SW Series
Fiberoptic Switch Modules
Description
The SW Series of fiberoptic switch modules connect a single
channel to one of several (up to five) channels. In addition
to the single pole configurations, the SW Series also supports
several two pole versions, as shown schematically. Note
that the 2x4 version can be driven independently as two 1x2
switches.
Both single-mode and multimode versions are available. In
operation, the SW switch connects the optical channel by
redirecting the optical signal into a selected output fiber.
This is achieved using optical prisms driven by a highly
precise mechanism and activated via an electrical control
signal.
The use of collimating lenses minimizes the insertion loss
and improves the repeatability and stability of the switch
parameters. The SW switches are optically passive and are,
therefore, transparent to signalling formats. Configurations
can be optimized for bidirectional performance as a factory
option.
