Wavelength Division Multiplexers or Demultiplexers (WDM)
combine or separate optical signals with different wavelengths.
They are passive optical components for uni- or bidirectional
operation.
High Isolation Filter WWDM are multiplexer or demultiplexer
which are used to combine or seperate signals with wave-
length from neighbouring optical windows. They are used as
band-pass filters and in high isolation WDM modules.
Features
■ Low insertion loss and high isolation
■ High return loss
■ High power resistance
■ High thermal, mechanical and environmental stability to
meet the requirements of Telcordia GR-1209 and GR-1221
■ Option of manufacture to customer specifications
■ Multiplexing and Demultiplexing of CWDM channels and/or
wavelength ranges around 1310 nm and 1550 nm.
Applications
■ Uni- and bidirectional WDM transmission systems
■ Public and private fibre-optic networks
■ Add-Drop-Multiplexing
■ Metropolitan networks
■ CATV systems
Designs
■ Supplied in various housing sizes with buffered tube pig-
tails or reinforced cable pigtails
■ All connector standard types are available
