Fiber optic patch cords are cable assemblies composed of optical fibers and connectors, primarily used for establishing physical connections between optical transceivers and fiber optic links. Their core function is to create data transmission channels between devices and fiber optic networks. Common applications include connecting optical transceivers to terminal boxes and adapting switch optical module interfaces. Based on transmission requirements, they are categorized into two main types: single-mode (suitable for long distances) and multi-mode (suitable for short distances). Connector interfaces include mainstream specifications such as LC/SC/MPO. Selection must match the device interface type and transmission medium parameters.
Structural Composition
Optical patch cords consist of an optical fiber cable with connectors at both ends. Precision ceramic ferrules enable physical alignment between the optical terminal interface and the fiber optic link.
Typical structure includes
Optical Fiber: Single-mode (9/125μm) or multi-mode (50/125μm/62.5μm)
Connectors: Duplex interfaces (e.g., LC/SC) or multi-fiber interfaces (e.g., MPO)
Protective Components: Metal ferrules, dust caps, bend-resistant jackets
