Title: Carrier detector
Inventor: WATANABE HIDEKO
IPC: H04B7/26
Filed: 1989-05-31
Abstract: PURPOSE:To detect the presence of a carrier accurately regardless of a temperature change by boosting the reference voltage of a comparator when the comparator detects the carrier in the case of receiving no external signal. CONSTITUTION:A signal from a mixer 14 is amplified and detected by an interface IC circuit 15, and the signal is amplified by an amplifier 16 and the amplified carrier voltage and a reference voltage from a reference voltage setting device 18 are compared by a comparator 17 to output a detection signal representing the presence of the carrier. The reference voltage setting device 18 is controlled by a microcomputer 10. When no external signal is received and the comparator 17 detects the carrier, the reference voltage of the comparator 17 is boosted. Thus, the change in the amplification factor is detected by detecting the carrier component of internal noise. Consequently, when the reference voltage of the comparator 17 is controlled in response to the amplification factor, the presence of the carrier is detected accurately regardless of temperature change.

Abstract: PURPOSE:To obtain an optical fiber preform capable of reducing transition loss without dehydrating for a long time, by specifically treating a cylindrical soot preform having piled glass fine particles and making the treated preform into transparent glass. CONSTITUTION:Glass fine particles are piled to form a cylindrical soot preform and the soot preform is dehydrated.
