WAVELENGTH DIVISION MULTIPLEXOR FOR MULTI AND SINGLE MODE OPTICAL CARRIER

摘要

A method and apparatus for automatically providing for both multiplexing and independent external modulation of two or more wavelengths emitted by one or more multi-longitudinal mode laser(s) (26) or other light source. The present invention uses an integrated optics device chip to enable coupling of the dispersed (27) wavelengths into separate electro-optic modulators (131) which encode each of the carrier wavelengths with a different signal. Accordingly, the volume of data which can be transmitted over an optical fiber network is increased. The carrier wavelengths can be transmitted over single or multi-mode optical fibers.
