Custom Polarization-Maintaining (PM) Fiber Patch Cords – Precision Connectivity for Demanding Applications
Our Polarization-Maintaining (PM) Fiber Patch Cords are engineered to deliver exceptional performance in applications requiring stable polarization states. Designed with compact ceramic ferrule connectors, these patch cords ensure low insertion loss, high return loss, and excellent mechanical durability. They are ideal for telecommunications, CATV, FTTH, LAN, fiber optic sensing, and high-precision test equipment.
Available in a wide range of wavelengths—including PM630, PM780, PM850, PM980, PM1064, PM1310, and PM1550—these patch cords support precise polarization alignment and can be fully customized. Choose from connector types such as FC, SC, LC, ST, MU, or MTRJ, and select your preferred boot colors and cable lengths to meet specific system requirements.
Trust our PM fiber patch cords for reliable, high-density connectivity and tailored solutions that fit your unique optical integration needs.
