Precision in Polarization: Enabling Advanced Optical Systems
In high-performance optical systems, from quantum communications to fiber optic gyroscopes, maintaining precise control over the polarization state of light is fundamental. Shenzhen Feiyi Optoelectronic Communication Co., Ltd. designs and manufactures the critical Polarization-Maintaining (PM) components that form the reliable backbone for these demanding applications.
We focus on engineering PM solutions where performance cannot be compromised. Below is a focused comparison of two core product lines that address distinct system-level challenges.
| Feature | PM MPO-MTP Patch Cords | PM Variable Optical Attenuators (VOAs) |
|---|---|---|
| Core Function | Provides high-density, multi-channel optical connectivity while preserving polarization alignment across every fiber in the array. | Delivers dynamic, precise optical power control without altering the polarization state of the signal. |
| Key Challenge Solved | Prevents polarization scrambling and crosstalk in space-constrained, high-fiber-count links used in coherent systems and advanced sensing. | Enables safe power leveling and receiver protection in PM systems where standard attenuation introduces polarization noise. |
| Critical Specifications | Precise slow-axis alignment per fiber, low insertion loss, high return loss, and robust mechanical reliability for repeated mating. | Exceptionally low Polarization-Dependent Loss (PDL), fast response time, high stability, and broad wavelength range. |
| Ideal Application Context | Interconnecting polarization-sensitive transceivers, building FOG sensing coils, and deploying QKD systems requiring multi-fiber, stable polarization links. | Balancing channel power in PM fiber networks, protecting sensitive detectors, and simulating real-world signal loss in laboratory test setups. |
