What is Opitcal Switch?

Optical Switch is a switch that enables signals in optical fibers or integrated optical circuits to be selectively switched from one circuit to another. It is mainly used in Optical Add /Drop, Optical Cross Connection System, and Optical fiber ring protection.

Optical switch may operate by mechanical means, such as physically shifting an optical fiber to drive one or more alternative fibers, or by electro-optic effects, magneto-optic effects, or other methods. Commercially available optical switches, either in MEMS or in mechanical, types have a standard switching speed of 2 ms or 5 ms.

LFO Optical Switches are base on Opto-Mechanical Technology with Proven reliability. Our Optical switch are designed for use in re-configurable optical add/drop multiplexers optical cross-connect systems and network switching for fault protection and restoration application, Collimated lens sand a moving mirror minimize insertion loss and improve the repeatability and stability of the switch parameters. The switch itself is directly mounted on printed circuit boards (PCBs), and is equipped with status contacts to provide an electrical readout of the switch position.
Latching operation ensures that the switch remains in position following power loss.

Our Optical Switch Series is GR-1221 qualified and designed for use in central office network applications. This reliable, miniature optical component is available as a 1x1, 1x2, 1x2 dual core, 1xN, 2x2, 2x2 dual core optical Switch.

Besides Optical Switch, we also Fused WDM module, Filter WDM Module and PLC splitters for FTTX applications.
