There are three main types of fiber jumpers according to the termination type: ST-ST, SC-SC, ST-SC. According to the type of fiber, there are mainly two types of single-mode fiber and multi-mode fiber. The specifications of the jumper length are 0.5m, 1m, 2m, 3m, 5m, 10m and so on. According to the cable outer sheath material, it can be divided into ordinary type, ordinary flame-retardant type, low-smoke halogen-free type, low-smoke halogen-free flame-retardant type, etc.

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

2. The transceiver wavelengths of the optical modules at both ends of the fiber jumper must be the same, that is to say, the two ends of the optical fiber must be optical modules with the same wavelength. The simple way to distinguish is that the colors of the optical modules should be the same.

3. After the optical fiber jumper is used, it is necessary to protect the optical fiber connector with a protective sleeve. Dust and oil pollution will damage the coupling of the optical fiber.
