Wavelength Division Multiplexers or Demultiplexers (WDM)
combine or separate optical signals with different wave-
lengths. They are passive optical components for uni- or bi-
directional operation.
TriplePlay WDM are multiplexer or demultiplexer which are used
to combine or seperate wavelengths which are standardized
for the common transmission of data, voice and analogue
CATV over one single fibre. The TriplePlay WDM are produced
with an improved filter technology.
Features
■ Low insertion loss and high channel isolation
■ High return l
oss
■ High thermal, mechanical and environmental stability to
meet the requirements of Telcordia GR-1209 and GR-1221
■ Compact design for easy system and customer modul inte-
gration
Applications
■ Singlefibre PON systems
■ Metropolitan networks
■ CATV systems
Designs
■ Supplied in various housing sizes with buffered tube pigtails
or reinforced cable pigtails
■ All connector standard types are available
