In a gigabit network-the difference between using five types of lines, super five-class lines, and class six lines

Last year, I started a Seagate Central. There is no time to study, direct plug on the use. Intranet speed has been maintained around 10m-15m. This year 618 changed the gigabit router, the speed of the instant upgrade to the 50m-70m. Cable used are five categories, the heart of the question: if replaced by Super Five class line or six class line, performance can not be improved point?? So on-line search a friend very professional answer, can't help sticking down to share with you:

Class 5 Transmission Frequency standard is 100MHz Ultra 5 is generally 125MHz 6 class standard specification is 250MHZ Enhanced 6 class standard is 500MHz

However, many well-known manufacturers of product transmission frequency standards are higher than the specified

The standard 1000base-t of the Thousand m line

Based on the 802.3AD standard transmission Media CAT5 4-wire simultaneous bidirectional transmission CAT5e can also be compatible with Class 6 lines

General type 6 line generally refers to the transmission frequency bit around 250mhz twisted pair

The corresponding standard in practical application is 1000BASE-TX but there are not many devices that support this standard.

It differs from the standard 1000base-t of the Thousand M line by "using 4-wire transmission but alone with 2 to receive a separate 2-to-send"

Reduced line usage (use only 2 pairs of lines to receive 2-wire transmission) reduces crosstalk

So the request is more than the Class 5 line has a stronger transmission frequency can only use 6 lines to do transmission media

CAT6A Enhanced Class 6 line standard 10GBASE-T Gigabit Ethernet protocol is 820.3an also use 4-wire bidirectional transmission

The specified transmission frequency is 500MHz or higher.

Shielded line divided into two types of STP and FTP price expensive installation difficulties

Requires a special connector and wire at both ends of the ground and the entire network system is shielded type devices have effect.

So it's generally used only in places where confidentiality is high.

What standard protocols are supported on the port of your device to determine which transmission medium to use, except for YY

Landlord if the standard is directly connected to thousands of M network card 1000BASE-T use 4 pairs of wire at the same time to use any kind of media can most commonly of course is used CAT5e
