Singlemode
Fiber Optic
Switch
FO5935
The FO5935 singlemode switch offers
unprecedented reliability due to its unique frictionless
MEMS*-based latching actuator and moving mirror
mechanism. Switches with well over ten million
cycles show no degradation in performance. The two
latched optical states, whereby one state allows the
light to pass through the switch while the other state
blocks or diverts the light into another fiber, can be
monitored with integral status sensors.
A simple 5V, 1 ms long pulse is all that is
needed to change and latch the optical state of the
switch. Re-application of a pulse to the same
electrical pins will change and latch the switch in the
alternate optical state. In addition to a fast optical
switching time of 2 ms, the switch offers a 10X
improvement in maximum cycle rate for demanding
applications.
The small switch size makes board layouts
easy without sacrificing the demanding packaging
requirements of Telcordia GR-1221. Bi-directional
and bit-rate independent operation is achieved due
to the optical transparency of the switch.
1x2, 2x2, and on/off configurations with operation
at 1300 and 1550 nm are available with standard 9/
125/900µm fiber pigtails. A variety of connectors are
also available.
