Optical Add/Drop Multiplexer
OADM
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.
