Claims

[Scope of utility model registration request]

In an optical connector for connecting a pair of polarization-maintaining optical fibers with their main axes aligned with each other, the connection should be made using a pipe whose tip surface is processed diagonally with respect to the main axis of the polarization-maintaining optical fiber. The main axes of the polarization-maintaining optical fibers are made to coincide by housing and fixing the tips of each of the polarization-maintaining optical fibers and bringing the pipes into contact with each other using an adapter that can be joined in a turnbuckle manner. An optical connector for polarization-maintaining optical fiber, characterized by:
