The HT6800-WSS09 is a Twin 1×9 All-Optical Wavelength Selective Switch (WSS) card for the HT6800 DCI DWDM Optical Transmission System. Supporting 96 DWDM channels on the ITU-T 50 GHz C-band grid across 9 independently controlled add/drop ports, it enables fully reconfigurable ROADM nodes with colorless and directionless operation. Features integrated BA+PA amplifiers, MON, OSC, and OTDR interfaces. Occupies 2 slots.
The HT6800-TFFxxxx is a 4-channel Thin-Film Filter (TFF) MUX/DEMUX card for the HT6800 DCI DWDM Optical Transmission System. As a fixed OADM configuration, it achieves wavelength filtering using thin-film technology — transmitting specific wavelengths while reflecting others. Features 100 GHz channel spacing, built-in VOA on the EXP port, and cascading support via EXP ports. 10 wavelength band variants available. Occupies 1 slot.
The HT6800-OTDR is a high-performance Optical Time Domain Reflectometer monitoring card for the HT6800 DCI DWDM Optical Transmission System. Providing 24/7 automatic fiber monitoring across 8 ports with up to 130 km detection range and ≥36 dB dynamic range, it delivers real-time fault detection, location, and alarm reporting. Supports online monitoring and GIS-based test result display. Occupies 1 slot.
The HT6800-OP1 is a single-channel OLP (Optical Line Protection) card for the HT6800 DCI DWDM Optical Transmission System. Using dynamic synchronous optical switching technology, it provides 1+1 protection with sub-20ms switchover when fiber breaks or signal degradation occurs. Features SIG, A, and B ports. Occupies 1 slot in the HT6800 chassis.
