A super radio frequency (RF) input device of a superspeed (2.5 Gbps or 10 Gbps) optical communications module, which controls the performance of the module, is provided. In the super RF input device of a super RF optical communications module, microstrip line patterns are formed in a certain size to have inductance and capacitance on a cross-shaped microstrip line, and an electroabsorption modulated laser and a thin film resistor or chip resistor are connected to each other by a bonding wire. Inductance generated here is appropriately controlled by using the length of the bonding wire, so that a 3 dB bandwidth is 13 GHz in a 10 Gbps module, and that an RF return loss increases from 4 dB in the existing module to 14 dB at 10 GHz.
