Claim Text:
1. An optical transmitter used for a time division multiplexing system, the optical transmitter comprising: a Fabry Perot-Laser Diode (FP-LD) driven by an electric signal, the FP-LD configured to, an optical coupler coupled with the FP-LD, and configured to feed the modulated multiple-longitudinal mode light wave from the FP-LD to a fiber Bragg grating, wherein the fiber Bragg grating is configured to, the optical coupler is configured to divide the filtered light wave into a first branch optical signal and a second branch optical signal, the first branch optical signal being fed back to the FP-LD, and the second branch optical signal being fed to a detector, the detector is configured to judge whether a wavelength and a power of the second branch optical signal meet a condition, when the condition is not met, when the condition is met, the second branch optical signal is provided as an output of the optical transmitter.
