OPTICAL THRESHOLD RECEIVER FOR A VARIABLE-SPEED DIGITAL TRANSMISSION SYSTEM |
摘要 |
An optical receiver designed for operation in alternating-current transmission over a broad temperature range and having a very large dynamic range comprises a capacitor between the transimpedance circuit and two comparator circuits for processing a signal which is coded at three levels. The amplifier can be of a type having a wide band but excluding the direct-current component. A threshold-generating circuit permits automatic connection of the thresholds to one of a plurality of discrete values which are predetermined as a function of the variation in amplitude of the signal. The optical link transmitter delivers the coded information in accordance with a code having a constant direct-current component such as a PBP code, for example. |
