Abstract:
The invention is directed to a system and method for troubleshooting in an optical data network that has a laser transmitter/receiver unit that outputs a data signal and an OTDR unit that produces an OTDR probe signal. The data and OTDR probe signals, typically at different wavelengths, are coupled into one end of a trunk fiber which is coupled at its far end to an optical circuit that includes a number of wavelength-selective optical switches and has multiple outputs that are directed to different end users. The optical switches are configurable so as to provide the OTDR probe signal to only one of the optical circuit's outputs while maintaining the data signal at the same output, while also maintaining the data signal, without the OTDR probe signal, at other outputs.

Claim (Index 30):
An optical data transmission system, comprising:\n a laser transmitter/receiver unit capable of generating a data transmission signal at a first wavelength; an OTDR unit capable of generating an OTDR probe signal at a second wavelength different from the first wavelength; a first coupler unit coupled to receive the data transmission signal and the OTDR probe signal and to output a combined transmission signal comprising the data transmission signal and the OTDR probe signal; a trunk fiber coupled to receive the combined transmission signal in a first end of the trunk fiber; an optical circuit comprising\n i) an input waveguide coupled to receive the combined transmission signal from a second end of the trunk fiber, \n ii) a plurality of outputs, and \n iii) an optical network comprising a waveguide splitter module connecting between the input waveguide and the plurality of outputs, the optical network having a plurality of output waveguides coupling to respective outputs of the plurality of output, the optical network further comprising at least two wavelength-dependent optical switches disposed on paths taken by the data transmission signal; \n wherein the optical circuit is configurable so as to provide the OTDR probe signal to only one of the outputs while providing the data transmission signal to others of the outputs and to the one of the outputs.
