    SONET/SDH OC192/STM64 Optical Interface Specifications

    The SONET/SDH OC192/STM64 standards are supported on M120 routers, M320 routers, MX Series routers, and T Series routers.

    To determine which transceivers support the SONET/SDH OC192/STM64 standard, see Supported Network Interface Standards by Transceiver. The Cables and connectors section in the description for each MIC or PIC lists which standards and transceivers are supported for that device.

    The specifications are organized by distance supported.
