Abstract: We suggested a new PCI Express Optical Repeater Device which can locate I/O Devices externally for I/O expansion, not locate all I/O Devices in Server that has limit in Volume and Power in this paper. This Device doesn’t convert PCI Express signal to Optical Signal directly, but in PCI Express Switch Architecture, uses the layered architecture to make Switch’s internal bus or interconnection the optical interface. Thus there is no disadvantage of wasting bandwidth. This solves signal attenuation and over-power dissipation for the sake of Optical Interface Characteristics and can meet distances requirement for Server Environment. We expect that the methods and research results in this paper can be used in Small Server which will want I/O Expansion.
