Description
Overview
GAOTek transport platform DWDM passive optical add/drop multiplexer OADM card add or drop multiplexer OADM card 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.
Features
- Support 2 or 4 or 8 channel add and drop
- Plug and play: requires no configuration
- Green product: completely passive, needs no power and no cooling
- Low insertion loss
- 2C H maximum insertion loss ≤ 1.5 dB
- 4 CH maximum insertion loss ≤ 3 dB
- 8 CH maximum insertion loss ≤ 5 dB
- High channel isolation
- Adjacent isolation ≥ 25 dB
- Non-adjacent isolation ≥ 35 dB
