The HT6800-400GOEO is a 400G OEO (Optical-Electrical-Optical) Converter Transponder for the HT6800 DCI DWDM Optical Transmission System. The client side supports 1×400GE and 4×100GE service access via QSFP-DD slots, while the line side features a CFP2 slot for 1×400GE DWDM output. Supports 100GE, 100GE FlexE, OTU4, and 400GE service types with FEC enablement. Occupies 1 slot in the HT6800 chassis.
Supports single-channel 400G high-speed DWDM data transfer via CFP2 coherent module on the line side, enabling ultra-high capacity DCI links.
Client side supports 1×400GE and 4×100GE via QSFP-DD, accommodating 100GE, 100GE FlexE, OTU4, and 400GE service types with FEC enabled.
Supports 191.3–196.1 THz with adjustable wavelengths at 50/75/100/150 GHz intervals for seamless integration into any DWDM network.
Supports DDM digital diagnosis, OSNR monitoring, and real-time BER monitoring for proactive performance management and fault detection.
Supports ALS and LFP functions, plus transparent local fault and remote fault transmission, ensuring comprehensive optical link protection.
Full LLDP and RMON statistics, delay measurement, hardware/software loopback test, FEC enablement, and IDLE stream insertion for complete manageability.
