1000Base-T SFP
Zheng Peng, HE Guiming, Zhu Liwu · 2004
Gigabit Ethernet is rapidly becoming the network of choice from the backbone to the access. The IEEE 802.3ab Gigabit Ethernet standard represents extraordinary technology in that it defines 1000Mb/s data transmission over Category 5 UTP cable. Also because of the demand what requires port density of system, so the 1000Base-T SFP is needed. The paper discusses the design of 1000Base-T SFP from the aspects of circuitry design, PCB design and EMC design. The 1000Base-T SFP that we have fabricated has 10/100/1000M auto-negotiation capability with high quality of performance.
