Bridging the network divide


Solutions and Services Portfolio

Network Survey and Auditing

Site and Network Certification - Certification tests are vital if there is a discrepancy between the installer and network owner after an installation has been performed.

Voice and Data Cabling - Network cabling carries the lifeblood of your organization - information. To minimize expensive data network problems and to add value to your business, River Valley Communications follows strict installation and testing guidelines adhering to EIA/TIA and BICSI.

Coax Cabling - A critical piece of the infrastructure puzzle for our legacy customers. Coax has been the medium of choice for high fidelity audio, television, satellite and broadband communications and is till used widely even though in most arena's they have been replaced by modern solutions.

Video Cabling
- 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 based on the complexity at site and requirements.

Twisted Pair Cabling
– 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 adhering to EIA/TIA standards.

Fiber Optic Cabling
- 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 cabling systems and use advanced splicing techniques for our installations.

Data Center Cabling
- 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. We are the leading industry solutions provider in the DATA Centre arena and have wide levels of experience and expertise to understand customers needs and to put them to work.

Network Cabling Systems - Site and Network Certification

Copper Cabling Certification

In copper twisted pair wire networks, copper cable certification is achieved through a thorough series of tests in accordance with Telecommunications Industry Association (TIA) or International Organization for Standardization (ISO) standards. These tests are done using a certification-testing tool, which provide “Pass” or “Fail” information. While certification can be performed by the owner of the network, certification is primarily done by data communications contractors. It is this certification that allows the contractors to warranty their work.

Need for certification
Data communcations installers who need to prove to the network owner that the installation has been done correctly and meets TIA or ISO standards need to certify. Network owners who want to guarantee that the infrastructure is capable of handling a certain application (e.g Voice over Internet) will use a tester to certify the network infrastructure. In some cases, these testers are used to pinpoint specific problems. Certification tests are vital if there is a discrepancy between the installer and network owner after an installation has been performed.

The Standards
The performance tests and their procedures have been defined in the ANSI/TIA/EIA-568-B.1 standard and the ISO/IEC 11801 standard. The TIA standard defines performance in categories (Cat 3, Cat 5e, Cat 6) and the ISO defines classes (Class C, D, E, and F). These standards define the procedure to certify that an installation meets performance criteria in a given category or class.

The significance of each category or class is the limit values of which the Pass/Fail and frequency ranges are measured; Cat 3 and Class C (no longer used) test and define communication with 16 MHz bandwidth, Cat 5e and Class D with 100 MHz bandwidth, Cat 6 and Class E up to 250 MHz, and Cat 7 and Class F with a frequency range through 600 MHz.

The standards also define that data from each test result must be collected and stored in either print or electronic format for future inspection.

River Valley has the necessary equipment to carry out the necessary tests so as to certify your network.

Fiber Certification

Fiber Optic Certification is similar to Copper certification with the difference of using OTDR test equipments to test the installed fiber.

An OTDR may be used for estimating the fiber's length and overall attenuation, including splice and mated-connector losses. It may also be used to locate faults, such as breaks, and to measure optical return loss.
In addition to required specialized optics and electronics, OTDRs have significant computing ability and a graphical display, so they may provide significant test automation.

Optical loss testing as described in TIA/EIA-526-14A and perform connector endface evaluation as described in TIA/EIA-455-57B. Using an OTDR, The techenician can effectively locate faults in a fiber optic cable, mated connector pair, or splice as well as evaluate optical fiber performance, mated connector pair performance, or splice performance for compliance with TIA/EIA-568B.
