This application note outlines the OTN service disruption time (SDT) measurement approach housed in EXFO’s FTB-85100G (40G/100G) Packet Blazer. This module addresses the lab testing and qualifi cation of 40G/100G OTN transmission systems and fi eld commissioning procedures for system manufacturers and network operators respectively. Backbone and metro networks that support optical transport network technology (OTN as per ITUT G.709) carry many independent channels over different wavelengths on a single optical fi ber. With up to 100 Gbit/s per channel, OTN-based networks can transport legacy as well as packet-based services over the same network for better bandwidth effi ciency and network scalability. However, performance requirements are increasingly stringent making the testing and qualifi cation of these transport networks more challenging.
