Mechanical Optical Switch: 1xN Fiber Optic Switches

Lfiber’s opto-mechanical optical switch (fiber switch) controls the direction of the light signal or changes states between transmitting and cutting off the light signal. The channel/port count is optional from 4 to 256, typically available for 4/8/16/24/32/64/128. It features modularized design, low Insertion loss, high reliability and stability.

An optical fiber switch represents the single most dynamic element in an optical network which traditionally can switch data between different ports of a network. For this reason, fiber switch is the key component to provide bandwidth management, ring interconnect, protection, or mesh restoration in the optical layer.

Mechanical Optical Switch (Fiber Switch)

An opto-mechanical optical switch redirects an optical signal by moving fiber or bulk optic elements by means of mechanical devices. It performs various operations allowing signals to switch from one state to another. This type of fiber switch is typically stepper motor driven. Lfiber’s opto-mechanical optical switch is cost-effective, its reliability, moderate insertion loss, and minimal crosstalk make them a widely deployed type of switch.

Functions and Principles of Opto-mechanical Optical Switch

Opto-mechanical optical switch functions by selectively switching a light signal delivered through an optical fiber or an integrated optical circuit to another. This type of optical fiber switch generally uses mechanical positioning systems, where movement of optical fibers or other components relative to each other permits switching of light from input fibers to output fibers of the system. In essence, the switch is the control for making, breaking, or changing the connections within an optical circuit. As with any other type of switch, this fiber switch has many uses. In summary, this fiber switch can be used in a variety of applications, large and small. The use of an optical fiber switch allows data to be routed where and when it is needed.
