Abstract

Now, single-mode optical fiber has been widely applied in communication systems and the users of optical fiber have migrated to longer transmission wavelengths, which results in the task of optical fiber measurement becoming more difficult. A method measuring optical fiber properties such as fiber loss and attenuation is optical time domain reflectometer (OTDR) measurement. Conventional OTDRs have a limitation: the trade-off between signal-to-noise ratio and response resolution. This paper presents an approach that applies spectrum-spread techniques to remedy this limitation, and improves dynamic range and reduces measurement time without sacrificing response resolution.
