The silicon micromachine based electromechanical multimode
switch uses a movable mirror process to allow light to pass
through the switch on activation or to be blocked/diverted
when the switch is deactivated. This makes the switch
particularly well suited for fail-safe bypass applications.
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 (i.e. FDDI) applications.
A standard PCB footprint allows the switch to be conveniently
mounted with control electronics.
The standard switch is equipped with 62.5/125 µm multimode
fiber pigtails with no connectors, but a variety of fiber and
connector options are available.
