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.
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.

This application note provides an overview of the basic concepts of PMD and the impact that strong-mode and weakmode coupling have on PMD testing; the accuracy of test instruments will also be discussed.
Thirty-one technicians took EXFO's speed test at BICSI 2014. They were asked to inspect and certify five UPC fiber connectors using the FIP-430B Fiber Inspection Probe and the MAX-FIP Intelligent Connector and Fiber Certifier. Watch the video to see timed results.
This training session will provide you with background information about the functionality and testing procedures of a DWDM system.
As bandwidth demands continue to increase, network service providers are looking at 40 Gigabit Ethernet and 100 Gigabit Ethernet networks to accommodate the ongoing traffic surge.
Packet optical transport (POT) networks are optical super-highways that use the most advanced technological enablers, from reconfigurable optical add/drop multiplexers (ROADMs) to amplifiers—and from very high bit rates to dense wavelength-division multiplexers (WDMs).
Packet traffic on submarine networks is steadily on the rise and submarine network operators must meet exacting services while optimizing performance.
EXFO offers various optical testing instruments and system configurations to perform on-demand troubleshooting of any fiber connecting to the equipment in order to help you reduce support- and maintenance-related expenses.
