OTU dual-directional and unidirectional protection card is a compact, high-density, optical converter with low-power consumption. It can support 3R(Re-amplifying, Re-timing, Re-shaping), wavelength conversion function, and be combined with MUX/DEMUX in order to realize the DWDM transport system. It is equipped with XFP 6-channel or SFP+ 6-channel optical module to support hot-swappable and any multi-service to access.

- Support CWDM / DWDM wavelength

- Support automatic laser off (ALS)

- Support multiple services and different rates

- Support hot swapping, low power consumption

- Transparent transmission- Ultra low latency
