Canstar Fiber Optic Couplers
Organization of this Catalogue
This catalogue covers a wide range of components and options.
The first seven sections describe the fiber optic coupler prod-
ucts. The next section covers connectorized fiber optic cable
assemblies. The final section explains how to order fiber optic
couplers with factory installed connectors.
All specifications are subject to change without notice.
Specifying a Fiber Optic Coupler Part Number
All fiber optic couplers (with or without connectors) have a com-
mon part numbering structure, which is shown in the ordering
information section on each product. To identify the elements of
specifying a part number, please consider the following ques-
tions:
1) What type of optical fiber will the coupler be used with? If sin-
2) What are the number of inputs and outputs?
3) If singlemode - what is the operational wavelength(s) and
4) If it is a tap coupler, what tap ratio is required?
5) What degree of ruggedization of cable leads is required?
6) Are nonstandard lead lengths required?
7) Are connectors required on the leads? If so, which type?
Our customer service staff will be pleased to help you answer
these questions to define the correct component for your appli-
cation.
glemode fiber, which type? If multimode fiber, what is the
core/cladding/coating diameters? Is it graded or step index?
range?
Keep in mind, the more rugged the larger the enclosure.

The 1970s was the decade of development of the first com-
mercially practical optical fibers, cables, components and
systems.
Communications Research Center (CRC) in Ottawa,
Canada, was investigating principles for fiber optic branch-
ing devices.
A key breakthrough in 1977 resulted in the invention of the
Fused Biconically Tapered (FBT) coupler - a two fiber device
where each fiber had a tapered section that was fused to the
other fiber. Some of the light in the first fiber coupled into the
adjacent fiber.
Canstar was developing technology for pioneering fiber
optic system projects in Canada. In collaboration with CRC,
Canstar developed the FBT coupler technology into a com-
mercial product and introduced it to the market in 1978. The
benefits of FBT coupler technology rapidly displaced the
alternatives of the time, propelling Canstar to the forefront of
the fiber optic component marketplace.
Many technical advances have been made in FBT technol-
ogy over the last two decades resulting in the following prod-
ucts:
- introduction of multimode taps and splitters
- introduction of singlemode taps and splitters
- introduction of multimode star couplers
- introduction of singlemode WDMs
- introduction of wideband singlemode couplers
- introduction of singlemode star couplers
- introduction of taper fiber attenuators
- introduction of taper fiber filters
- introduction of narrowband WDMs and dense WDMs
Canstar has been at the forefront of most of these advances
and is proud to offer you a full range of fiber optic coupler
products.
Canstar couplers are used in every application of fiber optic
technology: telecommunications to data communications,
medical to military, commercial aircraft to railway, and from
down to Earth industrial to satellites in orbit.
