    100-Gigabit Ethernet OTN Optical Interface Specifications

    The 100-Gigabit Ethernet OTN (Optical Transport Network) optical interface standards described below are supported on PTX Series routers.

    To determine which transceivers support each 100-Gigabit Ethernet OTN standard, see Supported Network Interface Standards by Transceiver for PTX Series Routers. The “Cables and Connectors” section in the description for each PIC lists which standards and transceivers are supported for that device.
