The HT6800-400GTMUX is a high-performance 400G CFP2 Muxponder card for the HT6800 DCI DWDM Optical Transmission System. The client side supports 4×100GE service access via QSFP28 ports, while the line side accommodates one CFP2 400G DCO module supporting 1×200G or 1×400G DWDM output. Supports full C-band wavelength tuning and FEC enablement. Occupies 1 slot in the HT6800 chassis.
The 1U HT6800 chassis accommodates up to 4× HT6800-400GTMUX cards, delivering up to 1.6 Tbps total line-side capacity in a compact 1U form factor.
The 2U HT6800 chassis supports up to 8× HT6800-400GTMUX cards with mixed insertion of electrical and optical layer cards, delivering up to 3.2 Tbps total capacity.
Line-side CFP2 slot supports 1×200G or 1×400G coherent DCO module, enabling flexible capacity selection for DCI and metro DWDM networks.
Four QSFP28 client ports each supporting 100GE service access with FEC enablement, loopback function, and IDLE code stream insertion.
Supports 190.7–196.65 THz with adjustable wavelengths at 50/75/100/150 GHz intervals and tunable DCO output power for maximum deployment flexibility.
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.
