Title: Optical receiver and method for adjusting band width of the optical receiver
Inventor: WIAND PATRICK
IPC: H04B10/43
Filed: 2000-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a relatively easy and direct constitution for improving the control of the band width of an optical receiver. SOLUTION: A voltage adjuster 20 is used for adding an input supply voltage to a preamplifier 14 of this optical receiver. The preamplifier 14 indicates the band width which is the function of an input voltage and the voltage adjuster 20 can be adjusted by an incorporated potentiometer. At operation, the band width of the optical receiver is measured first. In the case that the band width is too small, the potentiometer is adjusted so as to increase the input voltage added to the preamplifier 14 by changing resistance detected by the voltage adjuster 20. By the change in the input voltage, the band width of the preamplifier 14 is increased, and the 3dB cutoff frequency of the optical receiver rises.  Conversely, in the case that the measured band width of the receiver is too large, the potentiometer is adjusted so as to reduce the voltage added to the preamplifier 14 by the voltage adjuster 20.
