The easiest way to figure it out would be to stand on the line the 4x100 uses. then just measure the distance back to the starting line. so it would be 400 + x = distance of 1 lap in outside lane. 1  not strong in math. 2  RE: How long is the outside lane of a 400m track? 3  not strong in math. 4  Reply. 5  Return to Index. 6  Report Post.
Horizontal fiber cable cost is calculated using $0.50/fiber/meter for two fibers. Vertical fiber cable cost is 98.4 feet at $0.50/fiber/meter for two fibers. Again, the costs used for the model represent a starting point.
Over the last 20 years or so, fiber optic lines have taken over and transformed the long distance telephone industry. Optical fibers are also a huge part of making the Internet available around the world. When fiber replaces copper for long distance calls and Internet traffic, it dramatically lowers costs. To understand how a fiber optic cable works, imagine an immensely long drinking straw or flexible plastic pipe. For example, imagine a pipe that is several miles long. Now imagine that the inside surface of the pipe has been coated with a perfect mirror.
