Title: Frequency division multiplex light transmission system
Inventor: AOYAMA SHIGEYUKI
IPC: H04B10/572
Filed: 1992-11-10
Abstract: PURPOSE:To prevent the deterioration of a C/N corresponding to the fluctuation of the number of channels by varying the amplification factor of a gain variable amplifier in accordance with the value of the number of the channel data. CONSTITUTION:In a first converter 1 at a transmission side, the number of channel data transmitted from a center device 6 are demodulated by a demodulator 14. A gain value corresponding to the data is read from memory 15, and the attenuation of a PIN diode variable attenuator 13 is controlled. That is, the level of a signal outputted by an amplifier 12 is increased in inverse proportion to the decrease of the number of the channels. The signal is inputted to a DFB laser diode 16, and a laser beam is amplitude-modulated. In a second converter 2 at a reception side, the number of channel data are decoded by a demodulator 71. The gain value corresponding to the number of channels is read from a memory 72, and the attenuation of a PIN diode variable attenuator 22 is controlled. As the result, the level of the signal outputted by an amplifier 23 is made equal to a prescribed reference level.

Title: Communication equipment
Inventor: NAGASAKI KAZUNORI
IPC: H04L29/00
Filed: 1992-12-07
Abstract: PURPOSE:To reduce power consumption by setting the low speed operating mode to a comparator so as to stop the oscillation of an oscillator in the communication standby state and releasing the stop state of the oscillator when the comparator detects a change in a communication bus. CONSTITUTION:A sleep signal 101 is set to '1' in the standby state. Thus, a multiplexer MPX303 selects an output voltage of a voltage source 206 and inputs the voltage to a DELAY input of a comparator 300, in which the mode is set to the low speed operating mode not in excess of 1-bit data period. In this case, an output of an OR gate 208 is set to '1' to stop an oscillator 302 supplying an internal clock. When a level of a reception signal RXD changes from '1' to '0' a falling detection circuit 301 outputs a logical '1' and it is inputted to a terminal REL of the oscillator 302 via an OR circuit 204 to release the stop state of the oscillator 302. Thus, the power consumption in the communication standby state is reduced.

Abstract: PURPOSE:To obtain a low-loss, efficient polarizing device by disposing a 1/2- wavelength plate between a polarized light separating plate and a 2nd lens and on the path of only ordinary or abnormal light passing between them, thereby projecting linear polarized light regardless of the polarized state of incident light. CONSTITUTION:Light which is emitted by a single-mode fiber 1 is collimated by a 1st lens 11 into parallel luminous flux, which is made incident on the polarized light separating plate 12 and separated into the ordinary light E0 and abnormal light Ex. Both the light beams have their planes of polarization deviating by 90 deg., but the ordinary light E0 is made incident on a 2nd lens 13 as it is and the abnormal light Ex is made incident on the 2nd lens 13 through the 1/2-wavelength plate 14; and the abnormal light Ex passing through the 1/2-wavelength plate 14 has the plane of polarization rotated by 90 deg., so the plane of polarization is coincident with the plane of polarization of the extraordinary light E0. Consequently, light which is converted after passing through the 2nd lens 13 becomes linear polarized light and the polarization angle of a constant polarization fiber 2 is made coincident with that of the linear polarized light to obtain the polarizing device which has extremely small loss.
