100메가급 단순 허브 사용, RJ45잭은 CAT.5 사용 조건 입니다.
200M 거리에 CAT.6 케이블에 RJ45잭은 CAT.5 사용 했더니 신호가 가질 않네요
흠냐... CAT.5 깔라고 했더니 6이 더 멀리 간다고 6으로 깔아놓고 증폭기나 중간에
허브 달자는데 전신주에 달아야 할판 입니다. 전기도 끌어야 하구요
추가 비용 없이 해결 방법 없을까요?

Maximum length
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. However, because the effects of alien crosstalk environments on cables are difficult to determine prior to installation, it is highly recommended that all Cat6 cables being used for 10GBASE-T are electrically tested once installed. Because it would take much work to test every cable in the field, and because of the risk of having a nonworking installed cable, one should use Cat6A cable in all 10GBASE-T applications. Cat6A does not need to be tested after installation. Cat6A does not have this limitation and can run 10GBASE-T at 100 meters (330 ft).
