The FFLS Series Fiber optical switch features fast rise/fall <5ms for large core fiber up to 1mm in diameter. It directly couples a pair of fibers and is activated via an electrical relay. Our advanced design offers unmatched performance of ultra-broadband covering from 300 to 2400nm, limited only by fiber intrinsic transmission. It also features low optical loss, little wavelength dependence without coatings, high power handling, as well as low cost. The switch is bidirectional and conveniently controllable by 5V TTL. The latching operation preserves the selected optical path after the drive pulse has been removed, reducing power consumption. Additionally, the switch has integrated electrical position sensors for verification.
Using no lens, the Fiber-Fiber Series switch accommodates fibers of multimode, double cladding, and large core. Index-matching liquid can be filled to further reduce the loss <0.2dB.
