SONET/SDH OC3/STM1 Optical Interface Specifications
The following SONET/SDH OC3/STM1 standards are supported on M Series, MX Series, and T Series routers. 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..
