Fiber optic jumper at both ends of the optical transceiver transceiver wavelength must be consistent, that is, both ends of the fiber must be the same wavelength of the optical module, a simple distinction is the color of the optical module to be consistent. In general, shortwave optical modules use multimode fiber (orange fiber), long-wave optical module using single-mode fiber (yellow fiber) to ensure the accuracy of data transmission.
1, the optical fiber in the use of not excessive bending and winding, this will increase the attenuation of light in the transmission process.
2, if the fiber connector is dirty, you can use cotton swab dipped in alcohol to clean, otherwise it will affect the communication quality.
3, after the use of fiber optic jumpers must use protective cover to protect the fiber connector, dust and oil pollution will damage the fiber.
4, when used, the minimum bending radius of the fiber is not small 150mm.
5, must be used before the fiber jumper ceramic ferrule and ferrule end with alcohol and absorbent cotton wipe clean.
6, when the laser signal transmission do not look directly at the fiber end.
7, to protect the ferrule and ferrule end to prevent bruises, pollution, after the demolition of a timely dust cap.
8, before installation should carefully read the instructions, and manufacturers or distributors under the guidance of engineers to install debugging.
9, the emergence of man-made and other non-damaging factors should be replaced when the damaged fiber optic jumper.
10, optical fiber network or system anomalies, can be used to test one by one troubleshooting. Test or exclude jumper fault can be done first on-off test, you can usually use the visible laser pen on the entire fiber optic link to determine the light. Or further use of precision fiber insertion loss loss meter, test its indicators, indicators within the qualified range, the jumper indicates normal, and vice versa is not qualified.
