The patch panel comes with DWDM multiplexer and demultiplexer.
- 16 channels according to ITU-grid
- Independent of protocol and bit speed
- Insertion loss; 9.0 dB over 2 panels
- Can be mounted in 19" and ETSI cabinet/rack
- Passive, does not need any power supply
DWDM may be delivered in several types of panels and boxes from FOSS.
The most common are:
- FPM76-modular panel
- FP65-1U panel
- FPD76- wall box DIN
They are based on reliable passive technology and are delivered with SC or LC interface with PC or APC polished connectors. See separate data sheets for the different panels and boxes for more details about these.
Passive DWDM units are a reliable and reasonable method for transferring several wavelengths/signals over the same fibre (wavelength multiplexing). In this way you may increase the capacity of existing fibre-cable significantly. Combined with OADM you may add or drop wavelengths on the way between the end points. A big advantage of using passive wavelength multiplexing is also that the method is protocol– and bitrate independent.
A complete system with components for two-way communication (multiplexer and de-multiplexer) in both ends are made with two units .
