1×N PM PLC Splitter Selection: How PM Architecture Ensures Stable Power Distribution in Polarization-Sensitive Systems

1×N PM PLC Splitter Selection: How PM Architecture Ensures Stable Power Distribution in Polarization-Sensitive Systems

2026-05-09

1. Power Distribution Pain Points in Polarization-Sensitive Systems


In polarization-maintaining optical paths such as fiber amplifiers, power monitoring, and fiber optical instruments, standard splitters destroy polarization state, cause high insertion loss, uneven splitting, and return reflection interference, leading to higher system noise, signal distortion, and degraded long-term consistency. For industrial and test applications requiring strict polarization maintenance, 1×N PM PLC splitters with low loss, high extinction ratio, and high uniformity are critical for stable power distribution.

2. Product Positioning of 1×N PM PLC Splitter


Gezhi Photonics 1×N Polarization Maintaining PLC Splitter is based on planar lightwave circuit technology, supporting 1310nm/1550nm dual bands, offering full configurations from 1×2, 1×4, 1×8, 1×16, 1×32 to 1×64, with both-axis operation. Designed for polarization-sensitive systems, it features low insertion loss, high return loss, high directivity, and high uniformity to realize equal power splitting and stable polarization retention, ideal for optical amplification, signal monitoring, and fiber instrument integration.

3. Key Performance Parameters (Data-Supported)


  • Operating wavelength: 1310nm / 1550nm, range ±10nm
  • Insertion loss: 1×2≤3.8dB, 1×4≤7.0dB, 1×8≤10.2dB, 1×32≤16.6dB, 1×64≤21dB
  • Uniformity: max ≤0.3dB (1×2), up to ≤1.5dB (1×64)
  • Extinction ratio: ≥20dB (1×2–1×4), ≥18dB (1×8–1×32), ≥16dB (1×64)
  • Return loss ≥50dB, directivity ≥55dB, equal splitting ratio
  • Power handling: 500mW CW, operating temperature -5~+75℃
  • Packages: bare fiber, 900um tube, mini module, ABS box available

4. Selection Guidelines & Deployment Value


Prioritize configuration count, wavelength, package size, and connectors. This PM PLC splitter series enables stable splitting without compromising polarization, improving SNR and long-term reliability. Compact packages (down to 40×4×4mm) fit high-density integration. Standard FC/APC, SC/APC connectors simplify integration, widely used in fiber amplifiers, power monitoring, and PM test equipment.
