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

8×1 Photonic Crystal Mechanical Optical Switch (OSW-8X1-LMA5)

Product Overview

The 8×1 Photonic Crystal Mechanical Optical Switch (Model: OSW-8X1-LMA5) is a high-performance 8-input to 1-output mechanical optical switch designed for optical communication test systems and laboratory applications. Manufactured by Coreray Optical Communication, this device utilizes advanced fiber-to-fiber coupling technology to support an ultra-wide wavelength range of 400–1700nm, making it perfectly compatible with photonic crystal fibers (LMA-5). It is an ideal choice for research institutions, optical equipment manufacturers, and metrology centers.

This mechanical optical switch employs a precision motor-driven structure combined with dual control modes (RS232 and TTL) to achieve fast and stable optical path switching. Insertion loss is kept below 15dB, while return loss exceeds 40dB, ensuring high-fidelity signal transmission.

The switch features 8 input ports and 1 output port. Inputs use FC/APC narrow-key connectors, and the output uses an FC/PC narrow-key connector. All pigtails are armored for enhanced durability and reliability. The compact housing measures 135×40×32mm, facilitating integration into various optical test platforms and automated equipment.

Technical Specifications

Detailed Specifications

1. Package and Dimensions

The switch features a compact metal housing (135×40×32mm) suitable for rack-mount, desktop, or embedded installation. The enclosure reserves space for fiber bending, allowing the fiber to be bent once before output. The conventional long-axis motor structure provides excellent vibration and shock resistance.

2. Optical Performance

·         Broadband Compatibility: Covers 400–1700nm, adapting to multiple scenarios such as biomedical fluorescence imaging, material Raman analysis, and fiber sensing.

·         Low-loss Transmission: Direct fiber-to-fiber switching avoids additional loss from collimators, achieving insertion loss <15dB and ensuring efficient signal transmission.

·         High Isolation: Crosstalk ≥50dB and return loss ≥40dB effectively isolate inter-channel interference, improving test and transmission accuracy.

3. Electrical Control

·         Dual-mode Operation: TTL level control suits automated test systems for fast batch channel switching; RS232 serial control is compatible with host computers for manual debugging and remote control.

·         Low-power Drive: 5V DC power supply with low power consumption allows direct integration into embedded devices or portable test terminals.

4. Pigtails and Connectors

·         Armored Protection: All input/output pigtails feature armored outer layers, resistant to pulling and bending, suitable for industrial workshops and outdoor base stations.

·         Clear Identification: Input pigtails are marked with yellow numbered sleeves for easy channel recognition.

·         Customer-provided Fiber Adaptation: Customers supply prepared double-ended fibers, and we perform precise alignment to ensure switching performance.

5. Environmental Adaptability

·         Wide Temperature Range: Operates from -20°C to 70°C, stable under extreme high/low temperatures.

·         Reliability Verification: Passed -40°C to +85°C / 48-hour temperature cycling test, ensuring long-term performance without degradation.

Usage Precautions

·         Fibers can be bent once inside the housing; avoid excessive bending (bend radius ≥30mm) to maintain optical performance.

·         Handle connectors with care when plugging/unplugging to avoid damaging ceramic ferrules.

·         Use only 5V DC power supply to prevent overvoltage damage to the control board.

·         The product has undergone full performance testing before shipment; do not disassemble the housing.

·         For customized orders, confirm pigtail length, connector type, and other parameters in advance; we will adjust the configuration accordingly.
