Description

The DHODT-LM63 Optical multiplexer is a low cost and high performance optical line transmission multiplexer. The DHODT-LM63 combines up to 63xE1 interfaces over a single STM-1 link. Complete link redundancy is optional by adding a second STM-1 link module. Several transmitter options for different cable types and wave-lengths are available. This optical line equipment is developed for transmission in access networks, corporate networks, dedicated networks for railway and power companies.
