DWDM Passive Optical Add/Drop Multiplexer

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

              

DWDM Passive Optical Add/Drop Multiplexers	Support 2/4/8 channel add and drop
Achieve 2/4/8 channel add and drop	Plug and play: requires no configuration
	Green product: completely passive, needs no power and no cooling
	Low insertion loss:                       2CH maximum insertion loss ≤1.5dB                    4 CH maximum insertion loss ≤3dB                  8CH maximum insertion loss ≤4.5dB
	High channel isolation:                 Adjacent isolation ≥25dB                 Non-adjacent isolation ≥35dB

DWDM OADM modules are available in single-side (East or West) and dual-side (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, 8 data channels at any point along the trunk.
