In existing production technology, be first the PLC of packaged steel pipe to be fixed on steel pipe by AB glue to the inside of boxlike encapsulation box, then optical fiber penetrated in the blank pipe that diameter is 2.0mm, may have following problem like this:
1, AB glue is according to weight ratio 1:1, to be mixed with B glue by A glue, and it is solid that the ratio that is easy to mistake when preparation glue causes glue to be pasted not strongly.
2, in operating process, optical cable is easily stained with glue, and due to AB, the glue solidifies on optical cable, cannot wipe, and causes PLC rectangular box directly to be scrapped.
3, in traditional handicraft because optical fiber is wound directly around in rectangular box, likely cause the too small or distortion of fiber bending radius, thereby cause PLC optical property defective.
4, boxlike PLC making basic working procedure is: the naked fine test-envelope steel pipe-dish rectangular box-Jia connector-optical performance test of PLC debugging-PLC.Due to very hard after AB glue curing, if cause PLC bad when envelope steel pipe or dish rectangular box, do not detect at that time, follow-up being difficult to reprocessed.
5, in traditional handicraft owing to being loose coiling in rectangular box, when doing drop test, optical fiber rocks and causes optical fiber mixed and disorderly in box, thereby causes PLC optical property to exceed standard.
6, very firmly crisp after AB glue curing, when boxlike PLC is during from the high-altitude drop of 1.8 meters, very large of impulsive force, cause steel pipe and encapsulation box to come off, while again falling, steel pipe rocks, thereby causes steel pipe to pull optical fiber, finally causes IL converted quantity to be greater than 0.5dB or single fiber fracture.
