SONET/SDH OC48/STM16 Optical Interface Specifications
The following SONET/SDH OC48/STM16 standards are supported on M40e, M120, M320, MX Series, and T Series routers. The transceivers supported for each device might vary depending on the router. To determine which standards are supported for a transceiver on a particular device and router, see the “Cables and connectors” section for each device in the PIC guide for your router or the MX Series 3D Universal Edge Routers Line Card Guide..
