High Precision Polarization Maintaining Fiber Optic Patch Cord , PM Fiber Patchcord

Features: Extreme polarization extinction ratio (ER ≥ 23 dB) and precise axial alignment.

Pain points/value addressed: At 980 nm, 1064 nm, 1310 nm, 1480 nm, and the core 1550 nm bands, the polarization extinction ratio (ER) is ≥ 23 dB at 23°C (≥ 22 dB at 850 nm). In the manufacturing process, the key orientation is precisely aligned to the slow axis by default, and the optical axis alignment tolerance is strictly controlled within +3°. This industrial-grade polarization control completely eliminates measurement errors caused by polarization mode dispersion, ensuring that coherent equipment receives the purest linearly polarized light.

Features: Ultra-low insertion loss (≤0.3 dB) and high return loss protection address key concerns/values: For the 1310/1480/1550 nm bands, the jumper's insertion loss is an astonishing ≤0.3 dB (≤0.5 dB for 980/1064 nm and ≤0.8 dB for 850 nm). Combined with excellent return loss performance of ≥50 dB for the UPC endface and ≥55 dB for the APC endface, it significantly reduces potential damage to fragile laser sources caused by back-reflected light, saving crucial power budget for high-gain optical paths.

Features: Flexible working axis customization (Slow / Fast Axis)

addresses pain points and provides value: In addition to the industry-standard slow axis (SA) working mode, we also support fast axis (FA) customization based on the customer's specific optical path architecture. This provides optical system engineers with maximized physical layer matching freedom when designing complex polarization-maintaining interferometers or sensor networks.

Features: Exceptional industrial-grade environmental stability

addresses key pain points and provides value: The product supports continuous and stable operation at temperatures ranging from -5°C to +70°C, with an even wider storage temperature range of -40°C to +80°C. Its outstanding resistance to temperature drift and mechanical fatigue makes it perfectly suited for industrial testing environments with drastic temperature differences and the internal spaces of highly heated equipment.
