OZ Optics Polarized Fiber Optic Source 980 nm FC/PC (PFOSS Series)

The OZ Optics Polarized Fiber Optic Source (PFOSS Series), 980 nm FC/PC, is a high-stability polarized laser source designed for precision polarization-sensitive testing in fiber-optic component characterization and system verification. It provides a high polarization extinction ratio (up to 40 dB) along with stable output power, supporting accurate extinction-ratio measurements, PDL testing, and manufacturing QA procedures. The PFOSS platform is offered in multiple configurations, including receptacle-based units with fixed or rotatable polarizers, enabling users to align or adjust the polarization axis as required. It also supports options such as adjustable optical attenuation and high-power versions while maintaining consistent spectral properties during power changes. OZ Optics recommends angled connectors for maximum stability, especially in sensitive measurement setups. With its rugged, compact design and broad wavelength availability—covering 980 nm through other key telecom bands—the PFOSS series provides a dependable polarized source for both laboratory and production environments.
