AUTOMATIC WAVELENGTH CONFIGURATION

摘要

An optical transmitter may include a tunable signal source configured to emit a signal to an optical fiber system; a back scatter detector for measuring an amount of back scatter observed following injection of the signal to the optical fiber system; and control logic. The control logic may be configured to cause the tunable signal source to scan through a range of wavelengths. Measured amounts of back scatter are received for each of the wavelengths. A wavelength corresponding to a peak back scatter amount may be identified and the tunable signal source may be set based on the identified wavelength.
