Definition and principle of optical fiber patch cord

• What is a fiber optic patch cable:

Optical Fiber Patch Cable, also known as fiber optic jumper, fiber optic patch cord or fiber optic cable, is a short-distance fiber optic cable used to connect fiber optic equipment. It is commonly used in fiber optic communications systems, data centers, computer networks, and other applications that require high-speed fiber optic connections.

Fiber optic jumper cables are composed of optical fiber core wires and protective layers. They usually use Single-Mode Fiber, SMF or Multi-Mode Fiber, MMF with a smaller diameter. These optical fiber core wires are connected to the optical fiber port of the device through special optical fiber connectors (such as SC, LC, ST, etc.) to realize the transmission of optical signals.

• Working principle of fiber optic patch cord:

1. Optical signal transmission: One end of the optical fiber jumper is connected to the optical fiber transmitting device, such as an optical fiber switch or optical fiber transmission equipment. When a device sends an optical signal, the optical signal is converted into light pulses and transmitted through the core of the fiber optic patch cord.

2. Fiber optic transmission: Optical signals are transmitted through the core of fiber optic patch cords. Optical fiber jumpers usually use single mode fiber (Single Mode Fiber, SMF) or multimode fiber (Multimode Fiber, MMF). During the transmission process, the optical signal propagates through the phenomenon of total reflection inside the optical fiber.

3. Optical signal reception: The other end of the fiber optic jumper is connected to the fiber optic receiving device, such as a fiber optic transceiver or fiber optic receiving module. When the optical signal reaches the receiving end, the optical fiber receiving equipment converts the optical signal into an electrical signal for subsequent processing and use.

4. Fiber optic connectors: Both ends of the fiber optic jumper are equipped with fiber optic connectors, such as SC, LC, ST and other types of connectors. These connectors are precisely designed and assembled to ensure proper alignment and connection of optical fibers to minimize loss and reflection of optical signals.
