摘要：

For a binary fiber-optic communication system in which an optical preamplifier is used, and for which the amplifier bandwidth (B) is large compared to the bit rate (1/T), it is shown that the minimum number of photons per bit required to achieve an error probability Pe = 10-9 is given by 36 + 6√BT. This generalizes a result of P.S. Henry (1989) who showed that if the amplifier bandwidth is matched to the signal bandwidth, the sensitivity is 38 photons/bit.
