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

Overview

    The 1x2 Singlemode RS232 Optical Switch Module from Coreray (Guangxi Coreray Optical Communication Technology Co., Ltd.) is a high-performance optical routing device designed to meet the growing demand for automated and intelligent light path control in modern fiber optic networks. With the rapid expansion of 5G infrastructure, data centers, and fiber sensing systems, the ability to switch optical signals remotely and reliably has become critical. This compact module allows one input fiber to be selectively connected to either of two output fibers via simple RS232 commands, ensuring minimal signal loss and maximum isolation. Built with industrial-grade components, it delivers stable operation across a wide temperature range and is ideal for telecom, test & measurement, and sensing applications.

·         Low insertion loss: 0.8 dB typical

·         High isolation: ≥55 dB

·         Wide operating temperature: -20 to +70°C

·         RS232 serial control for easy integration

·         Singlemode fiber, 1260–1310 nm wavelength range

·         Compact, rugged design

 Technical Specifications

Why Choose RS232 Control?

    RS232 remains a preferred interface in industrial and telecom environments due to its proven reliability and simplicity. This optical switch module leverages RS232 to offer:

·         Broad Compatibility – Works with virtually any PC, PLC, or embedded controller that supports serial communication.

·         Robust Transmission – Differential signaling ensures noise immunity over distances up to 15 meters.

·         Easy Programming – Simple ASCII commands allow quick integration into existing control systems without complex drivers.

·         Cost Efficiency – RS232 hardware is inexpensive and widely available, reducing overall system cost.

Application Scenarios

1. Fiber Optic Network Protection & Restoration

    In metropolitan area networks, rapid fault recovery is essential to maintain service level agreements. By deploying the 1x2 optical switch at critical nodes, operators can automatically switch traffic from a failed primary fiber to a standby path within seconds. One telecom operator reported reducing network outage duration from 30 minutes (manual patching) to under 10 seconds after integrating Coreray’s RS232-controlled switches.

2. Automated Fiber Testing Systems

    During production testing of fiber optic components, multiple test ports need to be sequentially accessed. With the RS232 optical switch, test engineers can program automated test sequences that switch the optical signal to different devices under test (DUTs) without manual intervention. A leading test equipment manufacturer achieved a 40% increase in daily throughput and a 30% reduction in labor costs after incorporating this module into their test stations.

3. Multi-Point Monitoring in Fiber Sensing

    Fiber optic sensing systems used in perimeter security, oil & gas pipelines, and power grids often require periodic monitoring of numerous sensors. The 1x2 optical switch enables time-division multiplexing of a single interrogation unit across multiple sensing channels, greatly expanding the system’s coverage while keeping hardware costs low.

How to Select the Right Optical Switch

Choosing the correct fiber optic switch for your project involves several considerations:

·         Fiber Type – Singlemode for long-distance/high-bandwidth applications; multimode for short-reach/cost-sensitive links.

·         Wavelength – Ensure the switch’s operating range matches your system’s wavelength (e.g., 1310 nm, 1550 nm).

·         Control Interface – RS232 is ideal for industrial control; other options like RS485, USB, or Ethernet may be needed for specific setups.

·         Key Performance Metrics – Look for low insertion loss (<1 dB) and high isolation (>50 dB) to preserve signal integrity.

·         Environmental Tolerance – For outdoor or harsh environments, opt for wide-temperature models (-40 to +85°C).

Frequently Asked Questions

Q: Is this switch latching or non-latching?
A: It is non-latching (also called fail-safe), meaning it returns to its default state when power is removed. This is preferred in protection applications to ensure a known state during power loss.

Q: Can I control multiple switches from one RS232 port?
A: Yes, you can daisy-chain multiple units using addressable commands, or use an RS232-to-RS485 converter for multi-drop networks.

Q: What is the typical lifetime?
A: The mechanical design ensures >10 million switching cycles without performance degradation.

Q: Do you provide evaluation software?
A: Yes, we offer a free Windows-based GUI tool to test the switch and learn the command set. Contact us to request it.
