Office Cabling for Performance and Efficiency – Part 1

22 May 2018

network cabling, office cablingIn some cities, office space is at a premium and very expensive due to rapidly growing demand. When a company needs to optimize its workplace, configuring their structured cabling is a good place to start. A project retrofitting the cabling of an existing office should have a minimum service life of 10 years. Cabling installed in newly constructed buildings should have a service life of 15 to 20 years.


Network architecture that emphasizes the design of local area network (LAN) cabling will decrease expenses as well as improve network performance and efficiency. The underlying basis for sound LAN design is TIA 568 and 569-B standards. Both provide guidance regarding hierarchy and placement of spaces for installation, covering work areas, building, campus & horizontal distributors, equipment rooms, and entrances. IT staff should become familiar with the trends that will be discussed below.



3 Crucial Drivers


Managers of networks should keep in mind the three most important drivers of connectivity: Wi-Fi, PoE (Power over Ethernet) devices, and IBW (In-Building Wireless) systems.


Now a very important need of every business, Wi-Fi extends LANs to meeting spaces such as conference rooms, giving their personnel mobility and flexibility. An IT network that did not adequately consider Wi-Fi during design may find it difficult to proceed with cable installation near enough to enable connection to WAPs where necessary.


Technology advances in the development of PoE will help maximize space by allowing cabling to power devices. The latest standard, IEEE 802.3bt, can provide up to 96W of power via a data cable, allowing new applications and expanding usage to high-performance wireless access points and surveillance cameras.


The rising demand for more mobility and the difficulty of maintaining cellular coverage over a large facility has led to the growing presence of dedicated IBW systems, deploying small cell technology and distributed antenna systems.


Part 2 will discuss Cabling System Performance and Densification of Networks.

Ethernet Crossover Cable Basics

24 Jan 2018

cable, installation, cabling, Washington D.C.The crossover cable connects two Ethernet network devices to each other. They were invented for temporarily supporting host-to-host networking when a network router or another intermediary device is not available. Although crossover cables appear the same as a standard straight-through (patch) Ethernet cable, their internal wiring structures are different.



Straight Through vs. Crossover


A straight-through cable is used for connecting two different kinds of devices, such as a network switch to a computer. In contrast, a crossover cable is for connecting two devices that are identical.


The straight-through cable’s ends can be wired in any manner, but both ends must be identical. This is different from the crossover cable’s internal wiring, which reverses the signals for receiving and transmitting. The first and third wires and the second and sixth wires are crossed.


High-quality Ethernet crossover cables have special markings which allow users to distinguish them from straight-through cables. They are often red in color and the word "crossover" will appear on its casing and packaging.



Crossover Cable Needs


Crossover cables came into use during the 1990s and 2000s because the most common types of Ethernet were unable to support direct cable connections between hosts. Intended for using specific wires for both receiving and transmitting signals, the original and Fast Ethernet standards required the communication of two endpoints through an intermediary device to avoid conflicts.


The Ethernet feature MDI-X has auto-detection for the prevention of signal conflicts, enabling the Ethernet interface to automatically determine and negotiate the expected signaling convention of the device at the other end of the cable. The majority of home broadband routers and Gigabit Ethernet adopted MDI-X.


As a result, crossover cables are only necessary for the connection of two Ethernet client devices if they are not configured for Gigabit Ethernet. Nowadays, Ethernet devices are compatible with crossover cables because they can automatically detect them.



Ethernet Crossover Cables Usage


Crossover cable usage should be limited to direct network connections. When a user tries connecting a computer to an antiquated router or network switch via a crossover cable rather than a standard cable, the link can be prevented from working.

Basics and Benefits of Zone Cabling – Part 3

20 Dec 2017

Structured Cabling,Network Cabling ,Data CablingAs discussed in Part 2, there are considerable cost savings from the deployment of zone cabling systems. Part 3 will continue discussing the basics and benefits of zone cabling.



Additional Zone Cabling Benefits



  1. Additional IP devices for audio & video, BAS, digital signage, voice, data security, digital signage, WAPs (wireless application protocols), etc. can be integrated easily into the current structured cabling system through ZE (zone enclosure) connections.

  2. Extra ports within the ZE facilitate fast MACs (moves, adds, and changes) of current service configurations.

  3. For easing installation and decreasing labor costs, tested trunking and factory pre-terminated cables can be utilized.

  4. Increased efficiency of pathway utilization will be realized for the entire facility space.

  5. Structured cabling system deployment will be speedier and cause less disruption.


Smart & Green Building Designs


Perfect for smart and green building designs, zone cabling systems can reduce labor expenses and waste of cabling materials. Centralized connections inside ZEs achieve greater efficiency for the routing of pathways. LEED credits provided by the United States Green Building Council (USGBC) can be maximized. In addition, cable sharing can support several low-speed and low pair count applications functioning on a single 4-pair cabling system. This achieves greater efficiency in cable and pathway utilization.



Summary


Modern workspaces are becoming more social and flexible, and they are increasingly reconfigured and updated with greater frequency.


Zone cabling systems allows flexibility in work spaces, facilitating faster and less disruptive moves, adds, and changes than traditional cabling systems.


Zone cabling allows for greater efficiency in the use of pathways and materials, which is required for smart and green building designs.


CAT 6A shielded cabling is recommended in zone cabling designs to achieve maximum performance.


Shielded CAT 6A zone cabling designs result in greater performance, better support of remote powering applications, and ZE termination flexibility at practically no additional cost in comparison to CAT 6A UTP designs.


Regardless of size, zone cabling installations planned with 25% spare port availability will considerably decrease client disruption and allow the facility owner to recover the expense for extra ports inside two to five years or after achieving the threshold for ROI.

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

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.

Structured Cabling, cables, Washington DC

The 5 Most Common Structured Cabling Errors – Part 1

19 Oct 2017

Structured Cabling, cablesStructured cabling systems are so standardized that good practices should merely entail following ISO/IEC, CENELEC or Telecommunications Industry Association (TIA) documentation for panel and outlet standards, cable pathway standards, maximum cable and patch cord lengths, patch testing standards, etc. Strictly doing so will invariably result in an installation that is professional and trouble free. In addition, as data speeds grow faster and faster, following industry standards becomes even more crucial.


Improperly installed cabling made up of shorter runs, which do not overly stress the system, may function well enough. In addition, data speeds may be quite beneath the cable specification capacity. As an example, CAT5e carrying 100Mbps and capable of 1Gbps will have ample margin of error. However, structured cabling systems still need qualified technicians for proper installation supporting maximum data speeds over the entire network as required.


The following will discuss the five most common errors of structured cabling. Remember to call an experienced and expert cabling installation team to get the best results for your company’s project.



Error No. 1


Considering cables as merely wiring is the first error. They are actually very important electronic components that provide the pathway for data from point to point within a network. These points may be a desktop PC, a network switch, server, router, and wireless access point. When you consider that cables make these connections possible, then you can understand how important it is to make sure that the cabling is of high quality and properly installed.



Error No. 2


Running data cables near power cables is the second error. Even when cables are screened, this practice is unsound. When data cables are running near and parallel to   power cables, noise emitted by power cables may infiltrate data cables. As the load carried by power cables fluctuate, resulting spikes or surges may radiate into the data cables, creating undesired noise decreasing the quality of the data transmission.


Part 2 will discuss three more common errors of structured cabling.

Data Center Cabling Best Practices – Part 2

13 May 2017

Cat5e Cat6/6a Cabling,Office CablingAs mentioned in Part 1, modern data centers must be flexible, scalable, reliable, and manageable, making best practices required. Part 2 will cover cabling for Modular Data, High Density/High Port Count Fiber Equipment, and Standards.



Modular Data


Increasing in popularity, modular cabling systems for fiber and copper connectivity introduces the plug-and-play concept, which simplifies cable installation and significantly decreases costs and labor. Typically, cables are factory-terminated and tested.


While modular cabling is less costly when the infrastructure is modified in-house, it will not be as flexible because of the possible required commitment to a vendor for ongoing compatibility.



High Density/High Port Count Fiber Equipment


When networking equipment gradually grows in density and port counts rise to several hundred, the proper management of the connected cabling will also require increased effort.


In the past, the direct connection of cables to individual ports of equipment with low port-counts was thought to be manageable. Unfortunately, the same task will be very time consuming for high-density/high-port-count equipment. Eventually, the addition or removal of cables directly connected to these ports will be almost impossible.


The utilization of Multifiber Push-On (MPO) cable assemblies featuring a single connector at one end of cable and multiple duplex breakout cables at the other end will ease cable management.


The concept revolves around pre-connecting high-density/high- port-count Lucent Connector (LC) equipment with LC-MPO fan-out cable to dedicated MPO modules inside a dedicated patch panel. Once completely cabled, this patch panel will work as "remote" ports. Ideally the patch panels should be located on top of the cabling equipment to facilitate access to overhead cabling. This method significantly decreases cluttering of equipment and cables, resulting in improved cable management.



Standards


The ISO (International Organization for Standardization) and TIA (Telecommunications Industry Association) are the main organizations that develop structured cabling standards for the industry. IEEE (Institute of Electrical and Electronics Engineers) committees do the testing and then set performance specifications.


Standards compliance makes sure that systems function at specified levels, allows backward compatibility, and a greater variety of equipment will be available internationally. Widespread global acceptance of standards allows the sourcing and use of equipment manufactured by different countries.


Color Identification and Naming Scheme will be discussed in Part 3.

Comparing Cat 7 to the Other Cats

3 Mar 2017

Data cabling, network cablingNowadays offices and homes utilize either a wireless (Wi-Fi) connection or wired network connection. Usually faster than Wi-Fi, wired connections also have lower latency. These two types of network connection continue to progress technologically, providing users ever increasing speeds.


In the case of home networks, the speed of the internet connection is typically the issue, and the cabling may not be a factor. However, a company must consider the specifications of particular cables and how these would meet its requirements in order to properly decide which to select. There can be a vast difference between the network speeds of the various Ethernet cables.



Types


Cables are differentiated by standard categories. Category has been abbreviated to “Cat” by the industry. Currently, the most common cables in use are Cat 5, Cat 5e, Cat 6, and Cat 6a. The newest type is Cat 7. Every type is backward compatible, allowing users to insert a newer cable into a device that was manufactured for an older cable without any compatibility issues arising.

Progress


With every new cable category, users were provided increased speed and decreased crosstalk. Newer category cables provided faster speeds at increased lengths of cable. The following offers comparisons at 100 meters of cable, illustrating the differences between the ethernet cable categories:

Cat 5 - Considered slow and inadequate for business networks, providing up to 100 Mb/second at 100 Mhz.

Cat 5e - provides up to 1 Gb/second internet speed at 100 Mhz.

Cat 6 -provides up to 1 Gb/second, and cable lengths up to 55 meters can give internet speeds of 10 Gb/second at 250

Cat 6a -can provides speeds up to 10 Gb/second, to 100 meters of cable length, at 500 Mhz.

Cat 7 - provides speeds up to 10 Gb/second to 100 meters of cable, at 600 Mhz.

History


Cat 5 was the standard in 1995, Cat 5e became standard in 2001, and Cat 6 was introduced in 2002. Arriving in 2008, Cat 6a is typically the newest cable the majority of companies have used because it is not considered necessary to update to Cat 7 yet. Cat 7a and Cat 8, which were respectively released in 2010 and 2013, are still waiting in the wings.

What is Certification and is it really necessary?

10 Aug 2015

Environmental Problems with Cat5e, Cat6, and Cat6A Cable


Cable must be installed so that external environmental factors do not have an effect on the performance of the network. Problems can occur at the patch panel punch down, at the wall plate jack and anywhere along the cable itself. Maybe an inadvertent kink is in the cable. Or there is a snag in the cable as it got pulled across a rough surface in the rafters above the drop ceiling. Or maybe the cable got too close to an electric line. Any one of these issues can degrade the performance of an individual cable.


There are two basic kinds of testing that is performed during the installation of cabling:




  1. Continuity Testing

  2. Certification


Continuity Testing



Continuity Testing is a test to insure that the wires in the connectors at the faceplate and at the patch panel are connected up correctly. There are 4 pairs of wires and each wire is color-coded. So, as the technician is connecting everything, a particular sequence is required. If a wire is connected in the wrong order, the cable will fail. This is a basic wire-mapping test. If this test fails, the connector and wires are re-examined and re-terminated. All of our cable installations include continuity testing.


But the only way to insure and guarantee full speed to every cable is to do Certification Testing on each cable.



Certification



Certification Testing is a performance test that utilizes a precision device that sends a signal from one end of the cable to the other. This test is the only way to test the data-carrying capacity of each cable. For example, Cat6A cable is rated to run at 10G/sec. But if you have an issue, the cable will work but it might be running at a slower speed. It passes the continuity test but it's not performing at 100%. Certification will find the fault, pin-pointed to its exact location so that our technician can fix it, retest it and fully certify it as 100% top-speed rated.


The Fluke DSX-5000 is a very expensive test device that we employ to test and certify our cabling jobs. It costs about an extra $10 per cable to get everything tested and certified. But without this test, we can't guarantee top speeds throughout your network. And, considering that most cabling projects have a useful lifespan of 15 - 20 years, this investment upfront is very cost-effective. It means you will have full speed to every device for the entire lifetime of your cabling infrastructure.


Certification includes a PDF report showing every cable and the test results.
