PURPOSE:To install optical fibers in close contact with the corner part or the angular part of an OTDR when they are mounted in the inside of the OTDR by preventing the taking-out of the optical fibers from being faced. CONSTITUTION:Two total reflection mirrors 12 being a second light transmission means are provided in opposite to the single-mode optical fiber for input 5 and the single-mode optical fiber for output 4. Thus, the optical fibers 4-6 can be arranged on one surface of a housing 11. |
