What is fiber optics splicing ? Fiber Optics splicing is the process of jointing or holding two fibers together There are two methods of fiber optics splicing namely :- a. Fiber Optics Mechanical Splicing  b. Fiber Optics Fusion Splicing  What Is Fiber Optics Mechanical Splicing? In a mechanical splicing, two cleaved fiber tips are mechanically aligned to each other by using a precise housing alignment. An index matching gel is preinstalled between both end cleaved fiber tips to minimize back reflection and to maintain a low-loss optical interface. It is similar function to the fusion splicing except that the fibers are held together by mechanical means rather than by permanent fusion or welding technique. The mechanical splice performance depends on a. cleaving performance b. mechanical splice housing alignment design c. end-user skills and patience The Fiber Optics Mechanical Splicing Concept Basically the mechanical splice process involves five steps:- a. fiber optics stripping b. fiber optics cleaning to remove excess of plastic buffer c. cleaving the fiber optics ends d. inserting the fibers into the mechanical splice housing. This mechanical splice housing retains the fibers so their ends are in contact. Advantages of Mechanical Fiber Optics Splices

The basic optical property of a material is the index of refraction. It is also one of the key parameter that needs to be key-in into OTDR as to get accurate result on actual fiber optics distance measurement. The index of refraction (n) measures the speed of light in an optical medium.  The speed of light (c) in free space or vacumm is  Therefore index of refraction of a material is equivalent to :-  When light enters a different material ( from glass into air or from air into glass)is the speed changes. This causes the light to bend or refract. Light will always travel slower in the fiber material than in air.  The index of refraction for glass is approximately 1.50 or lower.
The index of refraction for air is exactly 1.00. In order to get the actual fiber optics length measurement using OTDR, one is required to enter fiber optics index of refraction into one of OTDR key parameters. The fiber optics index of refraction could be obtained from the fiber optics cable manufacturer. |
AuthorI have been in the field of fiber optics since early 1990s. I gained fiber optics skills and knowledge via my working experience as end-user, main contractor and sub-contractor and finally as an optical fiber enterpreneur. Archives
