What is an ethernet straight through patch cable?
Quote from Joan Francesc on March 26, 2022, 8:40 PMThese ethernet cables are so confusing to me. I have some idea about fiber optic cables, but have almost no idea about ethernet cables. I was trying to figure out the difference between Straight through patch cable and Crossover cables but without much success. Wonder if anyone has simple explanation for straight through patch cable.

There are two types of ethernet cables - Straight through cable, also known simply as patch cable, and the Crossover ethernet cable. Straight through ethernet cable has same color scheme at its both ends. Color scheme is based on T568A or T568B. The color scheme at both ends follow the same color scheme for a Straight Through Cable.
T 568A Color Scheme for wires
Pin 1 - White with Green Stripe
Pin 2 - Green
Pin 3 - White with Orange Stripe
Pin 4 - Blue
Pin 5 - White with Blue Stripe
Pin 6 - Orange
Pin 7 - White with Brown Stripe
Pin 8 - BrownT 568B Color Scheme for wires
Pin 1 - White with Orange Stripe
Pin 2 - Orange
Pin 3 - White with Green Stripe
Pin 4 - Blue
Pin 5 - White with Blue Stripe
Pin 6 - Green
Pin 7 - White with Brown Stripe
Pin 8 - BrownA straight through cable can follow any of the above color scheme, but that color scheme will be same for its both ends. Note the color sequence change between Orange and Green in T 568A and T 568B. Blue and Brown wires stay at their place without change.

Quote from chen on April 20, 2022, 10:50 PMCopper Patch cord cables are available for two different wiring applications. One is for straight-through wiring and the other is for crossover wiring. Straight-through Ethernet cables are the cables that are used to connect between peripherals of different types. Straight through cables are the most commonly used.
If you are connecting a computer and a router, or a computer and a switch, or a computer and a modem, you need a straight through cable. Straight through cable is also used to connect between CAT5 CAT6 peripheral extenders.
There are two color standards that the ethernet cables follow. They are TIA/EIA 568A and TIA/EIA 568B. T568A was implemented in 1995, but the TIA/EIA revised it in 2002 as TIA 568B.
Now, you may wonder what is the difference between TIA 568A and TIA 568B color standards. I will explain it as below;
There are Pins on the connector and these pins are connected with insulated copper wires. The color of the insulation sheath to each pin as per TIA 568A color code is;
Pin 1 - White with Green Stripe
Pin 2 - Green
Pin 3 - White with Orange Stripe
Pin 4 - Blue
Pin 5 - White with Blue Stripe
Pin 6 - Orange
Pin 7 - White with Brown Stripe
Pin 8 - BrownIf TIA 568B color codes are followed, then the sequence of the color is;
Pin 1 - White with Orange Stripe
Pin 2 - Orange
Pin 3 - White with Green Stripe
Pin 4 - Blue
Pin 5 - White with Blue Stripe
Pin 6 - Green
Pin 7 - White with Brown Stripe
Pin 8 - BrownThe wires inside of both connectors of a Straight through ethernet cable follow either T 568A or T 568B. Thus both connector pins of a straight through ethernet cable will have the same color sequence.
