Fiber Characterization Services

Fiber characterization is conducting a series of tests on an installed link in order to assess its general quality and its specific ability to support particular applications. As data rates increase and systems become more complex there are many factors that can impair system performance. We offer 7 types of characteristic of the fiber

ETA Data Cabling Installers are expected to know the basic concepts of copper cabling installation and service—which are then applicable to all the procedures required to safely and competently install communications cabling. Basic electricity and safety; data communications basics; definitions, symbols and abbreviations; cable construction and types; cable performance characteristics; cabling standards; basic network topologies; basic network architectures; National Electrical Code (NEC®); cabling system components; DCIC installation tools; connectors and outlets; cabling system design; cabling installation; connector installation; cabling testing and certification; cabling troubleshooting; documentation..

For all fiber types and all wavelengths, insertion loss is monitored as a function of the bending angle. Although angles differ, the behavior remains the same. Fixed-angle bending generates excessive loss, and in some cases, leads to flawed identification.

ORL, which is caused by the reflective nature of network components including the fiber, mechanical connections and poor-quality splices, is a key parameter because it can affect transmitter performance and service quality. It can be measured using a backreflection tester, or an OLTS with a backreflection option.

A Fiber Optics Technician has a full understanding of inside plant optical fiber, connector, and splice performance characteristics as described in TIA-568 and can use these performance characteristics to create a worst case power budget for a fiber optic cable plant. An FOT can proficiently troubleshoot, perform optical loss testing as described in TIA/EIA-526-14A and perform connector endface evaluation as described in TIA-455. Using an OTDR an FOT 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-568.

Chromatic dispersion (CD) and polarization mode dispersion (PMD) are speed-limiting phenomena that hamper transmission in high-speed networks, starting at 10 Gbit/s. They threaten the integrity of a signal and affect the quality of service.

olarization mode dispersion (PMD) means that the group velocity dispersion of the two orthogonal polarizations in the fiber are different and cannot be simultaneously compensated by a single DCF.
