Ciena Turin 900-0051-06 OC-192/STM-64 short-reach (SR1) interface module.
The Ciena 900-0051-06 is a Turin-family OC-192/STM-64 short-reach (SR1) interface module, hardware revision 05, serial-numbered SN98JMGGAA, built for Ciena’s Turin-based transport platforms (CN 3600/3616 chassis).
OC-192/STM-64 is a 10Gbit/s SONET/SDH line rate, and the SR1 short-reach optics on this module suit intra-office or short in-building spans where a full-distance line optic isn’t needed. The Turin platform provided high-density SONET/SDH transport and cross-connect functionality before Ciena’s later 6500-family platforms.
This is a spares/replacement item for sites still running Turin-based CN 3600/3616 transport. Tech-Star (UK-based, shipped worldwide) checks every interface module before it ships. Get in touch to confirm compatibility with your specific Turin chassis.
