1. Try to use uniform batches of high-quality brand-name fiber optic splice closure on one line
Regarding the same batch of optical fibers, the mode field diameter is basically the same. After the fiber is disconnected at a certain point, the mode field diameter between the two ends can be regarded as the same. impact is minimized. Therefore, the optical cable manufacturers are required to use the same batch of bare fibers, continue to produce according to the required length of the optical cable, number each reel sequentially and distinguish the A and B ends, and do not skip numbers. When laying optical cables, they must be laid out along the determined routing order according to the number, and ensure that the B end of the front optical cable is connected to the A end of the next optical cable, and then ensure that the welding can be welded at the disconnection point during welding, and the fusion loss value reaches minimum.

Description:
Optical Splice Closures Are Used To Distribute, Splice, And Store The Outdoor Optical Cables Which Enter And Exit From The Ends Of The Closure. There Are Two Connection Ways: Direct Connection And Splitting Connection. They Are Applicable To Situations Such As Overhead, Man-Well Of Pipeline, Embedded Situation Etc. Comparing With Terminal Box,The Closure Requires Much Stricter Requirement Of Seal. Sealing Ring And Air Valve Are Required For Closure, But That Are Not Necessary For Terminal Box.
2. Optical cable erection is carried out as required
In the process of laying the optical cable, it is strictly forbidden to make small circles, folds and twists of the optical cable. More than 80 people must be employed for the construction of the 3km optical fiber, and more than 100 people must be employed for the construction of the 4km optical fiber, and 6 to 8 walkie-talkies must be equipped. The traction force does not exceed 80% of the weight of the optical cable, and the instantaneous maximum traction force does not exceed 100%. The traction force should be added to the reinforcement of the optical cable. The laying of optical cables should strictly follow the requirements of optical cable construction, and then minimize the probability of optical fiber damage during optical cable construction, and prevent the increase of fusion loss caused by optical fiber core damage.
3. Select experienced and well-trained optical fiber fusion splicing personnel for fusion splicing
At present, most of the fusion splicing is automatic fusion splicing machine, but the level of splicing personnel directly affects the size of splicing loss. Splicing personnel should perform splicing in strict accordance with the flow chart of the optical fiber fusion splicing process, and during the splicing process, they should use OTDR to test the splice loss of the splice point while splicing. Those that do not meet the requirements should be re-spliced. For points with large splice loss values, it is advisable to repeat the splice times 3 to 4 times. When the splice losses of multiple optical fibers are large, a section of the optical cable can be cut off and spliced again.
