摘要： A passive optical network includes a central office and a subscriber-side apparatus connected with the central office through an optical fiber link. The subscriber-side apparatus performs communication with the central office based on wavelength-division-multiplexed optical signals. The central office has a routing section, provided with first to fourth multiplexing ports, for demultiplexing multi-wavelength light inputted from the fourth multiplexing port into a plurality of channels. Each of the demultiplexed channels is amplified and multiplexed for output through the first multiplexing port. Optical signals inputted through the third multiplexing port are demultiplexed and outputted upstream. The routing section also multiplexes channels for downstream optical signals, outputting the multiplexed channels through the second port. A splitting section, provided with first to third splitting ports and arranged on a loop optical waveguide connects the first and fourth multiplexing port with each other. The splitting section causes some of multi-wavelength light inputted into the first splitting port to be outputted through the second splitting port and causes the remainder of multi-wavelength light to be outputted through the third splitting port connected with the fourth multiplexing port. A circulator causes the multi-wavelength light inputted through the second splitting port to be transmitted to the subscriber-side apparatus and causes upstream optical signals received from the subscriber-side apparatus to be outputted to the third multiplexing port.

摘要： An optical source generator for wavelength-division-multiplexing optical communication systems includes a wavelength-division multiplexer/demultiplexer, optical amplifiers, and wavelength-dependent reflectors such as optical fiber-Bragg gratings or wavelength-independent reflectors such as mirrors, so as to form laser resonant cavities. Lasing of the optical fibers therefore generates spontaneously emitted lights. Further, the optical source generator controls each reflectance of the respective wavelength-dependent or independent reflectors so that lights amplified within the laser resonant cavities can be used as multi-wavelength optical sources or independent optical sources.

摘要： A duobinary optical transmission device provides duobinary optical transmission with improved quality by a technique that does not require an electrical low pass filter LPF.A duobinary optical transmission device includes at least one semiconductor optical amplifier (SOA). A light source outputs a carrier wave as an optical signal. A precoder encodes an input of a non-return-to-zero (NRZ) electrical signal. An interferometer type semiconductor optical amplification unit modulates the carrier wave according to a change of an applied bias current coupled to the encoded signal. An optical band pass filter (OBPF) receives the phase-modulated optical signal from the semiconductor optical amplification unit, filters the received phase-modulated optical signal according to a designated band, and outputs an optical duobinary signal.
