Issues to Avoid with Cat6a Cables

22 Dec 2014
Network Cabling ,Data Cabling,CAT2 6A UTPA newly popularized cable is Cat6a. It is the new “cable on the block” which has prolonged the life of copper cabling. Cat6a has the shielded twisted and untwisted pairs with different advantages and features. It supports Gigabit Ethernet up to a hundred meters. However, you need to understand and cope with several issues.

Contentions


The size of Cat6a cable is larger than Cat5e. Copper is inherently unreliable due to Bit Error Rates or BER. This is why manufacturers have designed Cat6a cables with a smaller cross-section. It takes up less space in the tray. Yet, this space is needed to minimize crosstalk between cabling pairs. The protective shield in Cat6a cable adds to the expense.

Electricity and Mechanical Facets


Aside from the electrical issues, Cat6a Untwisted Pair (UTP) is fabricated with bigger conductors. It has more rigid twists compared to Cat5e and Cat6 and these heavier conductors plus large and stiffer jacket combines to make for more difficult cable installation. Besides, the external diameter of the UTP means that the Cat6a cable takes up more room in the trays and conduits.

Electrical and mechanical issues should not be overlooked since this can affect performance. The physical stability of Cat6a is essential to its transmission performance. Cat6a can be more sensitive to degradation of signal compared to Cat5.

These may be produced by the following:



  • Cable twisting generates signal reflection.

  • Excess insertion pressure on cables can cause poor connector performance.

  • Weakness of RJ45 (communications) connectors.


For example, if the cable is wedged in a door or compressed or squeezed by a heavy object, can result in sporadic network problems which may not be easy to detect. Nevertheless, Cat6a functions at enhanced specifications compared to Cat6 UTP. Considering all of these issues it may seem that fiber cable will become the ultimate future for 10 Gigabit Ethernet. It is up to users and the market forces to make the choice.

Essential Facts About Cabling System

14 Dec 2014

Network cabling, NetworkTopologies.Your office cabling system is costly and complicated investment. It's also a commitment to an office design and structure that is not easy to modify. If you add more workstations later, new cabling might be needed.


Most offices have a structured cabling topology that hardwires the cables from wallplate to patch panel. With this system, modifications are less likely because the initial installaiont includes a planning process that should anticipate some expansion. By pre-wiring potential locations in an existing or newly-constructed building, future moves, additions or alterations are avoided. You can just transfer patched cables in the wiring closet. Also, it is critical to number the wallplates to match the corresponding patch panel number. This will make it much easier to relocate a workstation or to troubleshoot a connectivity problem.



There are several sub-systems to consider:



  • The Demark refers to the point where the Internet Service Provider's (ISP) data line comes to an end and hooks up with the cabling in the building.

  • The equipment room serves as storage for all apparatus and wiring integration points.

  • Backbone cabling are high-speed cables (typically Cat6 or fiber) that connect various floors or wall closets.

  • The horizontal cabling for links up the network space to individual wallplates. These are done through conduits and ceiling spaces on every level.

  • The telecommunications enclosures are wall or floor mounted cages that hold the network equipment; primarily the patch panels ands switches but also sometimes the server and Uninterruptible Power Supplies (UPS) too.


Installation and design of structured cabling is regulated by standards that identify the following:



  • Network data switches

  • Offices layout for voice & data communications for Cat5e or Cat6 cable

  • Fiber Optic cables for backbones

  • Modular connectors at the wallplate


These components will guide the layout of cables in order to fulfill the data access requirements of your office. All of the cables start at the patch panel on a mounted rack (about 19 inches wide) in the wall closet. From there, they traverse through the drop ceiling and down the walls to individual wallplates. Quite often a wallplate will host 2 or more connections. At the wallplate a short patch cable, usually 7 to 14 feet in length wil connect the computer, phone, printer or other networked device.


All cabling standards require that all of the eight conductors in Cat5, Cat5e and Cat6 cables are inter-connected in a precise color-coded pattern. The network cable connects each device but some devices can share a single cable. This is true for VoIP phones. Most VoIP phones have a jack for the network cable and then a jack on the phone for connecting the computer. This pass-thru enables the two devices to share one connection.

Handling Cat5/Cat5e Cabling

19 Nov 2014

cat 5e,Network cabling, cables, Atlanta GAInformation Technology specialists have to choose the kind of cable to utilize for their networks. Cat5 has been one of the main choices for decades. This is because Cat5 supports 10/100 Ethernet which includes Fast Ethernet. In recent years, Cat5e has become the dominant choice for new cabling projects. And Cat5e cable is also backwards compatible. Your computers, phone and other network devices will work on Cat5e cable.

Cable Testing And Certification

12 May 2014

cable testing, Network Cabling ,Data Cabling Cable testing and certification are obviously complicated terminologies that may be difficult for laypeople to understand. Nonetheless, it is important to become familiar with these functions since they have become common fixtures in your homes. It does not matter whether you are simply making repairs or installing new cables, testing always plays an essential role. Testing offers a degree of assurance that the links provide the necessary transmission capacity that supports data communications.


Cable testing implements have been designed with multiple features for a variety of tasks. However, these differ in terms of costs, performance and applications. Testing can be classified into certification and verification. Certification is vital because it ensures conformity of the cabling system to industry benchmarks. Certification instruments decide whether a particular connection complies with ISO or TIA (Telecommunications Industry Association) guidelines. In fact, it is the final step completed by structured cable manufacturers before granting warranties for new installations.


In this technology domain, certification is acknowledged as proof of professional status. The Fiber Optic Association (FOA) oversees adherence to certification requirements and authorizes schools to grant training that meets its standards. FOA programs are created and maintained by experts in the fiber optic enterprise.


Certification indicates that you have accomplished specific performance criteria established by the certifying organization. It includes knowledge, skills and abilities either through training or through experience acquired over the years.
Certification is not simply an ordinary license; it is official consent to do business within a particular jurisdiction. The majority of states in the country require licensing for service providers installing communications cabling. Be sure to check your local area and find out the requirements for licensing. Testing and Certification are the foremost steps in the cable installation process, and it is imperative that all components are tested carefully.


It is not enough to plug in the network equipment set-up and find out if it works properly. Certification is needed to prevent unnecessary and costly improvements or refurbishment in the future. Network examination and certification of all new installations as well as existing networks are provided for the whole infrastructure.


Incidentally, you also need to learn that in communications cabling, standards delineate the kinds of cabling, yardsticks that define cabling, connections, cabling architecture, and testing prerequisites. These standards can minimize downtime and installation costs. At the same time, standards capitalize on system availability and prolong the life span of cabling systems. Lastly, paradigms allow manufacturers to create systems that will accommodate current technologies and equipment without difficulty. The bottom line is to find the company that can do these things for you efficiently.
