In the field of communications, fiber optic transmission with transmission bandwidth communication capacity, low loss, resistant to electromagnetic interference, the cable diameter is small, light-weight, plus a rich way to obtain garbage, etc. Thus, lately, optical fiber communication in many fields has been popular. Produce light in the fiber transmission loss, this loss is principally consists of the transmission lack of the fiber itself, and fiber optic connectors at the splice loss. Optic cable once ordered, determine the basic transmission loss in the fiber itself, fiber optic connectors on the splice loss as well as the fiber itself, and on-site construction. Due to reduce the splice loss of the optical fiber in the joint could be increased fiber repeater amplifies the transmission distance and decreasing the quantity of attenuation of the optical fiber link. Therefore, to improve the welding company's optical fiber to cut back the splice loss, it is very important now. Within this paper, fiber splicing technology is introduced.
Here will be the introduction of fiber splicing equipments. The very first equipment is Fiber Fusion Splicer. Fiber splicing machine is principally useful for the development and upkeep of optical communications, optical cable. Mainly depend on the production arc melting of the optical fiber, even though the utilization of a collimator principle gentle push toward attain the coupling of the fiber mode field. Plus a Fiber Cleaver is important too. Sometimes an Optical Fiber Aligner may be used on this work. Normally the fiber aligner is a precise V-slot fiber aligner. It's utilized to produce a temporary fiber link that facilitates OTDR and Optical Power Meter measurement. It features a light and power meter-based loss measurement and bare fiber reel testing for confirming transmission capability, they're always have good alignment and with low connection loss, and in addition easy to operate.
There are three steps of Fiber Splicing:
1.Preparation of the fiber end face: Preparation including stripping with the fiber end face covered, and also cut in three sessions. Qualified the fiber end face can be a the welding necessary condition, end face quality directly affects the weld quality, so naturally was a vital link in the entire procedure for manufacturing optical fiber, cutting, probably the most critical step.
2.Fiber welding: Based on the material and sort of fiber, create the main element parameters from the main melting current of the greatest pre-melting and some time and Fibre fed amount. (1)Discharge experiments: Before use should be placed in the weld environment for around 15 min, mainly in the placement and employ of the environment where the greater among the (winter), in line with the prevailing atmospheric pressure, temperature, humidity and other environmental conditions, re-setting the release voltage and position with the welding machine , along with adjust the V-groove drive reset, the welding machine automatically adjusted to meet the particular discharge conditions on work. (2)Fiber splicing: Adopted inside the construction from the high-precision automatic welding machine, it has X, Y, Z three-dimensional image processing technology and automatic adjustment function, you might want to splice fiber end face detection, location settings and fiber alignment. Fusion process also needs to promptly clean welding machine V-shaped groove, the electrode, the goal lens, welding rooms, etc., always observe the welding presence of air bubbles, too small, too thick, an on-line melting, separation as well as other undesirable phenomena. Imaginary melting phenomenon often times, whether fiber should check weld materials, model matching, cutter and welding machine dust pollution and check the electrode oxidation conditions, if there wasn't any problem, and really should be a proper boost in the welding current.
3.Fiber work: Disk fiber is a technology, but additionally a skill. Scientific disk fiber, can create a rational layout Fibre additional loss, withstand test of energy and harsh environments, and can steer clear of the squeeze caused by the phenomenon of fiber cut. The technique of the disc fiber: (1)First after the middle for both sides, i.e. after shrinking the sleeve first individually placed in the fixing grooves, then deal with both sides with the I-fiber. (2)To 1 end plate fiber, i.e. in the side with the optical fiber plate in the fixed heat-shrinkable tube, after which cope with the other side I fiber. (3)According to the actual situation, using a selection of graphical disk fiber flexibility, by more than the size of the fiber and the size the reserved space, circle, ellipse, many different graphical disk fiber, and take full advantage of the reserved disk space.
Fiber splice is really a meticulous work, mainly in the face making, welding, plate and fiber links, demands the operator to careful observation, consideration, and operating norms. In short, in the actual operation, there has to be a strict and meticulous work style, good at summing up, to be able to increase the operational skills, reduce losses, and comprehensively enhance the excellence of the fiber splice.
