1x2 and 4x4 switches, as well as on-off switches are realized
based on on-fiber technology. Switching speed is in the order
of the modulator speed, which is much higher than the
standard switches such as MEMS, solid state, mechanical etc.
Application of the on-fiber technology to switches makes it
possible to have excellent switching time without trading-off
the other device parameters such as insertion loss and
crosstalk.
