10G Optical Tranport Unit Cards（OTU）

10G OTU board is a service access module for optical fiber links. It can regenerate 3R (Retiming, Reshape, Reamplify) signals for 1.25Gbit/s~11.31Gbit/s services with arbitrary rate protocols, and can be converted into CWDM or DWDM standard wavelength optical signal.

It can be used in optical communication systems such as PDH/SDH/ SAN/Ethernet with CWDM or DWDM multiplexer/demultiplexer to multiplex multi-serviece into one fiber, it provides a high-quality solution for solving transmission lines with insufficient fiber resources and high fiber line loss.
