DEVICE AND METHOD FOR HIGH RATE OPTICAL TRANSMISSION AND USE OF SAID DEVICE AND METHOD

摘要

The invention relates to a device for transmitting a signal across an optical data transmission network, comprising a pulse emitter (10) and at least one fibre line (12) for the transmission of at least one pulse in said fibre line. Said device further comprises a linear pulse expander module (14) with a dispersive and linear propagation means, the cumulative chromatic dispersion of which is sufficiently high to reduce the peak power (Pc) of the pulse below a predetermined threshold. A signal above said threshold is susceptible to non-linear distortions in the fibre line. The expander module (14) is arranged between the emitter (10) and the fibre line (12).
