What do the red yellow and white cables mean?
What do the red yellow and white cables mean?
They are often color-coded, yellow for composite video, red for the right audio channel, and white or black for the left channel of stereo audio. Varying cable quality means that a cheap line-level audio cable might not successfully transfer component video.
How do I color code my Ethernet cable?
A good way of remembering how to wire a Crossover Ethernet cable is to wire one end using the T-568A standard and the other end using the T-568B standard. Another way of remembering the color coding is to simply switch the Green set of wires in place with the Orange set of wires.
Does Ethernet use all 8 wires?
Usually a typical ethernet network cable is made-up of 4 pairs, or 8 wires in total. Normally 10Mbps or 100Mbps ethernet only uses 4 of those 8 wires, or 2 pairs. But some older network cards needed all 4 pairs for full-duplex connections, as in 100TX4.
What is cable color code?
Color coding The color combinations are applied to the insulation that covers each conductor. The major, or primary group of colors consists of the sequence of white, red, black, yellow, and violet. The minor, or secondary color was chosen from the sequence blue, orange, green, brown, and slate.
Are all wires used in Cat5?
If you make the proper math, with a 100 Mbps data transfer rate, the clock rate of 100BaseT is of 125 MHz (10/8 x 100). So, Cat 5 cables are certified to have a transmission speed of up to 125 MHz. Also, instead of using just four wires of the cable, Gigabit Ethernet uses all wires.
Which Ethernet wires are actually used?
The RJ45 data cables we use to connect computers to a Ethernet switch is straight-through cables. As noted above, the RJ45 cable uses only 2-pairs of wires: Orange (pins 1 & 2) and Green (pins 3 & 6). Pins 4, 5 (Blue) and 7, 8 (Brown) are NOT used.
How many cables does CAT 6 have?
A Cat6 cable is similar to a Cat5 ethernet cable — it consists of four pairs of twisted copper wire. However, it provides you with much more functionality. A Cat6 cable has a bandwidth capacity of 250 MHz, for example, and it offers you speeds of up to 10 Gbps.
