Abstract
A receiver for digital optical signals, in particular in the soliton format, includes an automatic gain control amplifier and photodetectors for converting the optical signals into electrical signals in a data channel and a clock channel. For detecting signals transmitted optically at high bit rates, the automatic gain control amplifier is an optical amplifier and is on the input side of the photodetectors. There are preferably two photodetectors, the first of which is connected to a data processing channel and the second of which is connected to a clock signal recovery channel. This receiver can receive signals at bit rates exceeding 10 Gbit/s.
