The Network Master Family from Anritsu is made up of optical transport testers designed with scalable platform configurations for testing service interfaces such Ethernet, SONET/SDH, Fibre Channel, and DSn, and emerging MPLS-TP, PBB-TE, and ITU-T G.709 OTN. These devices feature two-port or four-port operation, which provides exceptional flexibility for testing network and transport equipment operating from 1.5 Gbps to >100 Gbps. This video presents an introduction on the Anritsu Network Master family of optical transport testers, and how they can ensure the optimization of network operations.
