Technical Analysis of the 1×8 Single-Mode Rackmount MEMS Optical Switch

I. Definition

Xionghua Photoelectric 1×8 Single-Mode Rackmount MEMS Optical Switch is an optical switch device based on micro-electro-mechanical system (MEMS) technology. It utilizes a single-mode fiber interface and provides optical path switching with one input port and eight output ports. It is designed for standard rack-mount installation. This device utilizes a microscopic movable mirror array to achieve precise control and switching of optical paths. It is a key passive component in optical communication networks.

II. Operating Principle

MEMS Micromirror Array: The core is composed of an array of micron-scale silicon-based reflective mirrors, precisely manufactured using semiconductor technology.
Electrostatic Actuation Mechanism: An applied control voltage generates an electrostatic force, which drives the micromirrors to deflect at a specific angle.
Optical Path Switching: The input optical signal is collimated and then irradiated onto the micromirror surface. The micromirror angle is precisely controlled to reflect the beam to the designated output port.
Closed-Loop Feedback System: An integrated position sensor monitors the mirror angle in real time to ensure switching accuracy and stability.
