Fiber Closure  Splicing is one way to join two optical fibers together so that the light signal from one optical fiber can be transferred into another optical fiber. A splice is a permanent connection of two optical fibers. Can be taken apart and put back together as they can if you join them using connectors. usually, splice is employed for one of three reasons: to repair a damaged cable, to extend the length of a cable, or to join two different cable types This article will introduce some useful knowledge about fiber optic splicing. Generally, there are two methods for fiber optic splicing: mechanical splicing and fusion splicing. （1）Mechanical Splicing This basically refers to alignment of devices by mechanical splices which have been designed in such a way that they are able to hold ends of two fibers in a position which is precisely aligned enabling light to be able to pass from one fiber to the other. With mechanical splicing you usually get a loss of 0.3 dB. （2）Fusion Splicing In fusion splicing there is machine (fusion splicer) which is used to align the ends of two fibers precisely, and then the two glass ends are welded or fused together by use of a heat or an electric arc. By effectively implementing the above you will be able to cut down on the loss of light transition thanks to the continuous connection which has been established between the fibers. Greentelftth supplies fiber optic splice closures with different ports types, fittings and fiber optic core numbers. These splice closures are made of excellent engineering plastics and suitable for protecting optical fiber splices in straight through and branching applications, and can be used in aerial, duct and direct buried fiber optic cable projects. Fiber splice tray, fiber distribution box and fiber optic enclosure are also offered in conjunction with the splice closures, promoting a safe and well-managed environment for fiber optic splices.
