Fiber Optic Photoswitches – Reliable Optical Path Control for Modern Networks
Optical photoswitches are essential components in fiber optic communication and sensing systems, enabling dynamic routing, protection, and monitoring of optical signals without the need for optical-to-electrical conversion. They provide fast, low-loss, and highly reliable switching for a wide range of applications—from telecom network protection to laboratory test automation.
At Shenzhen Feiyi Optoelectronic, we offer a comprehensive range of photoswitches designed for flexibility, durability, and consistent performance.
Key Technologies
| Technology | Features |
|---|---|
| Mechanical Optical Switches | Low insertion loss, high isolation, and excellent long‑term stability. Available in latching and non‑latching configurations. Ideal for network protection and signal routing. |
| Magnet-Optic Switches | Non‑mechanical design, fast switching speed (<200 µs), built‑in circulator/isolator functionality. Compact and highly reliable for aerospace and defense applications. |
| MEMS Optical Switches | Solid‑state switching with ultra‑high durability (>10 billion cycles). Fast response and low power consumption, suitable for multi‑channel monitoring and test systems. |
Common Applications
- Network Protection & Restoration
Automatic or remote‑controlled switching to backup paths ensures service continuity in the event of fiber cuts or equipment failure. Devices like the OLP1‑1 Optical Line Protection System monitor signal power and switch within milliseconds. - Signal Routing & Add/Drop
Configurable optical switches enable flexible routing for WDM systems, optical add‑drop multiplexers (OADM), and cross‑connects. Port configurations range from 1×1 to 1×N, 2×2, and beyond. - Test & Measurement
Programmable switches (with RS‑232, Ethernet, or UART control) allow automated testing of optical components, transceivers, and fiber links. Ideal for production testing and R&D labs. - Fiber Sensing & Monitoring
Multi‑channel switches expand the capacity of distributed sensing systems (DAS/DTS) and enable sequential interrogation of multiple sensing points from a single interrogator.
