  • PLS-100

Polarized Light Source

  • Large polarization extinction ratio, up to 45 dB (typ.)
  • High output power >0dBm
  • Excellent power stability <0.1dB/h
  • Wavelength range 1310 ± 20 nm or 1550 ± 20 nm
PLS 100


The PLS-100 is a light source with well defined polarization. It features stable, high output power while maintaining a high polarization extinction ratio (PER) of 45 dB (typ.). Combining PLS-100 and PEM-340 (Polarization Extinction Ratio Meter) provides an optimized system for PER measurement of polarization maintaining (PM) fiber optic devices in both R&D and production environments.

High PER
PER up to 45 dB
High Power Stability
Output power > 0 dBm and Stability of < 0.1dB over 1 hour
Adjustable Polarization Axis
Output polarization adjustable between 0 and 180 degrees
