2CH CWDM Add Drop OADM Module Optical Add-Drop Multiplexer DWDM OADM Add Drop East and West Description An optical add-drop multiplexer (OADM) is a device used in wavelength-division multiplexing systems for multiplexing and routing different channels of light into or out of a single mode fiber (SMF). This is a type of optical node, which is generally used for the formation and the construction of optical telecommunications networks. "Add" and "drop" here refer to the

1270nm-1610nm Fiber Optic 18 Channels CWDM/DWDM Mux Demux ABS Box with 2.0/3.0mm SC/APC CWDM technology provides the flexibility to increase capacity of existing fiber infrastructure by enabling multiple channels/wavelengths over the same fiber cabling. Each channel carries data independently from each other, allowing network designers to transport different data rates. It's protocol and rate transparent supporting such applications as 1G/10G Ethernet, SDH/SONET and 8/4/2/1G
