Multicore Polarization-Maintaining Armored Optical Cable
A tight-buffered, multicore PANDA-type polarization-maintaining (PM) fiber optic cable engineered for high-birefringence signal transmission in demanding field and industrial environments. Built with imported aramid yarn and a non-metallic central strength member for tensile reinforcement, then armored and jacketed for long-term outdoor, indoor, and duct installation. Ideal for fiber optic gyroscopes (FOG), coherent optical communication, distributed fiber sensing, EDFA/DWDM modules, and other polarization-sensitive photonic systems.
Product Description
The multicore polarization-maintaining armored optical cable utilizes multiple 900μm tight-buffered polarization-maintaining optical fibers as the transmission medium. It employs imported aramid fibers and non-metallic central strength members as tensile reinforcement elements. The cable core (comprising tight-buffered optical fibers, aramid, and non-metallic central strength members) is sequentially processed with inner sheathing, armoring, and outer sheathing.
As a fiber optic cable manufacturer specializing in special/specialty optical fibers, we engineer this PANDA polarization-maintaining armored cable to hold its polarization extinction ratio (PER) and low insertion loss under real-world tensile load, crush, and bending stress — not just in a lab datasheet. Every reel is tested at 1310 nm before shipment, and cable length, sheath material, and connector termination can be customized to your project's exact requirements.
