摘要： Disclosed herein is an apparatus for generating a parallel beam with a high flux. The apparatus of the present invention includes a light source, a first mirror and a second mirror. The light source is positioned at a first focal point of a first ellipse. The first mirror is positioned on the first ellipse to reflect a beam emitted by the light source, and concavely shaped to conform to a section of the first ellipse. The second mirror is positioned across a path of the beam reflected by the first mirror, and convexly shaped to conform to a section of a second ellipse so that an angle formed by two tangent lines passing through each pair of incident points of neighboring rays incident upon the second mirror, respectively, is half of an angle formed by two tangent lines passing through each pair of incident points of neighboring rays incident upon the first mirror, respectively.

摘要： An optical network terminator of the present invention includes an optical wavelength division multiplexer for receiving an optical signal and incoherent light. An optical detection unit converts a downstream high speed and low speed optical signals into electrical signals. A laser diode converts an upstream signal into an optical signal. A high speed driving unit is supplied with power from a power supply unit to drive a forward-biased laser diode and establish a data and video channel. A high speed reception unit is supplied with the power to receive a downstream data and video channel. A charging unit outputs charged power at the time of a power failure. A low speed driving unit is supplied with the charged power to reverse-bias the laser diode to establish a voice channel. A low speed reception unit is supplied with the charged power to receive a voice channel.
