Module, 8 channels CWDM, SM, 1271-1411

SKU: FPM76-8LCWDM-B-SLC
Stock:
excl. VAT

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

DESCRIPTION
CWDM 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. 


SYSTEM DESCRIPTION
Passive CWDM 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 using two units.
