The key reason for the poor insulation of the fiber optic to the ground is caused by water entering the fiber optic splice closure.The maintenance department often finds water in the fiber optic splice closure in the daily maintenance process. The fiber is soaked in water for a long time, which makes the coating layer fall off and the properties of the fiber optic change. This causes the fiber optic to be fragile and affects the normal use of the optical cable. The optical cable must be cut. To gradually replace fiber optic splice closure.
Do not use shelf life sealants, strictly control the transportation and laying quality of optical cables, and do not cause damage to the outer cable sheath; select the appropriate optic splice closure according to the laying method of the optical cable; the fiber optic splice closure is installed above the perennial water level and the terrain is relatively low. In high locations, avoid long-term soaking of water in the fiber optic splice closure; do not arrange rainy days for construction, especially the connection of optical cables; choose a good monitoring line for insulation purposes. The focus is on improving the responsibility and operational level of construction workers and improving the operating points of the manufacturers.
1. Unpacking. Use a clean and well-connected box to see if the appearance of the box is clean and there are no defects.
2. inventory attachments.Open the joint box and check all the mounting parts and materials of the joint box. Are all the fastening screws complete? Extra accessories in the splice box must be collected because other splice box attachments may be missing.
3.Clean box and fiber optic.Use toilet paper or alcohol cotton to clean the contact surface and glue surface of the two box bodies of the joint box, and clean the rubber surface of the cable. The dirty connector box and the water inlet connector box can be rinsed with water first. After drying, they must be cleaned with alcohol and cotton. Fingerprinted, greased rubber can be cleaned with clean alcohol cotton. Do not remove the protective paper until the closure is closed.
