<P>PROBLEM TO BE SOLVED: To provide an optical fiber measuring apparatus, an optical fiber measuring method, and a multiplexed light generating method that can simultaneously perform OTDR measurement and identification of a coated optical fiber. <P>SOLUTION: In an optical fiber measuring apparatus, an optical fiber measuring method, and a multiplexed light generating method, pulse light generated from a single light source is modulated at a constant cycle to generate a multiplexed light including both components of light for identifying a coated optical fiber and OTDR test light. The multiplexed light can be obtained by modulating the pulse light at the constant cycle by turning on/off an optical switch. <P>COPYRIGHT: (C)2013,JPO&INPIT |
