Infrastructure for transporting radio-frequency data via optical fibers

A radio-frequency data transport infrastructure configured to transmit radio-frequency data to an equipment, in a direction of a downstream flow, and to transmit the radio-frequency data from the equipment, in a direction of an upstream flow, comprising:

• N optical fibers;
• S interface boxes;
• a concentration and configuration box comprising:
• a first filter frequency filters in the direction of the downstream flow and decomposes an entering signal into N entering sub-signals in N distinct sub-bands of frequencies, N being an integer ≥2;
• N signal converters, each signal converter, in the direction of the downstream flow, respectively converts an entering sub-signal into an entering optical signal having a first wavelength;
• wherein the concentration and configuration box is coupled, via the N optical fibers to the S interface boxes disposed in series, S being an integer ≥2;
• wherein each interface box comprises:
• N 1×2 optical couplers;
• N optical signal converters, each optical coupler, in the direction of the downstream flow, respectively transmits a part of the entering optical signal to an optical signal converter, each optical signal converter, in the direction of the downstream flow, respectively reconverts the entering optical signal into the entering sub-signal;
• and
• a first signal multiplexer recomposes the entering signal from the N entering sub-signals obtained by the N optical signal converters.
