As for the fiber optic patch cord, it is used to make the patch cord from the equipment to the fiber optic cabling link. There is a thicker protective layer, which is generally used for the connection between the optical transceiver and the terminal box. Fiber patch cords are similar to coaxial cables, but without the mesh shield. At the center is the glass core where light travels. In a multimode fiber, the diameter of the core is 15 μm to 50 μm, which is 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 in the core. On the outside is a thin plastic jacket that protects the envelope.

Will the jumper be as permanent as the circuit and will be aging and attenuated? In fact, if you understand the structure of the fiber jumper, there will be no such doubts. In the middle is the fiber core, and then the outside is the glass envelope, and there is a layer of plastic cover It has a protective effect on the outside. Over time, the outer plastic jacket will age. After the protective layer is damaged, the propagation rate of the jumper will naturally decrease.

There are several points to pay attention to in the use of optical fibers:

1. After using the optical fiber jumper, be sure to protect the optical fiber connector with a protective sleeve. Dust and oil will damage the coupling of the optical fiber.

2. Do not bend and loop excessively during use, which will increase the attenuation of light during transmission.

3. If the optical fiber connector is dirty, you can use a cotton swab dipped in alcohol to clean it, otherwise it will affect the communication quality.
