Description
The Polarization Maintaining (PM) Fiber Patch Cable is engineered for high-precision optical applications requiring stable polarization control and minimal optical loss. Designed to meet Telcordia specifications, this cable utilizes high-quality Panda PM fiber and supports a wide range of industry-standard connectors, including FC/UPC, FC/APC, SC/UPC, SC/APC, LC/UPC, and LC/APC.
Spanning a broad wavelength range from 460 nm to 2000 nm, this cable delivers excellent performance in various photonic systems. It features low insertion loss—down to 0.2 dB typical at telecom wavelengths—and high extinction ratios of ≥20 dB (standard), ≥28 dB (high grade), and ≥30 dB upon request. The default configuration aligns the fiber's slow axis with the connector key, with fast axis alignment available as an option.
The cable is offered with multiple jacket types and customizable lengths, making it ideal for PM sensing systems, polarization-sensitive instrumentation, and other precision optical applications. Built for reliability, it ensures consistent operation across an extended temperature range from -5°C to +70°C, with tight polarization angle tolerances and excellent mechanical stability.
