What are the precautions for fiber splicing? How is fiber splicing aligned?

First of all, you must have a good fusion splicer, and secondly, the angle of cutting the optical fiber should be flat, pay attention to cleaning, and the optical fiber should be placed flat.

When using an optical fiber fusion splicer for optical fiber splicing, the failure to align is generally a method problem, please refer to the following method to complete the splicing.

The process and steps of optical fiber splicing of CIC optical fiber fusion splicer:

1) Strip the fiber optic cable and fix the fiber optic cable to the fiber rack.

Common optical cables include stranded cables, skeleton cables and central bundle tube optical cables, different optical cables should adopt different stripping methods, and the optical cables should be fixed to the coil fiber frame after stripping.

2) Fiber splitting passes the fiber through the heat shrink tubing. Separate the fibers of different bundles and colors and pass them through the heat shrink tubing. After the splicing is complete, the fiber optic fusion splices can be protected with heat shrink tubing.

3) Turn on the power of the fusion splicer and select the appropriate welding method. There are two kinds of power supply of the fusion splicer: AC and DC, which should be switched and switched reasonably according to the type of power supply. We know that the optical fibers used in CATV include conventional single-mode fibers and dispersion shift single-mode bright-mode fibers, and the working wavelengths are also 1310nm and 1550nm, so we need to choose the appropriate fusion splicing method according to the optical fibers and working wavelengths used by the system.

4) Preparation of optical fiber endfaces. The quality of the optical fiber endface will directly affect the quality of the splicing, so before splicing, it is necessary to make a qualified endface first. Use a special stripping tool to peel off the coating layer, and then use a clean linen cloth or cotton soaked in alcohol to wipe the bare fiber several times, use a precision optical fiber cutting knife to cut the optical fiber, and coat the optical fiber, the cutting length is 8mm-16mm, and the external coating) optical fiber, the cutting length can only be 16mm.

5) Place the optical fiber of the guessing hall. Place the optical fiber in the V-shaped groove carrying mega width of the fusion splicer, carefully press the optical fiber pressing plate and optical fiber clamp, set the position of the optical fiber in the pressing plate according to the optical fiber cutting length, and correctly place it in the draft shield.

6) Splice the optical fiber. After pressing the splice button, the optical fiber moves in opposite directions, and in the process of moving, a short discharge is generated to clean the surface of the optical fiber, and when the gap between the end faces of the optical fiber is suitable, the fusion splicer stops moving in the opposite direction, sets the initial gap, the fusion splicer measures it, and displays the cutting angle. After the initial gap setting is complete, the core or cladding alignment is performed, then the fusion splicer reduces the gap (the final gap setting), the arc generated by the high-voltage discharge melts the left fiber into the right fiber, and finally the microprocessor calculates the loss and displays the value on the display.

If the estimated loss value is higher than expected, the discharge can be re-discharged, and the fusion splicer will still calculate the loss after the discharge.

7) Remove the fiber and reinforce it with a heater. Open the draft shield and store the welding data at the same time. These include:

Splice patterns, data, estimated losses, etc. Remove the fiber from the fusion splicer, place the heat shrink tubing in the center of the bare fiber, place it in a heater to heat, and then remove the fiber from the heater. When operating, do not touch the ceramic part of the heat shrink tubing and heater due to the high temperature.

8) Coiled and fixed. Attach the connected optical fiber tray to the optical fiber receiving disk, fix the optical fiber, the receiving disk, the splice closure box, and the terminal box, etc., and complete the optical fiber splicing.

Optical fiber splicing procedure (check whether the optical fiber and device model match).

1. Stripping of optical fibers, according to the estimated length of optical fibers, peel off the outer skin of the optical fiber, expose the inner core, and pay attention not to damage the inner core of the optical fiber.

2. The optical fiber cable is installed and fixed, after the optical fiber is stripped off, the optical fiber is fixed with a splice box, and the optical fiber is surrounded and fixed in the optical fiber containment box to prevent the optical fiber from loosening.

3. Clean the inner core of the optical fiber, and install the fixed hose before stripping off the innermost protective sleeve of the optical fiber. The fiber optic glass filament needs to be cleaned with alcohol prior to splicing, cleaning each small fiber.

4. To cut the optical fiber, wipe the optical fiber head and the special cutter clean before cutting, and then the cutting incision should be neat, and then clean the mold silver.

5. Optical fiber splicing, put the two cut optical fiber heads to be welded in the machine, check whether the optical fiber cross-section is flat, and after confirmation, open the bad code and return to the beginning of the splicing.

6. Check the effect, check the loss of the optical fiber after fiber melting, and you can also check the light.
