Industrial-Grade PM Splitters: Compact 1×N PM PLC Modules for High-Density Optical Device Integration

Industrial-Grade PM Splitters: Compact 1×N PM PLC Modules for High-Density Optical Device Integration

2026-05-09

1. Two Key Pain Points in High-Density Integration


In polarization-maintaining fiber system integration, limited chassis space and rising multi-channel splitting demand expose weaknesses of traditional splitters: large size, temperature drift, poor polarization retention, and insufficient uniformity. These cause crowded cabling, poor heat dissipation, and lower stability, especially in portable and rack-mounted devices. Miniaturization, wide-temperature stability, and PM reliability become essential selection criteria.

2. Compact PM PLC Splitter Solution


Gezhi Photonics 1×N PM PLC Splitter features industrial-grade wide-temperature design and miniaturized packaging, maintaining stable optical specs from -5~+75℃. It supports bare fiber, 900um loose tube, mini module, and ABS box styles, with dimensions as small as 40×4×4mm, easily fitting high-density PCBs and compact chassis. It combines low insertion loss, high uniformity, and high polarization extinction ratio to deliver stable and reliable multi-channel PM power splitting.

3. Core Configurations & Industrial Reliability


This series supports 1310/1550nm wavelengths, covering 1×2 to 1×64 channels, with both-axis operation (non-blockable) and extinction ratio tested on slow axis. Return loss ≥50dB and directivity ≥55dB effectively suppress back-reflection interference. It withstands up to 500mW CW power, tensile load ≤5N, and storage temperature -40~+85℃, suitable for industrial installation and harsh environments. Connectorized versions add only 0.3dB IL, enabling quick deployment with standard interfaces.

4. Value for System Integration & Long-Term Operation


Compact packages greatly save rack and chassis space, improving integration density and heat dissipation. High uniformity ensures consistent power across output channels; high return loss protects lasers and amplifiers; high extinction ratio preserves polarized signal purity. Wide-temperature performance ensures 24/7 stability, reducing failure and maintenance costs. It is widely used in PM systems including optical communications, industrial lasers, fiber sensing, and precision test instruments.
