Abstract
A method of measuring the bandwidth of a multi-mode optical fiber using single-ended, on-line and off-line approaches and test configurations. The method includes: transmitting a light signal through the first end of a multi-mode fiber toward the second end of the multi-mode fiber, so that a portion of the light signal is reflected by the second end toward the first end of the multi-mode fiber; and receiving the reflected portion of the light signal at the first end of the multi-mode fiber. The method also includes obtaining magnitude and frequency data related to the reflected portion of the light signal at the first end of the multi-mode fiber; and analyzing the magnitude and the frequency data to determine a bandwidth of the multi-mode optical fiber. The length of the multi-mode fiber may also increase over time during testing.
