Fiber optic patch cords are fiber optic cables with fiber optic connectors at both ends. They are used to connect optical signals between devices and are one of the most basic passive components in optical communication systems. Assembled fiber optic patch cords are finished patch cords that are assembled by manual or automated processes using optical fibers, connectors, protective covers and other components.
Manufacturing process features
1. Precision assembly process
Fiber stripping: remove the fiber coating and retain the bare fiber.
Cleaning and cutting: wipe the bare fiber with alcohol and prepare a flat end face with a fiber cleaver.
2. Crimping/fusion:
Crimp: insert the bare fiber into the connector ferrule and complete the connection by epoxy resin curing and grinding.
Fusion: use a fiber fusion splicer to fuse the bare fiber with the connector pigtail, which has lower loss, but requires professional equipment.
3. Grinding and polishing: use sandpaper or a grinder to grind the connector end face in multiple stages, and finally polish it to a mirror effect to ensure good optical contact.
4. Automation and standardization
High-end patch cord production uses automated equipment (such as automatic fiber stripping machines, grinders, and end face detectors) to ensure consistency.
Advantages
1. Plug and play, easy installation and maintenance
2. Support high bandwidth
3. Small size, saving wiring space
4. Anti-electromagnetic interference, suitable for harsh environments
