Fiber Characterization for 10G to 40G/100G Network Expansion

When it comes to high-speed transmission, especially 10G and 40G/100G, assessing fiber quality is a must. Once the basic parameters (i.e., loss, ORL, etc.) are under control, the next step is to qualify the fiber and ensure that it is fit to carry customer traffic. Polarization-mode dispersion (PMD) and chromatic dispersion (CD) optical testing become crucial at high speeds.

Maintaining Quality and Integrity

The primary goal of any communication network is to maintain the quality and integrity of the optical signal transmission. New or upgraded networks must be characterized to ensure their different parts and components do not induce bit-error-rate (BER) levels that exceed communication system requirements. This is why EXFO offers a full suite of fiber characterization solutions to fit the needs of today’s networks.
