General Information
Wavelength Division Multiplexers or Demultiplexers
(WDM) combine or separate optical signals with
different wavelengths. They are passive optical
components for uni- or bidirectional operation.
Bidirectional OTDR monitoring WWDM devices are
used inside the network for combining and separating
the traffic signals and the OTDR signals near the OTDR
measuring location, e.g. in the central office. They can
also be used inside the network for combining and
separating the traffic signals and the OTDR signals at
the premises near the optical network unit at the
customer side.
Features
■ Low insertion loss and high isolation
■ High return loss
■ High power resistance
■ Option of manufacture to customer specifications
■ High thermal, mechanical and environmental stability
to meet the requirements of Telcordia GR-1209 and
GR-1221
■ Multiplexing and Demultiplexing of wavelength
ranges lower than 1620 nm and higher than 1645 nm
■ Fully comply with standard IEC 61753-089-2
Applications
■ Uni- and bidirectional WDM transmission systems
■ Public and private fibre-optic networks
■ OTDR monitoring
■ Metropolitan networks
■ CATV systems
Designs
■ Supplied in various housing sizes with buffered tube
pigtails or reinforced cable pigtails
