Abstract
A technique for compensating undesired effects in optical links of an optical communication network, using adjustment modules suitable for inserting into optical links, preferably into the links incoming network nodes. Each of the adjustment modules serves for compensating two or more different physical effects accumulated in the optical link when transmitting an optical signal there-along. The module comprises at least two controllable blocks respectively comprising a variable gain optical amplifier VGA for selectively compensating power loss and a tunable dispersion compensation module TDCM for selectively compensating chromatic dispersion.
