Splice should pay attention to several issues.

Splice should pay attention to several issues.

1 cable stripping knife into the depth of the attention. Cable outer sheath stripping is the key to mastering the knife into the sheath cutter depth, it will be very prone to broken fiber. In practice, you should rotate the sheath edge cutter, and observe the incision, if we see a white polyester belt, you should stop into the knife, remove the cutter. This step is a skilled process to be several times the depth of practice to master feed.


2 core cable with a fixed beam tube stripping. Cable stripping, the fiber-optic cable connector fixed on the box, stripping core beam tube, fiber splicing before doing all the preparations.


3 fiber splicing. Fiber connecting directly related to the project's quality and longevity, the key lies in the fiber end preparation. Fiber smooth, no glitches or defects, welding machines are well received confirmation, and can meet the engineering requirements to make the connection, if the fiber end face failure, welding machine refused to work or take a big loss of connection, not meet the engineering requirements. Fiber end in the production process, stripping out the first optical fiber coating, the wire stripper to the fiber axis vertical, to ensure that strippers do not scratch the fiber; in cutting optical fiber, to operate in strict accordance with procedures, the use of end-cutting knife cutting length to achieve accurate, fast action, clever hard to ensure that fiber is its breaking, rather than pressure off; in time to take fiber to ensure that fiber does not touch any object, to avoid face bumps, do out of the face is smooth, qualified. Optical fiber fusion splicing machine is the key equipment, but also a high degree of precision and expensive equipment. In the course must be in strict accordance with procedures to operate, or may cause significant losses. Of particular note is the welding machine's operating procedures, the length of heat shrink tube set and requirements should be consistent.


4 more than the protection of optical fiber splicing is completed, it is necessary to protect the fibers shrink tube, but also on the disk left over fiber.


5 connector box sealed in the actual project cable connector box sealing is very important. After the fiber optic connector box because the water surface is prone to micro-cracks, the fiber will break a long time, and the connector box which is the way buried in the ground in the majority, it must do the joints sealed box. Connector box seals, mainly cable and connector box, box joints between the upper and lower cover both parts of the seal. Conducting cable and connector box seal, first seal the cable sheath at the grinding work, with gauze on the outer sheath fiber axis vertical grinding to make the cable more tightly and seal with tape, seal better . Connector box cover seal between the upper and lower, main attention to the sealing tape to prevent the connector box evenly sealed tank, tighten the screws, without leaving gaps.
