Fiber Optic Splice Closure Connection Method


The whole set of Fiber Optic Splice Closure plastic parts adopts scientifically formulated high-strength PC synthetic engineering plastics. After injection molding by numerical control equipment, it can effectively prevent the aging of materials caused by cold, heat, oxygen and ultraviolet rays in nature, and has excellent mechanical strength. It is necessary to fix the fiber and the connection box of the fiber optic splice closure. What should we do? Let's take a look at it together!

The fiber cannot be circled in the disk, and the length of the fiber should be appropriate. If the fiber is small or the bending radius is too small, the optical signal loss will be large; if the length of the reserved fiber is too short, it will be difficult to maintain the welding difficulties. Too long will reduce the safety of the fiber. The length of the reserved fiber is generally Before the welding, the tray is 2~4 times in the tray. If you use the same type of tray for a long time, you can also measure the length that should be reserved.

The fiber connection is the most vulnerable place. If the external heat conduction shrinkage tube vibrates, the joint will break and the fiber on both sides of the heat shrinkable tube will be easily broken. Therefore, the heat shrinkable tube must be fixed in the tube holder, and be careful not to press on the fiber.

After the fiber optic disk is good, it is fixed by soft sticky adhesive paper. It is not suitable to use hard or poor quality adhesive tape such as double-sided tape. Otherwise, the adhesive tape will age and make the fiber loose, and the wind or external force will vibrate. When the fiber breaks or the loss becomes large.

Fiber optic splice closure fixed:

When the fiber optic splice closure is fixed, the most important thing to pay attention to is its tightness. When the cable is connected to the cover of the box, check whether it is sealed. Pay special attention to the sealing at the entrance of the cable. It is best to use a glue at each port.

After the fiber optical is fixed, the two optical cables should be wound several times and fastened. If the optical cable on the side of the fiber optic splice closure is straightened, due to the thermal expansion and contraction, the inner tube of the box is separated from the tray or even retracted into the outer sheath of the optical cable. Causes the fiber to break.
