Optical Switches Specification:

DESCRIPTION
LIGHTech's optical switch modules are available in single mode and multi-mode models, and can be ordered with latching or non-latching features. 2x2 optical switches are available in blocking and non-blocking models. All of LIGHTech's optical switch modules feature excellent repeatability, very low back reflection, and low cross-talk.
