First used in supercomputers, it has also become a frequent connection format for storage area networks (SAN) within enterprise storage....(more)

Common Types of Fiber-optic Networking and Communication

Fiber-optic networking is useful if you want a high-capacity network or have long runs, like between buildings. There are four types of fiber-optic network topology used to provide communication between a piece of data circuit-terminating equipment (a modem or switch) and a piece of data terminal equipment (a router or work station). Knowing how your fiber network is going to be used helps in deciding the best configuration to employ. Here is some information about the most common types of fiber-optic networking utilized....(more)

The Evolution of Fiber Optic Networking

The fiber optic network began with inventor Alexander Graham Bell in 1880. Bell transmitted sound waves over a light beam with a device he called a photophone. The photophone transmitted sound through light waves in the atmosphere using mirrors for transmissions. Although the photophone was unreliable due to atmospheric conditions, it provided the first step toward the evolution of the modern fiber optic network....(more)
