1. Product Overview
The PM Fiber Array is a key component for multi-channel polarization-maintaining optical path assembly. Unlike ordinary fiber arrays, the PM array uses panda-shaped polarization-maintaining fibers precisely assembled in a high-precision quartz or silicon V-groove substrate.
2. Product Advantages
High Extinction Ratio, Strong Multi-Channel Polarization Maintenance
The array utilizes 250 μm Panda PM fiber (Corning PM15-U25D) and optimized assembly processes. Depending on the number of channels, the typical extinction ratio range is approximately 15–25 dB:
- 1/2 Channels: ER ≥25 dB
- 4 Channels: ER ≥23 dB
- 8 Channels: ER ≥21 dB
- 16 Channels: ER ≥20 dB
- 32 Channels: ER ≥16 dB
- 64 Channels: ER ≥15 dB
Low Insertion Loss and Excellent Channel Consistency
Precise Polarization Axis Alignment for Simplified System Integration
Flexible Selection of Multiple Channels and Core Pitches
High Mechanical Stability and Environmental Reliability
3. Applications
- PM photonic waveguide devices (PM waveguides / PLC device coupling)
- PM collimator arrays / PM combiners
- Multi-PM fiber collimators
- Different laser sources
- Various polarization-sensitive coherent communication, photonic integration, and precision optical systems
FAQ
1. As an overseas optoelectronic equipment integrator making long-term purchases, are we eligible for tiered discounts?
Yes. We are committed to providing long-term professional supply chain support to high-end optoelectronic equipment manufacturers worldwide. For bulk purchases and annual framework cooperation agreements, your dedicated business team will calculate highly competitive B2B tiered ex-factory prices from source factories and provide comprehensive business support policies such as priority production scheduling and flexible inventory preparation, effectively optimizing your core optical component procurement costs.
2. How do you ensure that the extremely fragile high-density array end faces are protected from contamination and physical damage during cross-border logistics?
We have designed the highest level of industrial protection solutions for semiconductor-grade precision optical arrays. All multi-channel polished end faces are designed with suspended protection and covered with custom dust covers to completely isolate microparticle contamination. Each device, after standardized fiber optic cable management, is independently fixed in an anti-static blister box or high-density shock-absorbing pearl cotton, and then nested in a sturdy, thickened corrugated cardboard box. This complete solution completely eliminates mechanical vibration and stress damage during long-distance air or sea transport, ensuring that products arrive at your cleanroom perfectly undamaged.
