Dense wavelength division multiplexing (DWDM) is a technology that puts together -- multiplexes -- data signals from different sources so they can share a single optical fiber pair while maintaining complete separation of the data streams.
Fiber optics, or optical fiber, refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber.
Fiber to the x (FTTx) is a collective term for various optical fiber delivery topologies that are categorized according to where the fiber terminates
A passive optical network (PON) is a system that brings optical fiber cabling and signals all or most of the way to the end user.
An ROADM (reconfigurable optical add-drop multiplexer) is a device that can add, block, pass or redirect modulated infrared (IR) and visible light beams of various wavelengths in a fiber optic network. ... (Continued)
