Transmitting device and method for transmitting a broadband optical transmission signal

A transmitting device for transmitting a broadband optical transmission signal via an optical waveguide, having an electronic subsystem and an optical subsystem,

• wherein the optical subsystem has N electro-optic modulators for providing N optical signal components, where N is a number greater than 1,
• wherein the electronic subsystem is configured to transform a baseband signal by a Fourier transform or a discrete Fourier transform, into a frequency spectrum containing N digital coefficient signals, and to provide, on a basis of the N digital coefficient signals, N analog coefficient signals,
• wherein the electro-optic modulators of the optical subsystem are each configured to be driven by one of the N analog coefficient signals, and
• wherein the electronic subsystem comprises N digital-to-analog converters for providing the N analog coefficient signals.
