正常cat5e行100mb有效長度100米,過長要加switch,不過我已經好多年無做,唔知有無新嘢解決到。另外cat6資料以下段嘢喺wikipedia搵番黎,你參考下。
When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is 100 meters (330 ft). This consists of 90 meters (300 ft) of solid "horizontal" cabling between the patch panel and the wall jack, plus 10 meters (33 ft) of stranded patch cable between each jack and the attached device. Since stranded cable has higher attenuation than solid cable, exceeding 10 metres of patch cabling will reduce the permissible length of horizontal cable.
When used for 10GBASE-T, Cat 6 cable's maximum length is 55 meters (180 ft) in a favourable alien crosstalk environment, but only 37 meters (121 ft) in a hostile alien crosstalk environment such as when many cables are bundled together. 10GBASE-T runs of up to 100 meters (330 ft) are permissible using Cat 6a
