摘要： In this paper, with the goal to discover an optimal approach of designing a prospective analog fiber-optic interconnect line, the comparative computer simulation of the quality of transmission parameter is carried out using well-known commercial software VPI Photonics Design Suite. For this purpose, a series of model experiments was realized to measure the laser's relative intensity noise and the output signal-to-noise ratio for cases where direct or external modulation by a radio frequency signal in the band 0.1-20 GHz is used in the transceiving optoelectronic module. In the result, it is clearly demonstrated that, both from a technical and economic point of view the best option for designing a transmitting optoelectronic unit of optical interconnect line is external modulation using off-the-shelf electroabsorption modulated laser.
