Optical Fiber Technology
Optical Fiber is a technology that uses glass (or plastic) threads (fibers) to transmit data. The operation of an optical fibre is based on the principle of total internal reflection. Light reflects or refracts, depending on the angle at which it strikes a surface. A fiber optic system is similar to the copper wire system. The difference is that fiber-optics use light pulses to transmit information down fiber lines instead of using electronic pulses to transmit information down copper lines. Looking at the components in a fiber-optic chain will give a better understanding of how the system
...Easy-to-Use Optical Light Source

The Basics of Passive Optical Networking
A passive optical network (PON) configuration reduces the amount of fiber and networking infrastructure necessary as compared to traditional point to point architectures.
Wave Division Multiplexing (WDM) is used to combine and break-out multiple optical carrier signals on a single optical fiber by using different wavelengths (aka colors) of laser light to carry the different signals. This technology permits for a multiplication in capacity, in addition to enabling bidirectional communications over one strand of fiber.
Downstream signal coming from the service head-end to the
