KEXINT FC/UPC-FC/UPC LSZH 3.0MM Single Mode G657A1 Duplex 3M Fiber Optic Patch Cord

Fiber optic patch cord means that both ends of the optical cable are equipped with connector plugs to realize the active connection of the optical path; one end with a plug is called a pigtail. Fiber optic patch cords are similar to coaxial cables, but without the mesh shield. In the center is the glass core for light propagation. In a multimode fiber, the diameter of the core is 50 μm to 65 μm, roughly equivalent to the thickness of a human hair. The single-mode fiber core has a diameter of 9 μm. The core is surrounded by a glass jacket with a lower refractive index than the core to keep the fiber inside the core. On the outside is a thin plastic jacket to protect the envelope.
