An arrangement for receiving and/or transmitting RF signals and for feeding the same in a digital format between at least one RF antenna, coil and/or sensor unit (A, B) and a signal processing unit (8), by means of at least one digital cable (121, . . . 12n), especially for use in a magnetic resonance (MR) imaging system is disclosed, wherein at least one of the RF antenna, coil and/or sensor units (A, B) and at least one side of the digital cables (121, . . . 12n) is provided with a digital signal connector (10c, 11a; 121a, 121b, . . . 12na, 12nb) for separably connecting both by plugging the connectors together. By transmitting the RF signals in a digital format, especially in a digital optical format, a plurality of digital cables (121, . . . 12n) with different lengths and digital connectors (121a, 121b, . . . 12na, 12nb) can be used which need not to be an inseparable part of the related RF antenna, coil or sensor, so that a great flexibility is achieved with respect to positioning of the RF antennas, coils and/or sensors for an examination, and a disturbance-free transmission of the RF signals can be ensured as well.
