Optical coupler modules are passive optical devices which
allow the distribution and combination of optical signals. They
are used in public and private fibre-optic networks as nodes
for data transmission (telephone, cable TV etc.); further fields
of application are in measurement set-ups, measuring instru-
ments, and sensor technology.
The basic couplers are manufactured on the basis of an ad-
vanced Fused Biconcal Taper (FBT) technology to provide opti-
mum performance and longtime stability. The coupler modules
consist of a set of different or identical fusion couplers.
Features
Low insertion loss and extremely low excess loss
Different modul configurations: For standard configurations
see table “Optical parameter“. Other configurations, e.g.
1 x 7 or 1 x 11, are available on request.
High return loss, i.e. no reflections interfering with the
transmitter in analogue systems
High thermal, mechanical and enviromental stability to
meet the requirements of Telcordia GR-1209 and GR-1221.
Option of manufacture to customer specifications
Applications
Public and private fibre-optic networks
Measurement systems and test equipment
Optical transmission and monitoring systems
Module types
Coupler Modules come in distinct types, wavelength selective
or with broadband properties:
They are classified just like SM-Couplers (see basic information
Singlemode couplers):
Standard Singlemode Coupler Modules
Wavelength Flattened Coupler Modules
Wavelength Independent Coupler Modules
Extended Wavelength Independent Coupler Modules
Full RangeWavelength Independent Coupler Modules
