Patent number: 8682164Abstract: An optical wavelength division node includes an optical splitter, a plurality of optical circulators, and a colorless light source module. The optical splitter receives and splits a downstream signal light source into a first-path and a second-path signal light source. The optical circulator in a first-order position receives and transmits the first-path signal light source to an optical network unit in a first-order position, and receives a return signal and passes it to a next optical circulator, and finally the optical circulator in a last-order position receives the return signal and transmits it. The colorless light source module receives the second-path signal light source and the return signal transmitted by the optical circulator in a last-order position, and uses the second-path signal light source to modulate the return signal to generate an upstream signal light source to be transmitted to the optical line terminal by the optical splitter.Type: GrantFiled: March 22, 2012Date of Patent: March 25, 2014Assignee: Industrial Technology Research InstituteInventors: Po-Lung Tien, Maria C.

Publication number: 20130343760Abstract: A system and a method for optical transmission are provided. The system includes a power combiner, a laser light source, a negative chirp modulator, and multiple transmission units. Each transmission unit corresponds to a frequency band and generates a first output signal in the frequency band based on orthogonal frequency-division multiplexing (OFDM). The frequency bands are not overlapped with each other. The power combiner is coupled to each transmission unit. The power combiner combines each of the first output signals to generate a second output signal. The negative chirp modulator is coupled to the power combiner and the laser light source. The negative chirp modulator performs negative chirp modulation on the laser light source with the second output signal to generate a light signal and outputs the light signal to an optical fiber.Type: ApplicationFiled: October 16, 2012Publication date: December 26, 2013Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Hsing-Yu Chen, Chien-Hung Yeh

Patent number: 8391716Abstract: A signal transmission system for a peer-to-peer optical network. The system includes an optical line terminal, an optical distribution node, and a plurality of optical network units. The optical network unit and the optical distribution node are connected in a tree distribution having an ordered relation. The optical line terminal transmits optic signals via the optical distribution node to a first ordered optical network unit, to allow the first ordered optical network unit to process the optic signals and to generate combined optic signals, which are transmitted to a next ordered optical network unit via the optical distribution node. The above steps are iterated, until a last ordered optical network unit transmits combined optic signals to the optical line terminal via the optical distribution node.Type: GrantFiled: January 27, 2011Date of Patent: March 5, 2013Assignee: Industrial Technology Research InstituteInventors: Hsing-Yu Chen, Jye-Hong Chen, Maria C.
