Optical Patch Cord is widely used nowadays, the patch cord is a weak link in the network optical fiber infrastructure. So in order to achieve the best performance and reliability, we must follow the correct procedures in the optical patch cord managing center. Following list some problems which should be noticed during using the optical patch cord:

※ The wavelength of optical module on both ends of patch cord must be same.

※ To ensure the accuracy of the data transmission, the short wave module generally uses multimode optical fibers (usually orange), and the long wave module uses single mode optical fiber (usually yellow),

※ Don’t make the optical fiber in excessive bending and winding when using it, this will increase the attenuation of light in the transmission process. The minimum bending radius of optical fiber is less than 30mm when using.

※ To protect the fiber connector and avoid the dust and oil pollution damage the coupling of fiber, we must use the protective sleeve after using the patch cord.

※ If the fiber connector is dirty, we can use the absolute alcohol to clean, or it will affect the quality of communication.

※ We must use the alcohol and cotton to clean the ceramic ferrule and the interface of the patch cord before using.

※ To avoid being damaged and polluted, Please protect the ceramic ferrule and the interface, fitted with dust cap after disassembling.

※ Don’t look directly at the optical interface when the laser signal is transmitting.

※ We should timely change the damaged patch cord when having the human or other non - Anti - factors damages.

※ Reading the instructions carefully before installation, installing and debugging under the guidance of the manufacturer or dealer's engineers.

※ If the fiber network or system is abnormal, we can use the fault elimination method to test one by one.

※ We can make on-off test first when testing or excluding patch cord fault, usually using red pen to polishing and judging the fiber link.

※ Or using precision optical fiber insertion loss and return loss tester, testing its various indicators. If Indicators in the qualified range, then the patch cord indicated normally, otherwise unqualified.

Above are some attention problems when using patch cord , we have to remember and use it reasonably. Hope you will pay more attention in future use after read this blog.
