AbstractA direct modulated optical link for MR coil array interconnect has been developed. The link uses a diode laser to modulate RF signals directly, and needs only one fiber for each channel. It has a power gain of ¨C18dB, noise figure of 29dB and dynamic range of 110dBHz. The noise figure can be reduced to below 1dB by a low noise preamp. Compared with an external modulated optical link, a direct modulated link has simpler link structure, lower cost and more compact size, so it is more advantageous for large coil array interconnect.
