The use of the most common method of fiber cleaver are basically the same:
1, stripping cable and the cable fixed to the pan fiber frame. Common optical cable are gysts, skeleton and central tube cable, different fiber optic cable to take different stripping methods, strip after good will cable fixed to a dish rack.
2, will strip away after the fiber through the heat shrinkable tube, respectively.Separate optical fiber for different tube, different color, through the heat shrinkable tube, respectively.
3, open the welding electrical source, choose the right means of welding.Common type optical fiber specifications are: SM dispersion of single-mode optical fiber displacement (ITU – T G. 652), the MM multimode fiber (ITU – T G. 651), the DS dispersion-shifted single-mode fiber (ITU – T G. 653), NZ non-zero dispersion-shifted fiber (ITU – T G. 655), BI bending resistant fiber (ITU – T G. 657), etc., according to the different fiber type to choose the right means of welding, and the latest optical fiber welding machine have the function of automatic identification of optical fiber, can automatically identify the various types of optical fiber.
4, preparation of optical fiber end face.Optical fiber end face of good or bad will directly affect the quality of welding, so must be preparation before welding qualified end face.With dedicated wire stripping tool strip coating layer, then use stained using alcohol to clean linen cloth or cotton on the bare fiber brush try several times, using precision fiber optic fiber cutting knife cutting, to 0.25 mm (coating) fiber, cutting length is 8 mm – 16 mm, to 0.9 mm (coating) fiber, cutting length can be only 16 mm.
5, place the optical fiber.Put fiber V groove welding machine, fiber board and fiber fixture on careful pressure, according to the fiber cutting length is set in the positions of the platen, and correctly into the wind cap.
6, in place of optical fiber.After press the continue button, the optical fiber phase moving, moving process, produce a short discharge clean surface of fiber, when the gap between the optical fiber end face right after welding machine stop moving, violent set initial gap, welding machine measurement, and display the cutting Angle.After completion of the initial gap setting, begin to execute the fiber core and cladding, and then reduce gap welding machine (the final clearance setting), electric arc of high voltage discharge in the fiber optical fusion on the left to the right, the microprocessor and numerical calculate loss displayed on the screen.If the wastage of the estimate value higher than expected, can press set key to discharge, discharge welding machine will be calculated after the loss.
7, take out the optical fiber reinforced fiber and heater melting point.Open the wind cap, fiber optics from the welding machine, and then moved to the location of the contact melting, heat shrinkable tube in the heater heating, heating after take out the optical fiber from the heater.Operation, because of the high temperature, do not touch the heat shrinkable tube and ceramic part of the heater.
8, pan fiber and fixed.Will be good optical disc into the fiber holding plate, fixed fiber, shelter plate, connector box, terminal box, etc., the operation is complete.
