THE
DIFFERENT TYPE OF NETWORK GIGABIT CROSSOVER CABLE NETWORKING WITH RJ-45 JACK
ITs use two type of Straight-Through Cable and Crossover Cable:
although the Gigabit crossover is defined in the
Gigabit Ethernet standard, in practice all Gigabit PYHs feature an auto-MDIX
capability and are designed for compatibility existing 100BASE-TX crossover.
The IEEE-specified Gigabit crossover is generally seen as unnecessary.
Certain equipment or installations, including those
in which phone and or power are mixed data in the same cable, may require that
the non-data pair 1 and (pins 4, 5, 7 and 8) remain un-crossed.
The maximum allowable length for a network segment
using 100Base-FX is 412 meters. The maximum length for the entire network is 5
kilometers.

The router takes all the bits being sent out by the
computers and relays them onto the other devices on the network. However, a
crossover cable can be used to connect two devices directly, without the need
for a router in the middle. It simply reverses some of the pins so that the
output on one computer is being sent to the input of another. In the years
before my family had Internet, I used this to play 2-player network games!
This is one use for a cross-over cable; the other is to
expand a network by connecting another network switch, thereby giving you more
ports. It’s always handy to have a length of cross-over cable around!
