Straight through ethernet cable color coding

narrative guide on how to fabricate utp cable

1. A. Straight Through Cable
You usually use straight cable to connect different type of devices. This type of cable will be
used most of the time and can be used to:
1) Connect a computer to a switch/hub's normal port.
2) Connect a computer to a cable/DSL modem's LAN port.
3) Connect a router's WAN port to a cable/DSL modem's LAN port.
4) Connect a router's LAN port to a switch/hub's uplink port. (Normally used for expanding
network)
5) Connect 2 switches/hubs with one of the switch/hub using an uplink port and the other one
using normal port.

B. Crossover Cable
Sometimes you will use crossover cable, it's usually used to connect same type of devices. A crossover
cable can be used to:
1) Connect 2 computers directly.
2) Connect a router's LAN port to a switch/hub's normal port. (normally used for expanding network)
3) Connect 2 switches/hubs by using normal port in both switches/hubs.

2. Ethernet Cable Tips:
 A straight-thru cable has identical ends.
 A crossover cable has different ends.
 A straight-thru is used as a patch cord in Ethernet connections.
 A crossover is used to connect two Ethernet devices without a hub or for connecting two hubs.
 A crossover has one end with the Orange set of wires switched with the Green set.
 Looking at the RJ-45 with the clip facing away from you, Brown is always on the right, and pin 1 is on
the left.
 No more than 1/2" of the Ethernet cable should be untwisted otherwise it will be susceptible to
crosstalk.
 Do not deform, do not bend, do not stretch, do not staple, do not run parallel with power cables, and
do not run Ethernet cables near noise inducing components.
