How Improper Cabling Causes Network Issues – Part 2

12 Sep 2018

Structured Cabling Office Cabling Atlanta GAAs discussed in Part 1, the performance issues of your company’s network may be directly related to improper cabling. Part 2 will discuss Compatibility, Patch Cords, and Poor Installation.



Compatibility


Issues occasionally arise when coupling cabling and connectivity from various manufacturers. The use of jacks from one manufacturer with cabling from another, and then patch panels from a third firm is an example. This combination may result in compatibility problems. When components that are not intended by design to function together are used, network performance issues will likely result.


Purchasing top of the line high-performance cables, while utilizing lower-quality connectivity components, will produce a weak link in the chain. Cable of the highest quality will be unable to attain its full performance potential when it is married to jacks, patch panels, and plugs that are not rated to support its capabilities.



Patch Cords


Patch cords may be the top reason why there are issues in network performance.


Your company may have installed a high performance cabling infrastructure of the highest quality, but if low-quality patch cords were purchased to economize, network speed, signal quality, and overall performance will be compromised.



Poor Installation


Vetting the cabling services team you hire is perhaps the most important factor in the prevention of network performance issues. Check that the company you are considering has technicians that are properly trained and certified to install the cabling system you have chosen.


When cable installers are not properly trained, it will greatly increase the probability that your company’s structured cabling system will not be properly installed. Incompetent installation can result in problems such as improper pulling, excessive bending, and cable being installed too near sources of signal interference like large motors and machinery.


Poorly trained technicians will leave cabling that is not properly terminated or correctly polished. Sloppy work and insufficient attention to detail during installation will usually result in poor network performance, along with costly and time-consuming efforts to address the problems the substandard work caused.

"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

Network Cabling Issues

31 Mar 2013
Network Cabling, Data Cabling ,Washington DCA major part of creating a viable network involves the installation of a cabling system. A solid cabling system is a good investment that will not only meet your current networking needs, but will last through your next-generation network as well.

Modern Ethernet networks follow a “star topology”, where each device on the network connects its own cable to a hub. In a single room

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”.

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.

Wireless Access at Hotel Saves Clients

28 Dec 2009

I met with the General Manager of a Holiday Inn in Northern Virginia. She manages a 200-unit building in Arlington, Virginia, an affluent suburb of Washington, DC. Her property provides rooms and facilities to handle meetings and conferences for vacationers and business travelers. She told me that she is trying to get wireless access installed into her building because she is losing business and wasting money.


She said that her hotel is providing free Internet access but her competition is providing free wireless access. Clients and management prefer wireless because it is much easier to manage and access. Clients don't like having to plug in a cable and having to make changes to their network settings to enable network access. Management does not like having to deal with multiple failure points in managing the hundreds of routers spread throughout the building. There is one in each room.


So, they have a lot of complaints about Internet access. It is not convenient. Sometimes clients don't even have a patch cable. So, the problems are overwhelming for both sides. Additionally, they have Meeting and Conference Rooms that are not hard-wired. So, every time they schedule a Conference for a business client they also have to pay their Internet Service Provider (ISP) to extend a bundle of network cables into the Meeting and Conference Rooms. As you can imagine, this is a hassle and a large financial expense. It cuts into their profit margins. And it is also a major inconvenience for both the staff and the customers.


We have presented a proposal to install network cabling and I expect to get approval in the coming weeks. It will save them time, money and reduce their efforts in providing reliable and fast Internet to their clients. I will update this posting as things progress.
