A technique which employs more than one light source and detector operating at different wavelengths and simultaneously transmits optical signals through the same fiber while message integrity of each signal is preserved.
Key enabling technology that increases bandwidth capacity by combining beams of light of slightly different wavelengths through a single fiber, with each fiber carrying its own stream of information.
a technology that increases the number of wavelengths on a single beam of light. Using DWDM, more than 75 separate wavelengths can be multiplexed into a lightwave transmitted on a single optical fiber.
