What is bandwidth distance product?
The term bandwidth–distance product (or bandwidth–length product) is often used in the context of optical fiber communications. It is usually defined as the product of the length of a fiber-optic link and its maximum signal bandwidth.
What is bandwidth in optical fibre?
Bandwidth refers to the amount of data you can transfer in a unit of time, as well as the range of frequencies used to transmit the data. Fiber-optic bandwidth is high both because of the speed with which data can be transmitted and the range of frequencies over which data can travel without attenuation.
