七類線和六類線的區別

详情描述：

七類線是目前較新的一種雙絞線，主要適應萬兆位以太網技術的應用和發展。
什麼是七類網線?
七類線是一種8芯屏蔽線，每對都有一個屏蔽層，然後8根芯外還有一個屏蔽層，接口與現在的RJ-45相同。七類線高傳輸頻率 
600MHz，超七類線的傳輸頻率為1000MHz。
七類線和六類線的區別
帶寬：六類布線系統提供至少200MHZ的綜合衰減對串擾比及整體250MHZ的帶寬;七類系統則提供至少500MHZ的綜合衰減對串擾比和600MHZ的整體帶寬。
結構：六類布線既可以使用UTP，也可以使用STP;七類網線只基於屏蔽線纜。
因此目前七類線適合信息保密性高，網速穩定的場所。

What is the CAT 7?
the CAT 7 is an 8-core shielded cable with a shield on each pair and a shield 
on the outside of the 8 cores. The interface is the same as the current RJ-45. 
The highest transmission frequency of the CAT 7 line is 600MHz, and the 
transmission frequency of the CAT 7e line is 1000MHz.
The difference between the CAT 7 and the CAT6
Bandwidth: the CAT6 systems provide a combined attenuation-to-crosstalk ratio 
of at least 200 MHz and an overall 250 MHz bandwidth; the CAT 7 systems provide 
a combined attenuation-to-crosstalk ratio of at least 500 MHz and an overall 
bandwidth of 600 MHz.
Structure: the CAT6 can use either UTP or STP; the CAT 7 are based only on 
shielded cables.
Therefore, the CAT 7are suitable for places with high information 
confidentiality and stable network speed.
