Highly sensitive optical fiber receiving amplifier
Source: InternetPublisher:武林萌主 Keywords: Optical fiber amplifier OPA Updated: 2021/12/29
The high-sensitivity ((InW) optical fiber receiving amplifier is shown in the figure. The OPA 111 feedback resistor reaches 200Mn, so
the gain of the amplifier is very high. The OPA I11 receives the signal transmitted by the optical fiber (9600 baud Manchester data)
. After amplification, it is sent to the voltage comparator LM211 and shaped into a standard data signal .
