8ch OADM Optical Add Drop Multiplexing Card for Telecom/Datacenter/5G Network
The OADM board is an important part of the WDM system. It can realize the dynamic reconfiguration of the optical wavelength channel by the OADM module. That is to say, it can dynamically adjust the wavelength resource and fiber path in the optical path layer according to the change of traffic and demand in the transmission network Path resource allocation makes the most effective use of network resources
DWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations. With matching MUX/DEMUX units placed at each end of an optical link, multiple data channels can be combined and transmitted over a single-mode fiber trunk. The passive OADM modules can add or drop 2, 4, and 8 data channels at any point along the trunk.
