Title: Splicing method for different kind of optical fiber
Inventor: SUZUKI TETSUO
IPC: G02B6/255
Filed: 2001-06-12
Abstract: PROBLEM TO BE SOLVED: To connect different kinds of optical fibers having a different mode field diameter (MFD) with low connection loss and with high strength. SOLUTION: An optical fiber is so structured as the outer circumference is covered with a coating layer. After the coating layer is removed at the connecting end of the optical fiber, the connecting end faces of the different kinds of optical fibers are abutted on each other for fusion splicing (step S4). Subsequently, the connecting part of the optical fibers are cleaned. Then, the connecting part of the optical fibers are heated, with the MFDs matched for the optical fibers to be spliced. As a result, connection loss can be controlled to be low. After that, a protective layer is formed from the outer peripheral face of the exposed root of the optical fiber over to the upper face at the end of the coating layer. Then, the connecting part of the different kinds of optical fibers is etching-treated.  Since the etching gas is prevented from entering a gap between the coating layer and the optical fiber, useless etching is avoided, suppressing deterioration of the strength.
