Fiber Closure Manufacturers Share Three Fiber Connections

Date:30-05-2019

Today, Fiber Closure   manufacturers share three common ways to connect fiber optics:

1. Fusion machine connection method. This method is used for cable breakpoint connections. Use a fiber fusion splicer (single-core fusion and ribbon fiber fusion splicer) to connect the fiber cores into one. The advantage is that the splice point loss is very small, mostly within 0.02 db. It is not easy to fail after welding. But the cost is higher.

2. Use the coupler connection method after the manual end. Manually end-to-end (using hand-grinding to make the head and then using the cold-stitched end and cutting with a cutter and then cold-bonding into the end), and then connected with a coupler. The advantage is lower cost, only the price of cold joints and extremely low labor costs. The disadvantage is that the attenuation is large (especially manual grinding, but this method has been eliminated), the coupler must be used, it takes a long time, and it is not suitable for the outdoor end. Therefore, most of the user end-ends for fiber-optic access are now available.

3. After the fusion splicer is connected to the end, the coupler connection method is used. This method is used for fiber jumpers. Use a fusion splicer to fuse the fiber to the jumper, and then use a coupler and fiber jumper to jump to other jumpers or equipment. The advantage is that it is convenient to maintain the split line. The disadvantage is that the attenuation is greater than the direct fiber splice connection. Mostly used in computer rooms, outdoor jumpers, etc.
