Click 'Spec Sheet' for available configurations/part#


The FF Series fiber optic switch connects optical channels by direct fiber to fiber connection via a micro-mechanical auto-alignment platform and activated via an electrical relay. The advanced design significantly increase the performance, offering unprecedented low optical loss, little wavelength dependence with no coatings, high power handling, as well as low cost. Latching operation preserves the selected optical path after the driver signal has been removed.  The switch has integrated electrical position sensors. The switch is bidirectional and conveniently controllable by 5V TTL.

Using no lens, the FF Series switch can accommodate all type of fibers, including SM. MM, PM, double cladding, bendable, large core, small core. The FF switches provide performance for special fiber no other technology can match.
