Gracyfiber’s PM MT-MPO Assembly is a pre-terminated multi-core fiber solution built with polarization-maintaining (PM) ribbon fiber and industry-standard MT/MPO connectors. Available in 8F, 12F, or 16F configurations, it supports wavelengths from 405 nm to 1550 nm — optimized for quantum systems, laser arrays, coherent telecom, and high-density sensing applications.
Each channel maintains strict polarization alignment (ER ≥15–22 dB), low insertion loss (≤1.6–4.1 dB depending on wavelength), and precise keying tolerance (±3°). With flexible connector options (MT-FA, MT-MT, MPO-MPO) and customizable lengths (0.1m–5m), this assembly enables rapid, reliable deployment of polarized multi-channel optical links — without manual splicing or alignment.
