내부적으로 대용량의 트래픽 전송을 위해 10G 네트워크 구축이 일반화 되었습니다.
STP 또는 Optical 로 구축하는데 비용이 현실적인 수준으로 낮어졌고 네트워크 인터페이스 카드 또한 저렴해진 덕분에 영상편집 분야나 대용량 PACS 이미지 전송이 많은 병원등에서 꾸준하게 구축의뢰가 들어오고 있습니다.
대 부분의 공사업체가 CAT6A 또는 Optical 케이블로 기존의 방식과 동일하게 공사를 하게 되면 큰 문제가 발생하지 않지만 당사는 다음 사항을 고려하여 깔끔하고 저렴하며 장애가 없도록 구축해 드립니다.
- 고급 네트워크 라우팅 및 장비에 대한 지식 및 자격증보유
- 벤더 종속적이지 않으며 고객에게 가성비가 가장 우수한 제품의 10G 스위치 제안 가능
- 전문계측장비로 선로 테스트 후 pass값 레포트 제공 가능
체크사항 : Level V Accuracy, Resistance Unbalance, Shield integrity, distance to fault,
TCL, ELTCTL, CDNEXT, CMRL
- 저렴한 Optical 10G네트워크(In Door) 구축 가능
- 저렴한 2.5G 기업용 인터넷 제공 가능

Category 6A
The standard for Category 6A is ANSI/TIA-568-C.1, defined by the Telecommunications Industry Association (TIA) for enhanced performance standards for twisted pair cable systems. It was defined in 2009. Cat 6A performance is defined for frequencies up to 500 MHz—twice that of Cat 6. Cat 6A also has an alien crosstalk specification as compared to Cat 6, which picks up high levels of alien noise at high frequencies.
The global cabling standard ISO/IEC 11801 has been extended by the addition of amendment 2. This amendment defines new specifications for Cat 6A components and Class EA permanent links. These new global Cat 6A/Class EA specifications require a new generation of connecting hardware offering far superior performance compared to the existing products that are based on the American TIA standard. The most important point is a performance difference between ISO/IEC and EIA/TIA component specifications for the NEXT transmission parameter. At a frequency of 500 MHz, an ISO/IEC Cat 6A connector performs 3 dB better than a Cat 6A connector that conforms with the EIA/TIA specification. 3 dB equals 50% reduction of near-end crosstalk noise signal power; see half-power point.
Confusion therefore arises because of the naming conventions and performance benchmarks laid down by the International ISO/IEC and American TIA/EIA standards, which in turn are different from the regional European standard, EN 50173-1. In broad terms, the ISO standard for Cat 6A is the most stringent, followed by the European standard, and then the American (1 on 1 matching capability).
Maximum length
When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is up to 100 meters (328 ft). This consists of 90 meters (295 ft) of solid "horizontal" cabling between the patch panel and the wall jack, plus 5 meters (16 ft) of stranded patch cable between each jack and the attached device. For 10GBASE-T, an unshielded Cat 6 cable should not exceed 55 meters and a Cat 6A cable should not exceed 100 meters.
