COMMUNICATIONS LINK OPTICAL AMPLIFICATION AND DISPERSION COMPENSATION

摘要

Fiber optic communication links are disclosed, employing non-invasive fiber optic amplification technology. An amplifier stage (1024) is provided having a plurality of signal paths into which differing wavelength windows of an input optical signal are demultiplexed. At least one of the paths (e.g., 1310 nm) includes a fiber optic (30) and an associated fiber optic amplifier (1054). A channel overlay waveguide (60) is employed for amplification of optical energy evanescently coupled to the overlay waveguide from the fiber optic (30).
