400G OEO Transponder
The 400G OEO / Converter / Transponder is a high-capacity coherent DWDM transport module designed to convert and transport 100G and 400G client services over a coherent 400G DWDM line interface. The client side uses QSFP-DD interfaces and supports 400GE, 100GE, 100GE FlexE and OTU4 services. The line side uses a CFP2-DCO coherent DWDM module for up to 400G line-side transmission. The module provides advanced Ethernet performance monitoring, LLDP, latency measurement and FEC functionality. The configuration occupies 1 slot in the transport platform.
