Abstract: An RJ 45 connector for unshielded CAT5 cable has electromagnetic-interference-suppression circuitry to meet the Class B conducted and radiated emissions standard. The connector comprises, in addition to signal-conditioning transformers, a current-blocking ferrite and a plurality of pairs of common-mode filters, one pair for each conductor of each active twisted pair of the cable. Each pair of filters is connected in series with each other between a conductor of an active twisted pair and a transformer winding, and meets or exceeds the impedance, reactance, and resistance curves of FIGS. 2-4. The ferrite is connected in series with each conductor of each inactive pair of the cable and across a capacitor to ground, and meets or exceeds the impedance, reactance, and resistance curves of FIGS. 5-7.

Abstract: An electronic module of an electric connector suitable for being electrically connected to a terminal set inside the electric connector is provided. A plurality of connection terminals is installed on the terminal set for electrically connecting other devices. The electronic module includes: a holder having an accommodating space, wherein a plurality of terminal channels is disposed around and communicated with the accommodating space; at least one electronic component, disposed in the accommodating space of the holder, and having at least one conductive lead extending outside the accommodating space; and a plurality of auxiliary terminals with each having a connection end and an insertion end disposed in the terminal channels, wherein the insertion ends correspondingly inserted into the terminal channels lead the conductive leads into the terminal channels, so as to electrically connect the conductive leads. In addition, the connection ends are electrically connected to the connection terminals.

Abstract: Disclosed are an optical module interfacing device for connecting an RJ interface and an SFP type optical module to an SFP type optical module connector without additional processing, and an Ethernet system using the optical module interfacing device, thus supporting data transmission and reception. The optical module interfacing device includes 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 to be 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. Further, UTP data is provided to MDI supporting ports of a physical layer through an interfacing unit.

Abstract: A modular connector for electrically connecting a modular plug to a mother board includes an insulative housing having a vertical front mating face and an electrical module mounted in the housing. The electrical module includes a front PCB parallel the mating face, two mutual parallel second electric circuit boards perpendicularly connecting to the front PCB, and a number of magnetic coils directly mounted on the rear PCBs.
