Product Description

OMD48 is suitable for core layer transmission in backbone networks and metropolitan area networks, meeting the requirements for multi-service bearer. It is used for high-speed optical interconnection between data centers, supporting single-wave 100G/200G/400G transmission, and meeting the requirements for short-distance and high-capacity data exchange.

OMD96 is suitable for high-capacity scenarios such as ultra-high-speed backbone networks, 5G fronthaul/midhaul, and cloud computing center interconnection.
