Mini 2×2B Mechanical Optical Switch (Relay Type)
Product Overview
An optical switch is a core passive optical component used to selectively switch optical signals from one port to another in fiber optic lines or integrated optical circuits, enabling physical on/off control or path routing of optical signals.
Based on different technical approaches, optical switches are mainly classified into mechanical optical switches (including relay type and motor type), MEMS optical switches, magneto-optic switches, electro-optic switches, thermo-optic switches, and silicon-based ultra-high-speed optical switches.
Fholink's mechanical optical switches (relay type) offer a wide variety of models, including 1×1, 1×2, 2×2B, 2×2T, D1×2, D2×2, D2×2B compact mechanical optical switches, as well as Mini 1×2, Mini 1×3/1×4, and Mini 2×2B miniature mechanical optical switches.
