​Bridging the connection between a faster core network and a more complex access infrastructure, metro and wide area networks (WANs) are undergoing a transformation. New technologies, WDM, 10GbE, OTN, are being deployed, while existing technologies, SONET/SDH and ATM, continue to provide connectivity between networks. JDSU's portfolio of test equipment, software, and systems enables manufacturers and operators to deploy metro networks with confidence and optimize the quality of all services delivered.
