Summary of fiber splicing technology

In the concept of communications, fiber optic transmission with transmission bandwidth communication capacity, low loss, resistant to electromagnetic interference, the cable diameter is small, light weight, and a rich way to obtain recycleables, etc. Thus, lately, optical fiber communication in many fields may be traditionally used. Produce light inside the fiber transmission loss, this loss is primarily consists of the transmission loss in the fiber itself, and fiber optic connectors in the splice loss. Optic cable once ordered, determine the basic transmission lack of the fiber itself, fiber optic connectors at the splice loss as well as the fiber itself, and on-site construction. As a result of reduce the splice loss in the optical fiber at the joint can be increased fiber repeater amplifies the transmission distance and lowering the quantity of attenuation with the optical fiber link. Therefore, to enhance the welding company's optical fiber to reduce the splice loss, it is crucial now. In this paper, fiber splicing technologies are introduced.

Here may be the introduction of fiber splicing equipments. The initial products are Fiber Fusion Splicer. Fiber splicing machine is primarily employed for the construction and upkeep of optical communications, optical cable. Mainly rely on the release arc melting of these two optical fiber, as the utilization of a collimator principle gentle push toward reach the coupling of the fiber mode field. Along with a Fiber Cleaver is important too. Sometimes an Optical Fiber Aligner may be used in this work. The fiber aligner is really a precise V-slot fiber aligner. It really is accustomed to create a temporary fiber link that facilitates OTDR and Optical Power Meter measurement. It has a light source and power meter-based loss measurement and bare fiber reel testing for confirming transmission capability, they're also have good alignment with low connection loss, and in addition an easy task to operate.

There are three steps of Fiber Splicing:

1.Preparation with the fiber end face: Preparation including stripping with the fiber end face covered, and also cut in three sessions. Qualified the fiber end face is really a the welding necessary condition, end face quality directly affects the weld quality, so naturally was a vital link inside the entire technique of manufacturing optical fiber, cutting, one of the most critical step.

2.Fiber welding: In line with the material and kind of fiber, set up the key parameters with the main melting current of the greatest pre-melting and time and Fibre fed amount. (1)Discharge experiments: Before use should be put in the weld environment not less than 15 min, mainly in the placement and use of the environment in which the greater distinction between the (winter), according to the prevailing atmospheric pressure, temperature, humidity along with other environmental conditions, re-setting the discharge voltage and position of the welding machine, as well as adjust the V-groove drive reset, the welding machine automatically adjusted to meet the particular discharge conditions on work. (2)Fiber splicing: Adopted in the construction from the high-precision automatic welding machine, it's got X, Y, Z three-dimensional image processing technology and automatic adjustment function, you may want to splice fiber end face detection, location settings and fiber alignment. Fusion process should also promptly clean welding machine V-shaped groove, the electrode, the goal lens, welding rooms, etc., always notice the welding presence of air bubbles, too small, too thick, an online melting, separation and other undesirable phenomena. Imaginary melting phenomenon often times, whether fiber should check weld materials, model matching, cutter and welding machine dust pollution and appearance the electrode oxidation conditions, if there wasn't any problem, and may be an appropriate increase in the welding current.

3.Fiber work: Disk fiber is really a technology, but also an art form. Scientific disk fiber, can produce a rational layout Fibre additional loss, withstand test of your time and harsh environments, and can prevent the squeeze brought on by the phenomenon of fiber cut. The method of the disc fiber: (1)First after the middle on sides, i.e. after shrinking the sleeve first individually put into the fixing grooves, then deal with either side with the I-fiber. (2)To 1 end plate fiber, i.e. from your side with the optical fiber plate from your fixed heat-shrinkable tube, and then handle the other side I fiber. (3)Based on the actual situation, utilizing a selection of graphical disk fiber flexibility, by a lot more than the length of the fiber and the size of the reserved space, circle, ellipse, many different graphical disk fiber, and make best use of the reserved disk space.

Fiber splice can be a meticulous work, especially in the face making, welding, plate and fiber links, requires the operator to careful observation, careful consideration, and operating norms. Simply speaking, in the operation, there must be a strict and meticulous work style, proficient at summing up, in order to enhance the operational skills, reduce losses, and comprehensively improve the excellence of the fiber splice.
