Synchronous Digital Hierarchy optical transport multiplexers include the FLX series of add/drop terminal multiplexers. These devices offer time-division multiplexing-based solutions covering STM-1 (155 Mbit/s or North American SONET OC-3) through STM-16 (2.5 Gbit/s or OC-48) hierarchies. Units feature both optical transport and digital cross-connect capabilities.
