Caution:
Transceiver module wavelength of light must be the same at both ends of the fiber jumpers , that must be the same at both ends of the fiber wavelength optical module , a simple distinction is the color of the light module to be consistent . Under normal circumstances , shortwave optical module using multimode fiber ( orange fiber ) , long wavelength single-mode fiber module ( yellow fibers ) to ensure the accuracy of data transmission. One must be a ceramic ferrule and fiber jumpers ferrule end face wipe clean with alcohol and cotton wool before use . 2 , the use of optical fiber minimum bend radius of less than 30mm. 3 , ferrule and ferrule end face protection against bumps , pollution, dust caps to bring timely after the demolition . 4, Do not stare into the laser signal transmission of the fiber end face . 5 , there should be artificial , and other force majeure damage timely replacement of damaged fiber optic jumpers. 6 , should read the instructions carefully before installation , and installation and commissioning in the manufacturers or distributors of Engineers guidance. 7 Do not use excessive fiber bending and circling, this will increase the light attenuation in the transmission process. 8 , fiber jumpers must use protective sleeve after use fiber optic connector protected, dust and oil will damage the fiber coupling . 9 , if the fiber optic connectors are dirty , you can use a cotton swab dipped in alcohol to clean , otherwise it will affect the quality of communication . 10 , optical fiber network or system anomalies , troubleshooting method can be individually tested . You can do first off test when testing or exclusion jumper failure, usually visible laser pointer can be used to judge the entire fiber link polish . Or further use of precision optical fiber insertion loss, return loss meter, test its targets , indicators within the acceptable range , the jumper indicating normal , otherwise unqualified.
