How do you read a cable code?
An electrical cable is classified by two numbers separated by a hyphen, such as 14-2. The first number denotes the conductor’s gauge; the second denotes the number of conductors inside the cable. For instance, 14-2 has two 14-gauge conductors: a hot and a neutral.

What is Cat 5 Cat6 Cat7 cable?
Cat5e – Has a speed up to 1.000 Mbit/s, 100MHz. Cat6 – Has a speed up to 1.000 Mbit/s, 250MHz. Cat6a – Has a speed up to 10.000 Mbit/s, 500MHz. Cat7 – Has a speed up to 10.000 Mbit/s, 1.000MHz.
What’s the difference between CAT 5 and CAT 8?
For basic Cat5 cables, that’s 100 million signals a second (or 100 Mhz). Cat8 uses an unprecedented 2 billion (2 GHz) signals per second. This means the cable density and quality of shielding necessary to make it work are on a whole different scale.
What does FT6 mean?
FT6 and FT4 refers to the fumes from the outer jacket when the cable is burned. Performance of the cable does not change with the fire rating. Which means this is strictly a fire issue and does not have any bearing on performance of the 2 cables. The bulk cable is usually the smallest cost of a network install.
