​The SN series are fast, non-latching MEMS switches. Available in configurations from 1x2, 2x2 and 1x4, they are the best choice where low Insertion Loss and low PDL are most important. The SN switches are also available for a wide variety of specialty single mode fibers such as 630 nm, 780 nm, 850 nm, 980 nm and also polarization maintaining fibers.
