1×16 Desktop Optical Switch with Independent Push Buttons: An Ideal Solution for Efficient Optical Routing and Automated Testing

As optical communication systems, fiber optic sensing networks, and photonic research platforms continue to expand in complexity, efficient optical path management has become increasingly important. The 1×16 Desktop Optical Switch with Independent Push Buttons and RS232 Serial Control provides a reliable and flexible solution for routing optical signals among multiple channels, enabling fast switching, automated testing, and simplified system integration.

Designed for both manual operation and remote control, this optical switch combines user-friendly front-panel push buttons with RS232 communication capabilities, making it suitable for laboratories, manufacturing environments, optical network monitoring, and automated test systems.

Product Overview

The 1×16 Desktop Optical Switch allows a single optical input signal to be switched to any one of sixteen output channels. The compact desktop enclosure features sixteen dedicated push buttons on the front panel, allowing users to select channels directly without additional software.

In addition to manual operation, the switch is equipped with an RS232 serial communication interface, enabling remote control through a PC, industrial controller, PLC, or automated testing platform. This dual-control architecture provides maximum flexibility for both standalone and integrated system applications.

Operating Principle

The system consists of:

• One common input port (COM)
• Sixteen output ports (CH1–CH16)
• High-precision mechanical switching mechanism
• Front-panel independent channel buttons
• RS232 serial control interface

When a channel is selected either through the front panel or via an RS232 command, the internal mechanical actuator aligns the optical path with the corresponding output port.

At any given moment, only one output channel is connected to the input signal, ensuring dedicated signal transmission without optical splitting or unwanted interference.
