GracyFiber’s PM MT-MPO Ribbon Assembly is a high-density, multi-core polarization-maintaining fiber solution designed for stable linear polarization transmission in compact photonic systems. Available in 8F, 12F, and 16F configurations, it supports a wide wavelength range from 405 nm to 1550 nm, covering visible, near-infrared, and telecom bands.
Built with precision-aligned PM fibers (PM405 to PM1550 series), the assembly ensures low insertion loss, high extinction ratio, and reliable multi-channel performance. With MT-based high-precision ferrules and flexible MT-FA / MT-MT / MT-MPO / MPO-MPO interfaces, it is ideal for advanced optical modules, quantum systems, laser delivery, and silicon photonics packaging where polarization stability and channel density are critical.
