PM optical switch package diagram
Port Configuration
Adopts a standard 1×2 structure, with P1 as the common port and P2 as the switching channel port, supporting bidirectional optical path selection.
Electrical Interface
Equipped with dual-row
10-pin standard headers
(2.54mm pitch), compatible with conventional PCB driver circuits, supporting electronic switching and customized latching/non-latching modes.
Mounting Design
Features Ø5.5mm standard mounting holes, supporting direct mounting to the panel or chassis, suitable for automated assembly and mass deployment.
Mechanical Dimensions
The main body dimensions are approximately 27×12×8.2mm, with a total length of 37mm including the pigtail. The compact structure is suitable for 1U/2U rackmounts and high-density module integration.
Product Features
Adopts high-precision mechanical optical path alignment to strictly maintain the polarization direction of the input light during switching. With a typical extinction ratio ≥20dB, it perfectly fits polarization-sensitive systems such as coherent communication, fiber optic gyroscopes, quantum communication,
and precision sensing, preventing signal distortion and performance degradation.
Features epoxy-free and low-reflection optical path design, with typical insertion loss ≤0.5dB and channel isolation ≥55dB. It minimizes crosstalk to ensure high-quality signal transmission and reduce overall link attenuation.
The core optical path is epoxy-free, offering excellent resistance to temperature variation, vibration, and shock. With a wide operating temperature range and over 1 million switching cycles lifetime, it ensures stable long-term operation and
meets the strict reliability requirements of industrial
and telecom-grade equipment.
Compatible with both 1310nm and 1550nm PM bands, the most common wavelengths for telecom and metro networks. It adapts to long-haul transmission, metro access, and test & measurement scenarios, enhancing equipment versatility
and reducing inventory costs.
Supports single-mode/PM fiber customization, various drive voltages, and both latching/non-latching,
fast-switching/low-power versions.
Pigtails can be customized with FC/LC/SC/APC/PC connectors to meet different cabling and testing needs.
Compact package with standard pinout enables seamless integration into optical modules, test instruments, optical network equipment, and automated test platforms, ideal for high-density rack and automated production line installation.
working Principle
The 1x2 PM Mechanical Optical Switch controls its internal mechanical structure via electrical control signals,
rapidly switching between two states to achieve bidirectional selection of one input signal between two channels,
while maintaining the polarization state of the optical signal stably throughout the process,
providing a reliable optical path scheduling solution for polarization-sensitive systems.
Stage A
Common port P1 is connected to channel port P2, while P3 is disconnected. Optical signals input from P1 are directly transmitted to P2, completing optical path selection.
Stage B
Common port P1 is connected to channel port P3, while P2 is disconnected. Optical signals input from P1 are switched to P3, achieving channel switching.
