Summary: | For indoor local area network (LAN) the Polymer optical fiber (POF) is mostly
appropriate, because of its large core diameter and flexible material. A 1×2 optical switch for
indoor LAN using POF and a shape memory alloy (SMA) coil actuator with magnetic latches
was successfully fabricated and tested. To achieve switching by the movement of a POF, large
displacement is necessary because the core diameter is large (e.g., 0.486mm). A SMA coil
actuator is used for large displacement and a magnetic latching system is used for fixing the
position of the shifted POF. The insertion loss is 0.40 to 0.50dB and crosstalk is more than
50dB without index-matching oil. Switching speed is less than 1s at a driving current of 80mA.
A cycling test was performed 1.4 million times. Polymer clad fiber optical (PCF) switch also
fabricated and tasted. |
