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.

Cable Basket Trays – Uses and Benefits

25 Jun 2015

Cable basket trays are described as go-to solutions for routing and supporting numerous cable runs. The wired frame Structured cabling, Data Cabling, DC enhances air circulation and cable ventilation. This can be appropriate beneath desks, elevated floors, or hanging tray systems. You can assemble basket trays for intersections, horizontal sections, mounting braces, hardware, and tray cutters.


The cable basket tray made of welded steel wires is considered the most popular support for copper and data cabling. The basket is light-weight and easy to install with complete array of cable tray accessories. Solid basket trays are recommended for heavier wires. These baskets are fabricated to withstand natural elements. Although the material is not solid steel, it is capable of protecting cables from corrosion and last longer.




Cable Distribution and Management


The cable basket makes possible efficient dispersal and management of cables. This process is accomplished by arranging cables inside the basket trays instead of pulling them through pipe lines. The act of yanking is certainly harder and time-consuming rather than using baskets. Laying down wires in the basket take only minimal time and ensures that cables are distributed evenly around the structure.



The baskets can be stretched along the building just like pipes. However, baskets are open facilitating easier access to the cables. At the same time, it provides sufficient protection to the network cabling system. Cable baskets are lighter with easier functions compared to trays which are quite bulky. Technicians can finish more installations in one day because of fast installation.




Installation Guidelines


Incidentally, it is important to make sure that cable trays should be installed as an inclusive system. The tray should be complete with all the supports mechanisms, fasteners, guards, connections, flexible vertical and horizontal spice plates. You have to mount cable trays so the joints will be accessible for inspection and modification. Support systems are needed so the distance does not go beyond the required measurements. Install intermediary support devices in case the weight of the cable is more than tray rungs’ load capacity.


Erect supports from channel members, twisted rods and other accessories provided by the cable tray manufacturer. Organize the supports in bar or wall-bracket models as called for by the application. Make sure to take away sharp border s from cable trays. You can attach the tray to the spice pates but use square neck-carriage bolts and self-locking nuts. The cable tray should support the building structure. Finally, mount the cable trays with sufficient space to allow access for the installation of network cables.

Cable Network Trays as Support Systems

12 Jun 2015

cable network trays, Data CablingCable trays for networks are support systems that can be mounted on walls or hang up from ceilings. The trays are fabricated from aluminum or steel. These come in deepness of 2, 3, 4 and 6 inches. There are also multiple designs like trough (single rail), ladder, basket, and wire-mesh. The single rail is designed either with single or several options.



Types of Trays


The solid bottom trays support delicate cables. On the other hand, the center spine model is made up of a central support mechanism supporting the cable with the tray dangling from rods. This tray is important to the data communications market. The single-rail variety mounted on the wall is similar to center-spine. However, the treads can be found only on one side. Wire way is a system that is fully enclosed and provides no access to cabling inside.


Locations where cabling trays are required as well as cable types these carry have evolved during the last two decades. Cable trays are installed not only in power plants and paper mills but also in government facilities, schools and call centers. Certain manufacturers supply product categories produced for installation with uncommon requirements. For instance, the cable tray should be very robust so it can link a span of 30 feet between support systems. The short span variety supports four to five feet or limited space requirements of newly-installed components. Problems are resolved by using different types of cable trays.



Product Selection


The key to this is careful product selection since a single tray will not fit into all requirements. This offers the perfect solution. The main consideration is there are various instruments in the tool box of cable trays. You only need to match up each application for the ideal solution. Right now, there is an increasing need for big-sized trays so it will be possible to add more able in the future.


Modern installations entail manufactured support systems that can effectively hold both Category 5 and 6 cables. While cable performance becomes more efficient, cable and connector makers are also offering warranties for their performance. Along this line, the appropriate cable tray is needed so that cable performance will not be adversely affected by improper cable management.



What are the Benefits?


Contemporary cable trays have multiple benefits. These include the capacity to carry heavy weights. Installation is also faster and less complicated with reduced fitting time. Fixtures like risers, reducers and bends may be built on site. The applications have also expanded to several sectors such as industrial, infrastructure, commercial, food, and data hubs.

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.

Designs of Optic Fiber Cables

12 Feb 2015

network cabling,Data CablingmOptical Fibre CableOptical fiber cabling is made up of a fiber core and a protective layer. The shield is typically coated with a polymer. It protects the cable from damage and does not contribute to optical wave guide properties. The coated fiber is a durable synthetic resin serving as a support for the cable’s core. Protective jacket layers are added depending on the cabling application.



Fiber over Copper


Fiber has benefits over copper. Fiber optic transmission does not emit Radio Frequency Interference or RFI. This guarantees secured communications since light waves can't be easily intercepted. On the contrary, copper wires give off signals that interfere with other electronic equipment. That is why utility firms now run power lines with fibers

Cabling Pointers for Effective Data Center Management

5 Feb 2015

Structured Cabling,Office Cabling,datac enterThe data center supports the lifeblood of corporate enterprises. Communications stop due to the malfunction of this facility. Unfortunately, multiple issues can affect the data hub and incorrect cabling can be one of them. Planning is the key to boosting the efficiency of data center cabling.



 Here are some things to consider:



  1. Measure cables with care. Otherwise, you produce a twisted “rat's nest” and an unnecessary waste of money.

  2. Put a label on both tips of your cables which include patch and short runs. This will be useful if you need to test a cluster of circuits. It will not be confusing if you unplug several patch cables. You know where each single cable is connected. The marking system must be consistent at all times.

  3. Never rush on termination of cables. And redo in cases where cables lose connectivity. Avoid purchasing and using cheap products. You will end up spending more in the long-term.

  4. Test the cables first and make sure it passes the mark for continuity.  If not, you have to do it all over again. And always use a high-quality tester to avoid unwarranted work.

  5. Patch cables must be kept short. Remember that rack servers are only one foot away from each other. Patch cables with a length of three feet are definitely not appropriate. Combine testing and terminating capabilities to make sure that patch cables connect accurately. Additional lengths will cause a lot of twisting.

  6. Come up with a color coding technique. A single color is ideal for patch cables and cable runs. However, it is possible to utilize specific color cables for specific purposes. Avoid random colors. It will be easier to follow cable functions and resolve problems if your color has a purpose. Blue for data, white for voice is a common standard.

  7. Your design must be cable-friendly. Do not put a rack in a place where it is not possible to run your cable effectively. You may end up with cables dropping from the ceiling or scattered on the floor. Expansion should also be in your planning so you know when and how to make adjustments.

  8. Separate electric wires from Cat5/6 cables. Power lines can distort communications. The effects will be to have connection and data transmission issues that can result in data corruptions.

  9. Be careful about excessive temperature. Make sure that the cables are cool and not hot since this can result in cabling decomposition. The data center should be designed in a way that servers and networks are always at a comfortable temperature.

Network Infrastructure Planning

28 Jan 2015

What is a network?Full_Network


The network is classified as a group of hardware and software components that connect devices within a company and link that entity to other companies in the world-wide web. The hardware for networking consists of network interface cards, computers, routers, switches, patch panels and cables. Software refers to network services and protocols that facilitate communications. The hardware components should be installed and configured before the software and operating systems are initiated. Network communications serve as the core foundation of the whole system. It makes up the services that build the network’s framework. The key is to determine the infrastructure based on the objectives that you have set so the architecture can scale up as a companies needs grow.



The Operating Systems


Begin by understanding the current setup. This will allow you to establish how to plan for your operational targets and objectives. Draw a full map of the current network. Include these all cabled connections, server information, location of devices in the network, and all of the users.  Complete this inventory first. Then, proceed with reviewing all available information in combination with the future goals. This will enable you to fully understand the required changes needed for deployment.


The operating systems or OS installed on computers make up the primary software components in a cabling infrastructure. The OS contains protocols that facilitate network communications. It also consists of applications and services that secure the data. Conventional features include connectivity, security, control of access, and routing/switching functions. There should an existing network before installing servers to support applications. These consist of file, print, web, messaging, application, and database servers.



Meticulous Planning



  • Document the physical hardware and software components

  • Decide on the actual location of each components.

  • Determine configuration requirements.

  • Buy, assemble and mount the hardware.

  • Install and configure your OS, apps as well as other software.


Be sure to understand the network’s physical design. If there are multiple heavy or data intensive workloads, servers will need more bandwidth and connections to deal with the data traffic. Network resources need to  allocated among the numerous applications which mean that vital applications can affect performance considerably. Planning becomes an integral component of development and should be specific to the business plans.


Keep track of existing workloads and use performance results as a reference. There should be proper tests to determine the performance of your network. Speculation is not advisable because that can cause mistakes and overspending.


As always, Progressive Office is available to assist with project planning. Please call or email us anytime.
