Product Description

Product Description

The Kerns Technology Compact In-line Polarizer is a miniaturized fiber optic component designed to convert unpolarized or randomly polarized light into stable linear polarization, while maintaining low signal loss. It supports key wavelengths (1550/1310/1064nm) and features an ultra-compact package (φ3.0×30mm/φ3.2×30mm), making it ideal for space-constrained polarization-sensitive systems.
Available in SM→SM, SM→PM, or PM→PM fiber configurations, this polarizer delivers industry-leading performance: typical insertion loss as low as 0.3dB, extinction ratio ≥28dB, and 300mW CW power handling. Its wide operating temperature (-5~+70°C) and flexible connector options ensure compatibility with diverse communication, sensing, and research applications.

Product Features

1. Ultra-Compact Form Factor

Package size as small as φ3.0×30mm—enables integration into miniaturized devices (e.g., portable test equipment, compact fiber sensors) where standard-sized polarizers cannot fit.

2. High Polarization Performance

  • Typical extinction ratio: 30dB (min ≥28dB) ensures high-quality linear polarization conversion, critical for coherent systems and precision sensing.

  • Low insertion loss: 0.3dB (max 0.5dB) minimizes signal attenuation, preserving system efficiency.

3. Flexible Fiber Compatibility

Supports SM→SM, SM→PM, or PM→PM fiber combinations—adapts to both non-polarized and polarization-maintaining (PM) system interfaces.

4. Robust & Reliable

  • 300mW CW power handling meets low-to-medium power system demands.

  • Wide operating temperature (-5~+70°C) and high tensile load (5N) ensure stability in industrial and research environments.

Product Applications

This compact in-line polarizer is widely used in:

  • Coherent Communication Systems: Converts unpolarized signals to linear polarization for high-speed 1550nm telecom links.

  • Compact Fiber Sensors: Provides stable polarization for miniaturized current, strain, or gyro sensors.

  • Portable Test Equipment: Fits into handheld optical analyzers and laser characterization tools.

  • Scientific Research: Supports polarization-sensitive experiments in photonics, quantum optics, and spectroscopy.

FAQs

Q1: What is the role of an in-line polarizer?

A1: It converts unpolarized/randomly polarized light into stable linear polarization, which is essential for polarization-sensitive systems (e.g., coherent telecom, fiber gyroscopes) where consistent polarization state is required.

Q2: How do connectors affect performance?

A2: With connectors, insertion loss increases by 0.3dB, return loss decreases by 5dB, and extinction ratio drops by 2dB. We align connectors to the fiber slow axis to minimize polarization degradation.

Q3: Can I choose the fiber configuration?

A3: Yes. SM→SM suits non-PM systems, SM→PM connects non-PM sources to PM systems, and PM→PM supports fully polarized setups—all configurations are customizable.

Q4: Is this polarizer suitable for high-power applications?

A4: It supports 300mW CW power (standard) — ideal for low-to-medium power systems. For higher power needs, we offer customized high-power compact in-line polarizers.
