Detailed information

6-Channel High-Speed Silicon-Based VOA

I. Definition

The 6-channel high-speed silicon-based variable optical attenuator (VOA) utilizes thick-film SOI (silicon-on-insulator) silicon photonics technology. It achieves an overall response speed in the microsecond (μs) range—with the internal silicon-based chip itself responding in as little as 300 ns—thereby meeting the requirements for high-speed response, miniaturization, and high reliability in optical transmission and optical sensing systems.

II. Features

High speed

Low polarization dependence

High stability

High repeatability

III. Application

Optical power control in communication networks

Multi-channel optical power balancing

Analog signal modulation
