Analysis of the process and steps of fiber optic cable splicing


The fiber optic cable splicing connects the end of one fiber optic cable with the beginning of the next fiber optic cable to form the entire operation process of a continuous fiber optic cable line. Optical fiber splicing requires that the additional loss of the optical fiber connector is small, the reliability of the connector is high, it has good mechanical properties, and the characteristics are kept stable for a long time. The connection work must be carried out step by step to ensure the stability of the communication network.


Fiber Optic Cable Connection


Optical fiber splicing requires small additional loss of optical fiber splices, high reliability of the splices, good mechanical properties, and long-term stability of characteristics; on-site construction requires simple operation, short connection time, and low cost.

Be careful not to injure the bundle tube, take about 1m for the stripping length, wipe the ointment clean with toilet paper, and put the optical cable into the splice box. When fixing the steel wire, it must be pressed tightly without loosening. Otherwise, it may cause the fiber optic cable to roll and break the fiber core.


Separate the fibers of different bundles and colors and pass them through the heat-shrinkable tube. The stripped fiber is very fragile, use heat shrink tubing to protect the fiber splice.


Before splicing, a suitable splicing procedure should be selected according to the optical fiber and working wavelength used by the system. Unless there are special circumstances, the automatic welding procedure is generally used.


The quality of the fiber end face will directly affect the connection quality, so be sure to make a qualified end face before fusion splicing.


Open the draft shield, take the fiber out of the fusion splicer, place the heat shrink tube in the center of the bare fiber, and place it in a heating furnace for heating.


Coil the spliced ​​optical fiber onto the optical fiber receiving tray. When coiling the fiber, the larger the radius of the coil and the larger the radian, the smaller the loss of the entire line. Therefore, a certain radius must be maintained to avoid unnecessary losses when the laser is transmitted in the core.


The field connection box must be sealed to prevent water from entering.



ZR Cable reminds: The optical fiber splicing work is a relatively meticulous and precise work, and must be operated by professional staff to avoid unnecessary losses


After the optical fiber splicing work is completed, attention should also be paid to the sealing of the optical cable splice box to protect the optical fiber and ensure stable communication.
