How to Install a Patch Panel

27 Jun 2013

The process of installing a patch panel onto a wall begins with the preparing the wall to hold the rack. Most offices have drywall walls. Sometimes the walls are concrete if they lie along the structural boundaries of the building. This installation involved mounting the patch panel onto a wall that is drywall on top of concrete.


The photos below will illustrate what is involved in mounting a rack that holds the patch panel and switch.

RJ-45 Connectors Made Easy

18 Apr 2013
 Network Cabling, Data Cabling ,Cat5e, Cat6/6a CablingWhat is the difference between a Cat5 and a Cat6 RJ45 connector?

The easy answer is:  they are both cable connectors with a standard network plug and socket, often called an “Ethernet jack”.

Cat 5 and Cat 6 are UTP, or Unshielded Twisted Pair cables.  The difference defines the cables as Category (Cat) 5 or Cat 6 UTP cable. Both are terminated by RJ45 connectors.

Cabling Issues

11 Apr 2013

data cabling,,DCOne 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

Basic Structured Cabling

Cables,Network Cabling, Data Cabling, Cat5e ,Cat6/6a Cabling

"Structured cabling” is a complete system of cabling and associated hardware which creates a telecommunications infrastructure. This infrastructure can serve a range of tasks, such as providing telephone service or data transmission through a computer network.

Every cabling system is unique. Variations in the structure of the facilities housing the installation, the specific cabling and connections needs, use and function, as well as customer needs requires standardization to ensure acceptable system performance from increasingly complex systems. The American National Standards Institute (ANSI) is the responsible organization

What is “Alien Crosstalk”?

8 Mar 2013

 Network Cabling, Data CablingNo, it’s not ET calling home. “Alien Crosstalk” is defined as “unwanted signal coupling from one balanced twisted-pair component, channel, or permanent link to another”.


Alien crosstalk is not generally affected by common noise from motors, transformers, or florescent lighting fixtures. Alien crosstalk is specified as “a parameter for cabling to approximate the energy present when all cabling pairs are energized”.

All About Cat6a Cable

11 Feb 2013

Cat6a Cabling in AtlantaIt 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 Q&A

4 Feb 2013

Data Cabling ,Cat5e ,Cat6/6a CablingWhat is Cat6? Cat6 components are interoperable between different vendors and are fully backward compatible. Cat6 has the same nominal Impedance of 100 Ohms as Cat5 and 5e components, but with tighter tolerance on Impedance variations. Transmission parameters are specified to 250 MHz, compared to 100 MHz for Cat 5/5e.


Do Cat6 components behave differently?   The diameters of Cat6 cables range between 0.21 to 0.25 inch (5.3 - 5.8 mm) compared to Cat5/5e’s range of 0.19 to 0.22 inch (4.8 – 5.5 mm).   Cat6 also has a tighter twist length to reduce crosstalk interference.


What about installation?  Cat6 cables and components are installed similar to Cat5/5e. There are design and installation issues that contractors and installers must pay greater attention to; including cable terminations and the pathway fill.


Will Cat6 supersede Cat5/5e?  Yes. The only question is when. The installed cost for Cat6 cabling can be about 20 % higher than Cat5e, but prices will decrease as usage increases.


Will Cat6 deliver what is promised?  Yes. There are no technical obstacles. Test parameters and procedures to qualify Cat6 components to ensure interoperability between different vendor’s products are in place and detailed.


What about the installed performance compared with Cat5/5e?  The biggest benefit is much-improved Signal-to-Noise Ratio at the Receiver:  Cat6 provides about 16 times better Signal-to-Noise Ratio compared to Cat5/5e over a wide frequency range.


Why do we need Cat6? The real question is “is Cat5e good enough for today and in the foreseeable future?”  The answer is “Yes, but…”. Network switch ports are often at the “marginally compliant” limits of the IEEE standard and susceptible to cabling and temperature variations. Cat6 provides fewer bit errors than Category 5e for 100BASE-TX and 1000BASE-T applications.

Cat6 Cabling: What’s the Difference?

17 Jan 2013

Cabling is an evolutionary process. New challenges require new capabilities, and based on past trends and future projections, data rates will double about every 18 months. Running applications at 1 Gb/s pushes the limits of category 5e cabling, so doubling the bandwidth is like adding two or more lanes on a highway – you get faster and more efficient data “traffic flow”.


Streaming media applications such as video and multi-media are now commonplace, so the demand for faster data rates are increasing. These new applications will require the higher bandwidth of category 6 cabling.

Cat6 Installation Tips

9 Jan 2013
 Data Cabling, Cat5e Cat6/6a CablingAlways 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.
