This article describes the working principle of mechanical splices and different designs. You can get the fiber mechanical splice products here or by clicking on the following picture.   What Is Mechanical Fiber Splice? Fiber optic mechanical splice performs a similar function to the fusion splice except that the fibers are held together by mechanical means rather than by a welding technique. Mechanical splices somewhat look like fusion splice protection sleeves. In a mechanical splice, two cleaved fiber tips are mechanically aligned to each other by a special housing. Usually, index matching gel is positioned between the fiber tips to

Corning CamSplice single mode mechanical splice features a patented “cam” fiber locking mechanism and requires no adhesive. The “cam” fiber alignment method self-centers the fibers and provides high precision alignment. The average loss for the CamSplice mechanical splice is about 0.15dB with a maximum loss at 0.3dB. One single part works for 250um/250um, 250um/900um and 900um/900um mechanical splice applications. Assembly process for the CamSplice single mode mechanical splice Strip the fibers Cleave the fibers Insert the fibers in the splice until they touch Turn the cams to lock the fibers The CamSplice single mode mechanical splice requires no adhesive and special tools. (But an

The 3M Fibrlok 2540G fiber splice tool is designed to enable fast, easy splicing of 250-micron singlemode fiber in FTTP installations and in multimode enterprise installations. The Fibrlok 250um fiber splice is designed to be installed at the drop in fiber distribution terminals and optical network terminals outside and at fiber distribution units and wall outlets indoors. According to the company, the low-loss splice provided by the tool can be installed with little or no training by nonspecialized technicians working inside buildings or outdoors. With the tool, several crews can be equipped for less than the cost of a single

Fusion splice process is to literally weld two prepared fiber ends together, thereby creating a permanent joint with the minimum possible insertion loss. The fusion splice process is illustrated as follows. So what factors in the fusion splice process determine the insertion loss achieved? The loss mechanism in fusion splice joint may be summarized as follows: Core misalignment. Although normally aligned using the cladding diameter as the reference surface, it is generally believed that the complex surface tension and viscosity structures within the core and the cladding do tend to minimize the actual core misalignment. Core diameter. The allowable diameter
