Emerging Data Center Trends for 2018 – Part 1

4 Apr 2018

data cabling, installation , network2018 is shaping up to be a year with several exciting emerging data cabling trends. This article will discuss four that will be making an impact this year. Before embarking on a data cabling project, consult with an expert and experienced team to get the best results.



1) Avigilon


Increasingly used by many organizations concerned about security, video surveillance is being deployed in public places and schools to improve the security and safety of staff members, customers, and students. Avigilon technology dramatically reduces the time required for video review analysis that may aid in apprehending a suspect, locating lost children, and performing other security related tasks.


Video surveillance is now being augmented by advanced appearance search technology that will significantly improve its effectiveness. Rather than visually reviewing hours of video feed recorded by several cameras, the Avigilon search engine analyzes this footage to track a person, determine which exit they chose, and gather this evidence rapidly.



2) IP Video and Audio


Over the past few years, video and audio over IP has been quickly gaining traction because of advancing technology, decreased costs, and business acceptance.  AV system component makers have been featuring video and audio over IP in their products, bringing greater capabilities to AV systems.


Audio can be transmitted over VLANs for making emergency announcements or paging people. Current network infrastructure can be used to deliver audio and video to overflow areas from the audio and video systems of other rooms. Current network infrastructure can be utilized or placed on managed dedicated networks, aiding IT staff members who typically oversee AV systems.


System expansion is made easier because buying new equipment or creating infrastructure won’t be necessary. A client’s requirements can be kept in the forefront when building and scaling systems, avoiding the purchase of big matrixes or switches by acquiring encoders and decoders as needed by the system.


Part 2 will discuss Low Voltage Lighting Over POE and Passive Optical Networks.

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.

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.

Are you Ready for 1gb Internet?

13 Jun 2015

Your city might be poised for a dramatic increase in Internet speed into your office. Right now, you might have DSL Internet running on Cat5e cable at speeds of up to 25 - 30mb. But 1gb Internet is coming. New high-speed fiber optic networks are being built that will bring 1gb Internet to your office's network. It's coming.



So, are you ready for it?


The answer to that question lies primarily in the cabling that exists in your office. Most offices in the US have Cat5e cabling. Cat5e is not fully capable of handling 1gb speeds and will likely create speed issues at the desktop as users demand more bandwidth from advanced online and desktop applications. Cat5 cable is even slower. So, you will first need to figure out what kind of cable you have. The best way to do this is to look at the cable. Go to you wall closet or server room and look behind the patch panel. The patch panel looks like this.





And behind the panel is a bundle of cables. These cables have writing on them that describe the type of cable.That might look like this.





You should be able to see printed right on the cable the words "CATEGORY 5" or "CATEGORY 5E". If it says, "CATEGORY 6" or "CATEGORY 6A" than you are fine. Otherwise, you have cable that will not fully support 1gb Internet speeds into your office. Cat6/6A cabling is designed for 1gb and higher throughputs of data.


But getting ready for 1gb Internet is not just about the cable. You need the right cable and you also need the Cat6 compatible connectors, patch panels and a 1gb switch too. So, now you have a big decision to make.


















The Big Decision


What should you do? Recabling an office is a big deal. It's disruptive and it's expensive. But, wait. Is it really such a big expense and does it need to be disruptive? The cost of installing Cat6 cabling in an office is about $125 - $200 per drop. Each computer will need one drop. And you might have a few printers on your network too. So, the cost is about the same as a cheap computer monitor. And the boost in productivity will go on for many years to come.


Will it be disruptive? We can install new cabling in parallel to your existing network at night and on weekends. The switch-over is a weekend job too. Then we finish up by pulling out all of the old cable. That's called demolition. It might get a little dusty. But our team will do it's best to keep things as tidy as possible.


So, are you ready for 1gb Internet? If the service is available and you want a free on-site survey, contact us. We will be happy to come by and look at your office and prepare a Proposal for you at no charge and no obligation. If you aren't sure about the availability of 1gb Internet, contact us and we will find out for you.

Powerful Networks in Structured Cabling

16 May 2015

structured cabling, Data Cabling ,Cat5e, Cat6/6a CablingIt is known that structured cabling systems are fabricated to guarantee that information flows efficiently through the network. Such system are made up of transmission products installed based on appropriate guidelines in engineering design. These enable users to put into operation voice and data systems that capitalizes on speed.


This particular configuration has emerged as shared platform for multiple information technology applications. These include voice and data, building automation, security mechanisms, telecommunications conferencing, and fire alarms. This union transformed the structured cabling platform into the most essential network element. Therefore, it calls for a crucial investment in a very reliable, adaptable and scalable cabling structure.



High-performance Networks


This efficient and complex cabling scheme segregates the whole infrastructure into controllable blocks. After that, it puts them together to come up with a high-performance network. This end product is the vital link for many enterprises and all data hubs. Such a system facilitates consistency across the network particularly for commercial building structures. Consistency generates cost-effectiveness by standardizing maintenance processes, cutting down on manpower requirements, and improving reliability.


The “structured” design makes possible easy management by identifying specific distribution points, regular labeling and color codes, cabling management, and distribution techniques. As a rule, data facility managers use dynamic methodologies to fill the center with information technology equipment. This accommodates the evolving needs of business operations which frequently compel the need for the most modern IT equipment. Since companies rely on equipment as well as infrastructure, management believes requirements for additional IT capability should be made promptly. If the infrastructure is below par, upgrades will be much more difficult.



Crucial Concerns


The best IT specialists see to it that problems in structured cabling systems are dealt with immediately. One of the primary concerns is to employ highly competent service providers and coordinate entry points/space for each provider. This procedure enhances flaw tolerance of the overall system design. The high-performance model supports aggregate telecommunications requirements and thereby leads to a maximum returns on investments.


Centralized Intermediate Distribution Frames (IDFs) should be in centralized locations in the office facility. This will produce efficient cable management and will ease the addition of new equipment. This design technique has been adopted to avoid any disruption of the data unit or minimized once changes or upgrades are implemented. Telecommunications rooms contain the IDFs, main distribution frames and entrance facilities. Switches are installed in the middle of server rows for economical management.

Facts about Data Cable Testing

6 May 2015

structured cabling, Data Cabling,  cabling testerTesting always plays a vital role in the process of installing new cables or servicing existing ones. Regular testers for data cabling include length, wire crimper map, attenuation, return loss, and DC loop resistance.



Complex Cabling Needs


Cabling infrastructure requirements have become more complicated. More standards are being developed for cabling professionals in testing and troubleshooting copper and fiber cables. And there are special requirements as well as downsides in the implementation of new  technologies. From 10BASE-T to 100BASE-TX to 1000BASE-T and now to 10GBASE-T. It is now more crucial to keep in step with the most up-to-date techniques in cable testing too. In short, cable testing infuses a higher degree of assurance that installed cable links will attain the preferred transmission capacity for your data communications.



Cabling Tester Categories


Cable testing instruments have been manufactured with unique features for specific tasks. Costs, performance, and applications vary. These depend on the required functions. The three main functions are certification, qualification and verification. Although certain attributes overlap, each category answers a particular testing prerequisite.


Certification facilitates conformity to standards defines by the industry. These are instruments signal a “Pass” or “Fail” towards data testing compliance within standardized industry norms. These testing instruments will find out whether a cable link conforms to a category or class such as Cat6 or Cat5e. It is the last step required by most structured cabling installers towards approval of a new  installation.


Qualification determines if the existing cable is capable of supporting specific network speeds. This special class of testers is supposed to meet the up-and-coming requirements of network technicians who troubleshoot data networks. These testers perform checks to make a decision on whether a present cable link supports the requirements for fast or gigabit Ethernet. With these instruments, network technicians can identify and isolate cabling issues. While Continuity testers do not perform the series of tests set down by these standards and are not  considered certification tools.


Verification makes sure that cabling connections are correct. This type of tool performs a continuity test. It guarantees all wires in the cabling link have been attached properly to termination points at each end. For twisted pair cabling, there is an appropriate pairing of the wires. Such testing tools also confirm wire pairing and find out installation flaws such as split pairs. These can also help in troubleshooting by working with a toner to pinpoint a certain cabling link. These testing tools do not give out any information regarding bandwidth and data integrity.

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.
