摘　　要：目的:研制一种端口扩展器配合简易网线测试仪,提高对计算机网络双绞线的测试效率。方法:采用多个RJ-45插座,将其8个接点按相同排列顺序分别并接。任一插座通过短双绞线与网线测试仪的测试端口相连接,其他插座作为扩展端口。结果:经实际测试,仅需一人操作,不需频繁往返于被测线路两端就可方便的对计算机网络双绞线布线进行测试。结论:通过测试证明,该端口扩展器配合简易网线测试仪能明显提高对计算机网络系统双绞线布线的测试工作效率。Objective To develop a port expander for simple network cable tester, which can raise the testing efficiency of the computer network twisted-pair. Methods Several RJ-45 sockets were used to connect the eight points separatedly according to the same arrangement order. One socket was connected to testing port by short twisted-pair, while other sockets were used as expander port. Results In practical test, the operation only needs one person, who could test the computer network twisteded-pair conveniently without going back and forth frequently between the two terminals of the tested line. Conclusion It is proved by testing that the port expander for the simple network cable tester can raise the testing efficiency of the computer network twiist-pair.
