Computer cabling is the circulatory system of your network. If your cabling is done poorly or incorrectly, you will have problems with your network. This is an office system that rarely anyone sees, knows about or often understands, but its impact to daily operations is vital.

Neves Media installs all cabling neat and organized for the purpose of making diagnosing problems that may occur in the future much easier. We offer a large selection of cabling manufacturers so that we can be sure to provide you with the best solution to your problem with the best price.

What's the Difference?

Today, current cabling is done with Category 6 UTP data cable and, depending on your environment, could be plenum or riser rated cable. The difference between the two refers to the jacket surrounding the cable.
Plenum
Non-Plenum
Cat 6 Cable
Fiber Optic Cable

Plenum cable (CMP) is cable that is installed within the ‘plenum’ space of buildings. This is the area that can allow air flow for HVAC systems by providing pathways for returned air. In short, the ‘plenum’ space refers to the space above a drop ceiling and below the structural ceiling. The plenum designation refers to a rating for fire rated standards.

Non Plenum or Riser Rated (CMR) cable is cable that does not adhere or meet those fire rating standards. Non Plenum or Riser cable typically runs through non air circulating areas. This cable is often referred to as PVC (polyvinyl chloride), and is much less expensive.

Category 6 is the standard for Gigabit Ethernet, as well as the current standard for business installations. It is important to understand that for a network to be correctly installed to Cat6 standards, the wall Inserts, patch cables, patch panels, and cable must all adhere to Cat6 levels of performance.

Multi-Mode Fiber optic cable is used in most business office environments. Single Mode fiber is used over long distances and in scientific environments. Fiber is classified by core/cladding size such as 50/125 or 62.5/125 referring to micrometers. Like Ethernet Cable, fiber optics is broken into categories as well. Below we’ve outlined the typical fiber and distance limitations:
