e JDSU Ruggedized Small Channel Count Switch Module (SR series) is used for
incorporating customized test assemblies and specialized applications operat-
ing multiple source measurement instruments, such as optical spectrum analyzers,
wavelength meters, and power meters.
e SR series switches are manufactured for harsher environments, and are specied
for a wide operating temperature range of –25 °C to +65 °C.
Both single-mode (SM) and multimode (MM) versions of the SR Series switch con-
nect optical channels by redirecting optical signals into a selected output ber. is is
achieved using a mirror driven by a highly precise mechanism that is activated via an
electrical control signal. Switching can be done by applying either a direct electrical
or TTL control. e SR series is available in both single-mode and multimode.
Using collimating lenses minimizes the insertion loss (IL) and improves the repeat-
ability and stability of the switch parameters. e SR Series is optically passive and
is, therefore, transparent to signalling formats and bandwidth. All congurations are
optimized for bidirectional performance.
