The HT6800-400GQDD is a high-capacity 400G QSFP-DD Muxponder card for the HT6800 DCI DWDM Optical Transmission System. The client side supports 4×100GE service access via four QSFP28 ports (C1–C4), while the line side QSFP-DD slot accommodates 1×400GE, 1×300GE, 1×200GE, or 1×100GE services. Supports 100GE, 100GE FlexE, and other transmission types. Occupies 1 slot in the HT6800 chassis.
Line-side QSFP-DD slot supports flexible single-channel transmission at 100G, 200G, 300G, or 400G, adapting to diverse network capacity requirements.
Four independent QSFP28 client ports (C1–C4) each supporting 100GE, 100GE FlexE, and other service types with FEC enablement and IDLE stream insertion.
Supports 191.3–196.1 THz with adjustable output power and wavelength intervals of 75/100/150 GHz for flexible DWDM network integration.
Supports DDM digital diagnosis, OSNR monitoring, and real-time BER monitoring for proactive performance management and fault detection.
Supports ALS and LFP functions, local fault insertion, and transparent transmission of Local Fault and Remote Fault for comprehensive link protection.
Full LLDP and RMON statistics support (packet/byte count, port utilization, CRC errors), delay measurement, and hardware/software loopback test.
