摘要： The data communication capacity of an existing local area network (LAN) 10 that uses a shielded twisted wire pair 16 as its transmission medium may be increased with the addition of special frequency selective terminators 36 and single-ended transceivers 20. The single-ended transceivers 20 have two single-ended transmitter connections 42,44 to the two twisted wires 22,24 in the shielded twisted wire pair medium 16, respectively, and one single-ended receiver connection 46 to one of the two twisted wires 22,24 in the shielded twisted wire pair medium 16. The shielded twisted wire pair medium 16 is terminated by the special frequency selective terminators 36 which provide transmission line impedance matching over the signal bandwidth of a single-ended data channel, while providing a high impedance over the signal bandwidth of a differential data channel. Thus, differential data communications are allowed over the signal bandwidth of the differential data channel, while single-ended data communications are allowed over the signal bandwidth of the single-ended data channel, thereby increasing the overall data communication capacity of the LAN.
