Patent ID: 8315524

Claim:
An electro-optic conversion module, comprising: an electric interface unit; a plurality of electro-optic conversion units coupled to the electric interface unit; a multiplexer unit coupled to the plurality of electro-optic conversion units; and an optical interface unit, wherein the electric interface unit is configured to receive multiple electric signals to be converted, and transmit each electric signal to be converted to a corresponding electro-optic conversion unit, wherein the electro-optic conversion units are configured to convert the electric signals from the electric interface unit into optical signals, wherein the multiplexer unit is configured to multiplex the optical signals from the electro-optic conversion units into a wavelength division multiplexed signal, wherein the optical interface unit is configured to output an optical signal from the multiplexer unit, wherein the electric interface unit comprises an electric socket interface, configured to receive the multiple electric signals, and wherein in the electric socket interface, input pins for the electric signals to be converted are adjacent to each other, so that every two of the electric signals compose a differential signal pair, pins surrounding the input pins for differential signal pairs are grounded signal pins, and the input pins for the differential signal pairs are spaced by at least two pins.
