1/2/4/8 Channels DWDM OADM, Dual Fibre, East and/or West, Optional Connectors and Housing

DWDM Optical Add Drop Multiplexer (OADM) is a passive optical device used in WDM networks for adding and dropping one/multiple 100GHz DWDM channels in the C-band into one or two fibres, while letting the rest of the wavelengths bypass to the needed destination. Using the DWDM technology can effectively add WDM capability to their existing and new networks, and extend the optical signals transmission distance.

DWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations, which are perfectly suited for 10/1G Ethernet, 16/8/4/2/1G FC, SDH/SONET, Video, CATV, FTTx applications. 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 fibre trunk. The passive DWDM OADM modules can add or drop up to 4 data channels at any point along the trunk.
