Important Facts About Cabling Infrastructure

23 Jan 2015

Network cabling that has not been installed properly may result in various communications issues. Even minor problems such as a connector that has not been terminated properly can prevent Power over Ethernet from performing well.

Wiring Standards

See to it that you use appropriate wiring patterns which are T568a and T568b. Refrain from bringing together T568a and T568b in the same cable. And always use premium quality Cat6 or Cat5e cables. We prefer solid over stranded wire.

Issues to Avoid with Cat6a Cables

22 Dec 2014

Stu Kushner

A 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.

Distinguishing between Cat5 and Cat6 Network Cables

12 Jun 2014

Network cables connect and transmit information between personal computers, storage area networks and routers. You can now find various models of cables. Your choice may depend on configuration and topology of the system’s architecture. The most common variety is known as twisted pair cable in local area networks. Numerous Ethernet networks use this type of cable. It is composed of four pairs of fine wires or conductors. Each pair is entwined several times to prevent obstruction from other cables and devices.

The CAT5 or Category5 is an example of twisted pair cable

Network Cabling, Data Cabling,cat5 cat6 cabling Sophisticated technology has made it possible for the new generation of entrepreneurs to enjoy Cat5, Cat6, and fiber optic cabling. These technologies amplify speed, enhance performance and reduce costs.

Cat5

Cat5 refers to structured cabling for transmission of data signals. This is used primarily for computer networks. Standard performance is a maximum of 100 MHz and fits into the Gigabit and Fast Ethernet. Cat5 carries other signals for video and telephony. Almost all Cat5 cables are unprotected and depend on balanced lines and twisted pair designs as well as differential signals to reject noise.

Cat6

Cat6 is considered standard for Gigabit Ethernet along with network protocols that require more speed than Cat5 cables. Cat6 is made up of four pairs of wires comparable to Cat5. Using all four pairs allows this model to support communications that are double the speed of Cat5. This translates to speeds of one gigabit/second.

Fiber Optic Cabling

Fiber optic cabling or optical fiber is distinct from Cat5 and Cat6. It utilizes light rather than electricity to transmit signals. It has a better signal compared to the traditional copper cables, so it sends signals more rapidly than is possible with copper cable. Optical fiber is also impervious to interference from electricity, which means that users can use it anywhere and anytime. Fiber optic cabling also allows for much longer transmission distances. Cat5 and Cat6 are limited to only 100m of cable from wallplate to computer.

Even telephone companies have started to phase out copper wires in favor of fiber optic cables. Technical experts of these firms are working to reduce the vulnerability of fiber optic cables to water. Using fiber optic provides enterprises the adaptability of augmenting bandwidth in just several days compared to the conventional copper circuits, which usually take a maximum of one month to upgrade. Fiber optic connections generally start at two megabytes, with dedicated upload and download speeds of up to one gigabyte.

Fiber Connection

The fiber connection will also facilitate the business-mode Service Level Agreement or SLA. This implies that business entities obtain a secured 99.99 percent uptime. If power failure and other issues occur, technical specialists can conduct repairs within a maximum period of four hours. Your business reaps the benefits of speed, assured uptime and fast service by a reputable company like Progressive Office Cabling. It makes use of high-quality cables along with connectivity parts as well as the most efficient systems in cable management. The company’s technicians have been trained properly to be able to respond to your demands. With a proven project management approach, effective communication is guaranteed during the entire project.

This kind of service is practically unmatched in this industry. Savvy users and business proprietors will know how to choose the service provider that can deliver solutions based on their requirements.

data cabling,,DC One of the most important things about cabling is to purchase cable not just for what you’re using now but for what you may run in the future. A rule of thumb is to install the highest-grade cable that your budget allows.

The standard is Ethernet. That means there are two basic types of cables to use: copper Ethernet and fiber optic Ethernet. Copper Ethernet cabling is generally used to connect the data center equipment to the end-user, while fiber optic cabling is used to network the infrastructure and to

What is “Structured Cabling”?

14 Mar 2013

Stu Kushner

Structured cabling is a telecommunications cabling infrastructure consisting of a number of standardized smaller elements called subsystems.

Structured cabling falls into five subsystems:

A Demarcation point is the connection point where the telephone company network ends and the customer’s on-premise wiring connection begins.

Equipment or Telecommunications Rooms contain equipment and wiring points that serve the users inside a building.

Vertical or Riser Cabling connects between the equipment/telecommunications rooms on different floors.

All About Cat6a Cable

11 Feb 2013

Stu Kushner

Cat6a Cabling in Atlanta It was once thought that copper cabling would never support speeds above 1 Gig, but Augmented Category 6, or Cat6a - has proven that wrong. Copper still lives and copper cabling may still be around at 40 Gig.

There has been much debate about which is the better option for supporting 10 Gig: Cat6a Unshielded Twisted Pair (UTP) or Cat6a Shielded Twisted Pair (STP)? Both solutions have their uses, and some key information can help installers make informed decisions.

Standards and Alien Crosstalk

The IEEE released the 802.3an 10GBASE-T standard in June of 2006, which specifies 10Gbs data transmission over four-pair copper cabling. The Telecommunications Industry Association (TIA) then began work on transmission performance specifications for the cabling. They published TIA Standard 568-B.2-10: Transmission Performance Specifications for 4-Pair 100 Ohm Augmented Category 6 Cabling in February 2008.

The new Cat6a standard extends the frequency of Cat6a cables to 500 MHz with specifications for a new performance parameter called Alien Crosstalk (ANEXT). Cat6a cables are fully backward compatible with all previous categories, including Cat6 and 5e. NEXT is crosstalk that occurs between adjacent cables and connecting hardware. The higher frequency signals of Cat6a makes ANEXT the limiting noise source for Cat6 and Cat5e systems.

Cat6a UTP vs. STP

Due to its ease of installation and familiarity among installers, Cat 6A UTP is today’s cabling of choice as it can support future bandwidth needs and 10Gb/s performance. In addition, the shield n the STP cable helps prevents electromagnetic and radiofrequency interference (EMI/RFI) on twisted pairs, helping eliminate the effects of noise from sources like machinery, generators, or medical imaging equipment, making STP systems the choice for industrial and healthcare facilities.

As most residential systems are not faced with EMI/RFI challenges, so UTP is still the recommended cabling type for home installations.

Cat6 Installation Tips

9 Jan 2013

Stu Kushner

Always study and document the required cabling layout and the distances between the equipment to be cabled before starting a Cat6 cable installation.

Refer to ANSI/TIA/ EIA 606 Document for color coding the different functions used in the system guidance. Use either PVC or plenum cable as required depending on where the cables are run. Fiber optic and/or copper cable may be required depending on the transmission speed and type of equipment.
