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 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 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.
