PolaELSFP-1000

ELSFP Polarization Extinction Ratio Test System

The CUBE-ER100-ELSFP Polarization Extinction Ratio (PER) Measurement Set is a high-accuracy test solution designed for high-power ELSFP and other narrow-linewidth laser modules with polarization-maintaining (PM) fiber outputs.

ELSFP lasers present a challenge for conventional polarimeters due to their narrow linewidth and long coherence length, imiting accuracy, repeatability, and confidence in polarization characterization.

The CUBE-ER100-ELSFP is purpose-built to deliver reliable and repeatable PER and polarization axis measurements under these challenging conditions.

Features

  • Optimized for ELSFP lasers with narrow linewidth

  • ccurate PER and polarization axis angle extraction at high PER

  • Supports high optical power up to 30 dBm

  • High-PER MT-FC test cable with low stress sensitivity

  • Automated software for measurement, logging, and analysis

  • Single-channel or parallel multi-channel configurations

Made In USA
Description

The system measures PER using a direct, rotating-polarizer method, avoiding wavelength-dependent Stokes reconstruction. To improve measurement reliability, the PM test fiber between the laser under test and the PER meter is thermally cycled, enabling stable and repeatable evaluation of PER and polarization axis behavior across operating conditions.

The system incorporates:

  • CUBE-ER100 high-dynamic-range PER meter, 

  • High-power optical attenuator - supporting input power levels up to 30 dBm,

  • High-PER MT-FC test cable,

  • Thermal cycling unit and automated test software for measurement control,

  • Data logging,

  • Visualization, and

  • Report export.

 

To match different throughput requirements, the system is available in

  • Single-meter configuration for sequential testing or a

  • Multi-meter parallel configuration for simultaneous multi-channel measurement, significantly reducing test time in production environments.​

The CUBE-ER100-ELSFP is ideal for R&D validation, reliability testing, incoming inspection, and high-volume manufacturing screening of ELSFP and other PM fiber-coupled laser modules.
