Mems VOA with High Reliability for Optical Receiver Protection

Product Description

Dynamic Variable Optical Attenuator (DVOA) based on MEMS is an important component for power regulation in all-optical networks. It can realize the full remote control of all optical network. Here are some main applications: preset optical power balancing, channel transmission balancing, optical automatic gain regulation, optical receiver protection, etc. The DVOA product developed by our company adopts MEMS control chip and unique optical design, which makes the product more miniaturized, lower cost, and more rapid response, with higher stability and reliability, and easy to manufacture.

Features	Applications
High reliability	High transmission optical power
High stability	Optical path power balance
Low insertion loss	Channel transmission equalization
Rapid response	Optical automatic gain adjustment
small volume	Optical receiver protection
	optical on &off
