The fiber optic splice closure, also known as the barrel, is used for the end of the fiber optic cable and then connected to the optical switch through a fiber jumper. It can resist the aging of materials caused by heat, cold, light, oxygen and microorganisms in nature, and has excellent mechanical strength. The consolidated fiber optic splice closure shell and main structural parts can endure the worst environmental changes and together, it is flame retardant. The waterproof effect makes the sensation, impact, cable tension, distortion and other maintenance. fiber optic splice closure features: 1. The box of the fiber optic splice closure is made of excellent engineering plastics. 2. The fiber optic splice closure uses 2 times of cable clamping technology to ensure no additional attenuation of the fiber in the box. 3. The fiber optic splice closure has multiple multiplexing and capacity expansion functions. 4. All of them use multiple stainless steel screws to fix the seal, which is the most reliable fiber optic splice closure at home and abroad. The fiber optic splice closure is suitable for the maintenance of various optical cable straight-through joints and branching joints, and can be used for burying, overhead, wall hanging and pipeline wall-mounting devices. The whole set of fiber optic splice closure plastic parts is made of scientifically formulated high-strength PC to form engineering plastics. It can effectively resist the aging of data caused by cold, heat, oxygen and ultraviolet rays in nature through the injection molding of numerical control equipment, and has excellent mechanical strength. The consolidated fiber optic splice closure shell and the main structural member can play the role of flame retardant, waterproof and shockproof, and together with the maintenance effect of stretching, flattening, impact, bending, twisting and axial tightening of the cable joint, and can -40 ° C - + 75 ° C long-term use in the natural environment. 5. The high-quality elastomer rubber sealing material is selected, and the mold is molded once, so that the fiber optic splice closure has no joint connection, the sealing function can be ensured, and the repeated repeated opening, repeated use, and the construction problem can be solved, and the fiber optic splice closure can be disassembled and assembled. It is quick and convenient, and it can accept the most intense temperature changes in nature for a long time, ensuring excellent sealing function.
