This document outlines the specifications for a single-mode optical fiber and cable designed for use around the 1310 nm zero-dispersion wavelength, suitable for both the 1310 nm and 1550 nm regions, and compatible with analogue and digital transmission. Thorlabs offers Polarization-Maintaining (PM) Single Mode Fiber Optic Patch Cables with a variety of connector options, including FC/PC, FC/APC, and hybrid FC/PC to FC/APC cables. Other options include cables with high extinction ratio (ER), cables with heating wire, AR-coated patch cables. A single mode fiber optic cable is a high-performance transmission medium designed to carry light signals over long distances with minimal signal loss. Widely used in telecommunications, data centers, and enterprise networks, these cables are essential for high-speed internet, voice, and video. Our Corning ® Glass, multi-fiber trunk cables provide high density connections to patch panels, cassettes or cable harnesses. These cables utilize the Multifiber Termination Push-on (MTP) connector. It's a high-performance version of the older MPO and is fully compatible. It consists of various components, including twisted pair cables, fiber optic cables, and cable accessories.
