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).
Presentation of EXFO’s WDM Investigator—the ultimate tool to cut down troubleshooting time and operational expenses in WDM networks.
An introduction to one of EXFO's latest innovations to its FTB-5240S/B-P, WDM-Aware. WDM-Aware offers the i-in-band mode—intelligent setups, optimized on a per-channel basis, which delivers accurate test results all automatically, all the time. WDM-Aware removes the uncertainty about test results, removes the guesswork, automates and speeds up tests, and thereby reduces OPEX.
Learn about how modern WDM network operators are faced with new challenges when measuring system performance, namely its OSNR. Gain insight into EXFO's new techniques and patented algorithms that currently being used for OSNR testing in WDM networks.
