Optical fiber jumper (also known as optical fiber connector) means that both ends of the optical cable are installed with connector plugs to achieve optical active connection; One end with a plug is called a fiber pigtail.
Optical fiber jumper is used to connect the device to the optical fiber wiring link. With a thick protective layer, it is generally used in the connection between the optical end machine and the terminal box.
Pigtail is also called pigtail wire, only one end has a connector, and the other end is a broken end of a fiber optic cable core, connected with other fiber optic cable core by welding, often appears in the fiber optic terminal box, used to connect the fiber optic cable and the fiber optic transceiver (between the coupler, jumper, etc.).
The optical fiber connector is a detachable (active) connection device between the optical fiber and the optical fiber, which is the precision docking of the two end faces of the optical fiber, so that the light energy output of the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and minimize the impact on the system due to its involvement in the optical link, which is the basic requirement of the optical fiber connector. To a certain extent, optical fiber connectors also affect the reliability and performance of the optical transmission system.
Optical Fiber Patch Cord/Cable is similar to coaxial cable, except that there is no mesh shield. At the center is a glass core through which light travels.
In a multimode fiber, the diameter of the core is 50μm to 65μm, roughly the thickness of a human hair. The diameter of the single-mode fiber core is 8μm~10μm. The core is surrounded by a glass envelope 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.
