The switching mechanism is available in either a latching
or non-latching version with an integral position sensor for
both versions. Switches are available in On/Off, 1x2 and
2x2 configurations. There is also a high attenuation version
of the 2x2 switch used for node bypass applications.
The silicon based electromechanical multimode switch
uses a moving mirror actuation scheme to allow light to
pass through the switch on activation or to be blocked/
diverted when the switch is deactivated in a non-latching
configuration. This makes the switch particularly well suited
for fail-safe bypass applications.
A standard PCB footprint allows the switch to be conveniently
mounted. The standard switch is equipped with 1m
62.5/125 µm multimode fiber pigtails with no connectors,
but a variety of fiber and connector options are available.
