ABSTRACT:
A patch cord into which a collimator pair has been intercalated is attached to the output end of a high-level light amplifier for transmitting high-level light through optical fibers from outside in a replaceable manner. Even if burnout occurs at an end face of an optical fiber and the heat is conducted to the patch cord with collimators that is connected with an optical connector, meltdown by the fiber-fuse phenomenon can be prevented before it reaches the high-power optical amplifier without being propagated to the high-power optical amplifier because heat energy is dissipated at the collimator pair. By this, the high-power optical amplifier can be protected from the fiber-fuse phenomenon.
