Crosstalk analysis of 4X48 parallel optical interconnect system based on VCSEL/CMOS optoelectronic chip and 2-D optical fiber data link

摘要

In this paper, the crosstalk influence between signal channels of 4 x 48 free-space parallel optical interconnect network system basedo n VCSEL/CMOS optoelectronic chip and 2-D optical fiber data link is studied. The crosstalk anaalysis shows that the crosstalk between signal channels may be reduced by introducing a small displacmenet at vertical direction. This optical interconnection system can realize 12-bit wide bi-directional data transfer between four computers through a 4 x 48 high density 2-D optical fiber data link. The finfluence of the crosstalk would be reduced in this optical interconnect system.
