Patent ID: 7300214

Claim:
An optical module interfacing device, connected to a female connector for an SFP type module for providing data transmission/reception functions through an UTP cable, comprising: a board having the same dimensions as those of the optical module; a male connector, having the same dimensions as those of the optical module, formed at a side surface of one end of the board and connected to the female connector for the optical module mounted on a host board; and an RJ female connector provided with a plurality of pins formed on an upper surface of the board, respectively corresponding to pins of the male connector, according to standards, wherein the board and the male connector have the same dimensions as those of the SFP type optical module, and optical module pins MOD-DEF 0 , MOD-DEF 1 , MOD-DEF 2 , TX fault, Rate Select and three ground pins out of pins of the male connector are connected to pins of the RJ female connector, further comprising an interfacing circuit for converting power of the male connector into power of the RJ female connector through a regulator and for supplying the power converted by the regulator to connection lines between the optical module pins MOD-DEF 0 , MOD-DEF 1 , MOD-DEF 2 , TX fault, Rate Select and three ground pins of the male connector, and the pins of the RJ female connector, through resistors of designated impedance.
