When did submarines start to be used for communication?
In September 1956, the era of submarine coaxial telephone communication began when two coaxial cables capable of carrying multiple voice channels came into service linking London and North America. Finally, in 1988, the first transoceanic fiber-optic cable was installed linking the U.S., the U.K, and France. Thereafter, the number of submarine fiber-option cables proliferated as they rapidly outperformed satellites in terms of the volume, speed, and economics of data and voice communication. Submarine cables are also an important means of power transmission—particularly in light of the ongoing development of offshore alternative energy generation facilities, such as wind farms.

Overview
Equivalence to other units of area
As a unit of area, the circular mil can be converted to other units such as square inches or square millimetres.
1 circular mil is approximately equal to:
• 0.7854 square mils (1 square mil is about 1.273 circular mils)
• 7.854 × 10 square inches (1 square inch is about 1.273 million circular mils)
Example calculations
A 0000 AWG solid wire is defined to have a diameter of exactly 0.46 inches (11.68 mm). The cross-sectional area of this wire is:
Note: 1 inch = 1000 mils
(This is the same result as the AWG circular mil formula shown below for n = −3)
When large diameter wire sizes are specified in kcmil, such as the widely used 250 kcmil and 35…
Metric equivalent
Some tables give conversions to circular millimetres (cmm). The area in cmm is defined as the square of the wire diameter in mm. However, this unit is rarely used in practice. One of the few examples is in a patent for a bariatric weight loss device.
Standard sizes
Standard sizes are from 250 to 400 in increments of 50 kcmil, 400 to 1000 in increments of 100 kcmil, and from 1000 to 2000 in increments of 250 kcmil.
The diameter in the table below is that of a solid rod with the given conductor area in circular mils. Stranded wire is around 5% larger in diameter to allow for gaps between the strands, depending on the number and size of strands.
