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

In the rapidly evolving fields of biomedical optics and industrial testing, the integrity of the light path is paramount. Whether routing signals in a fiber optic switch for a laser therapy device or switching channels in an automated test setup, the reliability of the optical component dictates the accuracy of the result. At Guangxi Coreray, a premier fiber optic switch manufacturer, we often guide clients through the choice between different switching technologies.

While MEMS optical switch technology is popular for compact, high-speed applications in telecommunications, Mechanical optical switch solutions remain the gold standard for applications requiring exceptional optical performance, low insertion loss, and high isolation across a broad spectrum—particularly in the visible light range.

The Challenge: Switching in the Visible Spectrum (380-780nm)

A recent client in the bio-medical field required a robust solution for a spectroscopy system. They needed to alternate the light path between a reference sensor and a sample sensor without disturbing the light source. The key requirements were:

1.    Low Loss: Minimal signal degradation to ensure weak spectral signatures were not lost.

2.    High Reliability: A 24/7 operational environment with no downtime.

3.    Broadband Operation: Support for the entire visible spectrum (380nm to 780nm).

The Coreray Solution: OSW-1×2-M20

Our engineering team proposed the OSW-1×2-M20, a 1x2 Mechanical optical switch specifically designed for short wavelengths. Unlike general-purpose switches, this unit features collimators fine-tuned for 380-780nm and utilizes a precision motor drive.

Why Mechanical over MEMS in this case?
While a MEMS optical switch offers speed, the mechanical switch offered superior insertion loss performance (≤1.5dB) and Return Loss (≥35dB) at a cost point that was highly effective for the client's test equipment. The mechanical latching mechanism also ensures the path remains stable even if power is lost, a critical safety feature in some laser medical devices.

Implementation and Results

The client integrated the switch using our dual-control interface:

·         RS232 for automated computer control during long test sequences.

·         TTL for quick, manual overrides during calibration.

The results were immediate:

·         Data Integrity: The high isolation effectively prevented crosstalk between the two output channels, ensuring clean spectral data.

·         Ease of Integration: The SMA905 interface matched perfectly with their existing fiber probes.

·         Reliability: The switch has undergone thousands of cycles without deviation in optical performance, thanks to the rigorous temperature cycling tests (-40°C to +85°C) performed during manufacturing.

Conclusion: Choosing the Right Optical Switch China Supplier

This case highlights a crucial point in optical design: understanding the application environment is key. Whether you need the compact size of a MEMS optical switch or the high-stability of a Mechanical optical switch, working with an experienced fiber optic switch manufacturer is essential.

At Coreray, we provide both, but we pride ourselves on offering the engineering consultation to ensure you choose the right one. For applications requiring robust, low-loss switching in the visible spectrum, our 1x2 mechanical series remains an unbeatable solution.
