Coreray: Leading Fiber Optic Switch Manufacturer - MEMS & Mechanical Optical Solutions

Product Overview

The 1×2 manual PM fiber optic switch from Coreray is a high-performance optical component designed for fiber optic communication systems, sensing networks, and laboratory environments. Engineered with polarization-maintaining (PM) technology and optimized for 1550nm wavelength, this fiber optic switch ensures stable signal transmission with minimal loss. Equipped with FC/APC connectors and a manual latching mechanism, it delivers reliable performance in both industrial and research settings.

Key Features

• High Polarization Maintenance:
       Uses PM1550 fiber to suppress polarization disturbances, ensuring signal      integrity over long distances or after multiple switches.

• Ultra-Low  Insertion Loss:
       ≤0.8dB (Typ) insertion loss, significantly lower than industry averages,      ideal for high-efficiency applications.

• Manual Latching Mechanism:
       Push-button design with auto-lock function prevents accidental channel      switching, enhancing operational safety.

• Wide  Operating Temperature:
       -20°C to 70°C, suitable for outdoor, industrial, and lab environments      without extra temperature control.

• High Compatibility:
       FC/APC connectors and 0.9mm red-colored pigtails for easy identification.      Durable ABS housing for long-term use.

Applications

• Fiber Optic Sensing Systems:
       Structural health monitoring, pipeline surveillance, and more.

• Optical Communication Labs:
       Ideal for component testing and link debugging with flexible manual      switching.

• Industrial Control:
       Signal routing in industrial Ethernet and smart manufacturing      environments.

• Test & Measurement Equipment:
       Used with optical power meters and spectrum analyzers for efficient      channel switching.

Working Principle

This mechanical optical switch uses a precision optical path and PM1550 fiber to maintain polarization stability. When the button is pressed, the internal mechanism switches the optical path to the desired output channel. Upon release, a latching system locks the position to prevent misalignment. Combined with FC/APC connectors, it ensures low reflection and high isolation (≥55dB return loss and crosstalk) at 1550nm.
