Structured Cabling Design and Installation
Review the following sections to learn more about cabling infrastructure elements,
and how Republic Telecom can help you meet your communications cabling objectives.
- Voice, Data, Cabling Services - Network cabling carries the lifeblood of your organization
- information. To minimize expensive data network problems, Republic Telecom follows
strict installation and testing guidelines.
- Coax Cabling Services - A critical piece of the infrastructure puzzle for our customers.
Coax has been the medium of choice for high fidelity audio, television, satellite
and broadband communications.
- Video Cabling Services - Video cabling can be closely associated with coaxial cable,
because most video applications require coax, but we also install twisted pair cable
for certain video applications.
- Twisted Pair Cabling Services - Unshielded Twisted Pair has been designed for use
in voice applications and local area networks. Because of the relatively low cost
this cable is widely used and is available in several different performance categories.
- Fiber Optic Cabling Services - We install, terminate and test multi-mode and single-mode
fiber. We've kept abreast of advances in the manufacture, termination and testing
standards of fiber optic cable.
- Server Room Installation Services - Because the server room is the centralized brain
of your structured cabling system, we take special care to design and install it
according to the highest standards.
Voice and Data Cabling Services
Cat 5, Cat 6 Cable
Today, your network cabling system carries the lifeblood of your organization -
information. The installation, material, quality of cable and testing procedures
are all much more critical in data wiring than in voice. The main reason for this
is that networks today are designed to carry large amounts of information at incredible
speeds. To accomplish this over unshielded twisted pair cable (UTP), many different
criteria must be met.
Who sets the criteria and standards for network cabling? The Institute of Electrical
and Electronics Engineers (IEEE - commonly called I-triple-E ) who work on developing
new protocols, the American National Standards Institute (ANSI), and the Telecommunications
Industry
Association / Electronic Industry Alliance (TIA/EIA) who issue the standards and
testing procedures.
We have seen network speeds increase from 10 million bits of information per second,
over Category 3 wire, back in 1991 to 1 billion bits (called Gigabit Ethernet) today.
With bandwidth increasing and reliance on the network at an all time high, getting
information to where it needs to be is becoming more challenging than ever. Ask
any IT Manager what their most common network problem is and you will most likely
hear them rant about cabling issues. In fact, cabling problems, which account for
over 50% of network problems, cost companies millions annually. The most common
problems are:
- Low attenuation
- Poor NEXT (near-end crosstalk)
- Poor ACR (attenuation-to-crosstalk ratio)
- Poor delay skew (data arrives at different times)
- Impedance
- Poor return loss (also known as "echo")
- Poor ELFEXT (equal-level far-end crosstalk) numbers for cable, connecting hardware
and channel
- Splices in cable
- Mis-labeled cables
All of these problems can be avoided if the cabling is installed and tested properly.
The cable must be installed following strict and specific guidelines and the testing
must be done using the right equipment calibrated for the latest standards (called
certification). Republic Telecom provides this with each cabling installation.
