摘要： A system includes an Optical Time Domain Reflectometer (OTDR) that injects a first OTDR signal at a first optical wavelength, a first power level and a first polarization state into an optical fiber. The system further includes an OTDR monitor that monitors multi-band optical signals on the optical fiber, selects a second power level and a second polarization state based on the monitoring of the multi-band optical signals, and determines parameters associated with the optical fiber based on the monitoring. The OTDR injects a second OTDR signal at the first optical wavelength, the selected second power level and the selected second polarization state into the optical fiber. The system operates to allow un-balanced power levels across multiple wavelength bands to be balanced due to inter-channel Raman power shift.

摘要： A system includes an optical fiber cross-connect module with upstream ports and downstream ports, a first set of optical fibers connected from optical line terminals to the upstream ports, and a second set of optical fibers connected to the downstream ports and a customer optical network unit. The optical line terminals provide multiple wavelengths carrying optical signals at different bitrates over the first set of optical fibers. The customer optical network unit includes a tunable filter configured to receive any one of the multiple wavelengths. The optical fiber cross-connect module divides the optical signals received at each of the upstream ports into each of the downstream ports, and the customer optical network unit may be tuned to pass through a particular wavelength from the multiple wavelengths.

摘要： A method includes determining a first power level by performing a first series of measurements based on a first series of burst transmissions from an optical transmitter of an optical network unit (ONU) in an optical network. Bursts in the first series of burst transmissions include a first modified preamble. A second power level is determined by performing a second series of measurements based on a second series of optical burst transmissions. Bursts in the second series of burst transmissions include a second modified preamble. A first power level (P0) and a second power level (P1) are determined based on the first power level and the second power level and one or more additional parameters associated with transmissions from the optical transmitter are determined based on P0 and P1. Based on the additional parameters, it is determined whether the optical transmitter complies with specifications of the optical network.
