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

Product Overview

    The Coreray OSW-1X2-SM is a rugged, high-performance 1x2 mechanical optical switch designed for reliable operation in outdoor and remote environments where external power is unavailable. Housed in a durable 120x80x18mm ABS plastic enclosure with basic waterproof and dustproof protection, this switch is the perfect solution for emergency communication systems, outdoor fiber optic networks, and field maintenance.

    This fiber optic switch utilizes a latching mechanical structure optimized for 1550nm and 1625nm wavelengths, guaranteeing excellent optical performance with low insertion loss and high return loss. By integrating a 3V battery, the OSW-1X2-SM provides true "deploy and forget" capability, making it an indispensable tool for field technicians and system integrators.

Key Features

• Built-in Battery Power: Operates with an internal 3V battery, eliminating the need for external power sources and enabling rapid deployment in the field.

• Latching Mechanism: The mechanical self-locking design ensures a stable optical path and maintains its state after switching, preventing accidental toggling and saving power.

• Low Insertion Loss: Typical insertion loss of just 0.8dB ensures minimal signal attenuation and maintains high transmission quality.

• High Reliability: Engineered to withstand harsh conditions with an operating temperature range from -20°C to 70°C and verified through rigorous temperature cycling tests.

• Customizable Pigtails: Standard configuration includes 0.5-meter yellow tubing pigtails with FC/APC connectors, with custom options available upon request.

• Network Equipment Integration: Serves as a key component for optical attenuators, splitters, and other passive devices.

• Outdoor Cable Monitoring: Enables remote testing and monitoring of outdoor fiber optic cables without on-site personnel.

• Emergency Communication Systems: Provides rapid deployment capability for mobile base stations, disaster recovery networks, and temporary field operations.

Operating Principle of the OSW-1X2-SM Battery-Powered Fiber Optic Switch

The OSW-1X2-SM is a mechanical optical switch. Its core operating principle is based on a miniature relay-driven prism (or mirror) that physically directs the light beam from the input port to one of the two output ports.

1. Optical Path Switching: Light from the input fiber is collimated into a parallel beam. This beam is then directed onto a movable prism. When the internal 3V battery supplies power to the relay, it moves the prism precisely, steering the light towards either Port 1 or Port 2.

2. Latching Mechanism: This optical switch features a mechanical self-latching structure. Once the prism moves to the correct position, a mechanical latch holds it firmly in place. This ensures the optical path remains stable even after the drive voltage is removed, preventing unintended switching and consuming zero power to maintain the state.

3. Battery Power and Control: The integrated 3V battery powers the relay and a simple control circuit. A user can initiate a switch via an external button or trigger signal, making it completely self-contained and independent of external power grids.

4. State Memory: Because of the latching design, the switch has inherent state memory. Its current optical path is determined purely by the physical position of the mechanical components, ensuring high reliability and a long operational lifespan.

    In summary, this device is an "electrically controlled, mechanical optical path selector." It combines the precision of optical mechanics with the convenience of battery power to deliver a robust, low-power, and highly reliable solution for demanding network environments.
