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.
Dynamically selects any of 96 DWDM channels across 9 independent add/drop ports, enabling full ROADM functionality at each branching node.
Supports colorless and directionless ROADM operation, enabling any wavelength to be routed to any port without physical reconfiguration.
Per-channel integrated VOA with 0–15 dB dynamic range and 0.1 dB resolution, enabling precise per-channel power equalization across all ports.
Built-in Booster Amplifier (BA) and Pre-Amplifier (PA) ports eliminate the need for external EDFA modules, reducing chassis slot usage and cost.
Supports OSC 1510 nm for remote management, MON ports for optical power monitoring, and OTDR 1625 nm for fiber fault detection.
Port switching response ≤3000 ms, with ≤1400 ms for <2 dB steps and ≤2000 ms for <15 dB steps, enabling rapid network reconfiguration.
