to standards set by TIA and ISO ensure system cabling requirements are properly implemented in the categories below.




  • Insertion Loss – Decrease of signal strength down the transmission line.

  • Return Loss – Measurement of signal reflections on the cable.

  • NEXT – Near End Crosstalk Loss due to signal coupling.

  • Propagation Delay / Delay Skew – Elapsed time for signal to reach other end of cable or the delay between signal arrival at far end on slowest and fastest cable pairs.

  • ACR – Difference between insertion loss and NEXT.

  • ELFEXT – Identical to NEXT, but for cabling system’s far end.

  • PSANEXT / PSAACRF – Power sum alien crosstalk at near end / Power sum alien crosstalk at far end.


Due to ever-increasing data rates, the efforts of the standards organizations are assuming greater importance in terms of ensuring proper system design.

Things to Avoid in Running Network Cabling

28 Mar 2015

Date cabling,cable managementWhat can cabling that has not been installed properly do?


It can lead to a lot of negative outcomes such as paralyzed network performance, maintenance troubles and hidden costs. Network cabling can be  especially troublesome if it is installed by individuals without the proper knowledge and tools. When it comes to twisted pair cabling, there are many factors that you need to consider.


In the past, many companies installed different cable systems since twisted pair cabling was expensive. At present, full installation is still costly although a greater part of the expense is labor since raw cables is not pricey. Cable management is another concern. Use of ladder racks means additional cost but it reduces upkeep. Also be sure you label cables and to make use of color codes.


Unshielded twisted pairs are more practical in terms of usage. Magnetic fields are produced by low voltages that pass through your cables. This is a vital property of the communications cycle. And if you run unshielded cables along with electrical wires, the magnetic field can be interrupted. The communications becomes corrupted or noisy. You can expect that transmissions will not make it from one point to the other. Another possibility is that transmission rates will become slower. The cables should be perpendicular with electrical lines instead with the electric wires inside of shielded tubes at cross points.


Do not attempt to run cable alongside fixtures that create “noise”. Fluorescent lamps, motors and devices that generate electrical or magnetic interference will distort your cabling infrastructure. Install a data cable conduit that will create a buffer from these hazards. Also figure out the total distance of each cable. This is usually up to 100 meters. However, if cabling data rates reaches 10 to 40 GBPs, be attentive about distance restrictions related to the kind of cabling you plan to use. If you will run 10 GBPs for a maximum of 100 meters over twisted pair cabling, it is best to use Category 6 cabling.



Be aware of local codes.


This is important for safety concerns. In many areas, using PVC-covered cables is not allowed in air-handling spaces. When PVC burns, there is toxic emission that may prove dangerous to firefighters and other safety personnel who will try to navigate the location during emergencies. Failure to follow rules can lead to fines and forced replacement of cabling infrastructure. Contractors must be mindful of these regulatory standards.

Basics of Riser Cables

6 Mar 2015

Structured Cabling,Network Cabling Data Cabling Riser cables were designed for non-plenum vertical applications like between the floors of multi-story buildings. They are also described as backbone cables. These cables serve as the main conduit of a distribution system for data, video or voice. It originates from the point where communications go in through a particular edifice.  This cable comprises part of the structure backbone. Other components of this facility are the cable corridors, telecommunications cabinets, equipment rooms, correlated hardware, and support facilities. This cable variety must be fire resistant in accordance with electrical codes. Nonetheless, specifications are not as stringent compared to plenum cables.



Understand its Uses


Riser cables may be used for different forms of data communications which also includes CCTV video access. It is ideal as well for voice communications. One major concern is that requirements vary for each service. Hat is why planning can sometimes be quite complicated. Building managers are often pressed to predict their requirements given limited time and expertise. Quite often they will recommend creating split riser systems for multiple applications which follow parallel routes through the corridors, closets, and equipment areas.



How do you select the medium?


Perhaps, the primary concern is to stay within budget.  You can expect system designers to resort to trade-offs in delivering a broad assortment of services within the backbone system. Other factors that may influence their design are the following:




  • Provide an adaptable medium in relation to supported services

  • Identify the necessary useful life span of backbone cabling

  • Consider the technical needs of users


Standards are on hand to serve as a guide in the design of riser cable systems. There are appropriate benchmarks for optical and copper cable backbone structures. Some of the backbone cable categories include:




  • Copper-shielded and unshielded twisted-pair or UTP cables

  • Coaxial and twin axial cabling configurations

  • Single mode and micron multimode optical fibers


Physical locations supporting riser cables take into consideration the telecommunications service entrances and adjacent equipment rooms containing the main cross-connect. This can extend to the telecommunications closets that serve a particular location, intermediate cross-connects that serve a number of telecommunications closets, or horizontal cross-connects for a remote telecommunications closet or just one level of the building. The telecommunications cabinet is the point of interaction between backbone systems and parallel (same floor) wiring.


Riser cable systems in multiple-story buildings need to pass through equivalent closets making use of connecting conduits between the floors. Said design provides each floor access to the backbone and allows circuits to be distributed to all levels. The conduit and sleeves should go higher than the floor level by at least an inch and fitted with fire-stopping material. These should also adhere to electrical codes. The riser or backbone cable system essentially acts as the core of telecommunications infrastructure.
