Precautions for using fiber optic patch cords

The optical modules at both ends of the fiber optic patch cord must be the same wavelength of transmission and reception, which means that both ends of the fiber must be the same wavelength of the optical module, a simple way to distinguish is the color of the optical module to be the same. In general, short-wave optical modules use multimode fiber (orange fiber), and long-wave optical modules use single-mode fiber (yellow fiber), to ensure the accuracy of data transmission.

　　Do not overbend and loop the fiber in use, as this will increase the attenuation of light in the transmission process. Care should be taken to ensure that the cable is not damaged during installation, maintenance or repair work.
　　Be sure to protect the fiber optic splice with a protective sleeve after the fiber optic patch cord is used, dust and oil can damage the fiber optic coupling.
　　If the fiber optic splice is soiled, you can use a cotton swab dipped in alcohol to clean it, otherwise it will affect the quality of communication.
　　1, before use, the fiber optic patch cord ceramic insert and insert end face must be wiped clean with alcohol and degreasing cotton.
　　2, the use of fiber optic minimum bending radius of not less than 150mm.
　　3, protect the core and core end face to prevent bruising, pollution, disassembly and promptly put on the dust cap.
　　4, laser signal transmission, please do not look directly at the end of the fiber.
　　5, there are man-made and other irresistible factors damage should be timely replacement of damaged fiber patch cord.
　　6, installation should be carefully read the manual before installation, and installation and commissioning under the guidance of the manufacturer or distributor's engineers.
　　7, fiber optic network or system anomalies, you can use the troubleshooting method to test one by one. Testing or troubleshooting jumper failure can be done first through and through test, you can usually use a visible laser pointer to light the entire fiber optic link to determine. Or further use the precision fiber optic insertion loss back loss meter, test its indicators, indicators within the qualified range, the jumper indicates normal, and vice versa is not qualified.
