对投身于兆位以太网的厂商来说,尽管有很多选择,但迟迟不出台的IEEE 802.3ab标准可能仍是在双绞线上传输千兆速率的最佳解决方案。 IEEE最近的一次年会将双绞线作为千兆位以太网的标准用线,因为大多数网络管理员部不希望废弃已经布设的长距离五类双绞线而去重新铺设昂贵的光纤网络,这样做的代价实在太高了。对802.3ab有重大推进动力的是千兆位以太网协会,会员有Alteon公司、3Com公司、
Despite the many options for vendors dedicated to megabit Ethernet, the not-yet-introduced IEEE 802.3ab standard may still be the best solution for transmitting gigabit rates over twisted pair. The recent IEEE annual conference put twisted-pair as the standard line for Gigabit Ethernet because most network managers do not want to abandon long-haul Category-5 twisted-pair cables already deployed and re-route expensive fiber-optic networks, The cost of doing so is too high. A significant advance for 802.3ab is the Gigabit Ethernet Association, which includes Alteon, 3Com,
