Module, 1 x WDM, SM,LC/APC, 1310/1550-wide band

excl. VAT

Fiber optic module with a built-in WDM multiplexer and demultiplexer, terminated in LC connectors.

2-channel WDM, 1310/1550 nm, broadband

The module comes with a built-in WDM multiplexer and demultiplexer, terminated in LC connectors.

The module should be mounted in a 1U or 3U panel. There is room for 12 modules in the 3U panel and 3 modules in the 1U panel. Various modules can be placed in random order in the patch panels. This ensures a flexible and modular construction that can easily be extended with more modules.

  • 1310/1460-1620 nm
  • Can be combined with 4 and 8-channel CWDM
  • Independent of protocol and bit speed
  • Can be mounted in 19" and ETSI cabinet/rack
  • Passive, does not need any power supply

WDM 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  
May also be delivered in most splice closures.  

They are based on reliable passive technology and are delivered with SC or LC interface with PC or APC polished connectors. 

Passive WDM panels/modules are a reliable and reasonable method for transferring 2 wavelengths/signals over the same fibre (wavelength multiplexing). In this way you may increase the capacity of existing fibre-cable. 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 panels/modules .
