Method for transmitting data with an optical wavelength multiplex system subdivides a wavelength band into two adjacent sub-bands with a preset band gap at a minimum wavelength distance to avoid crosstalk.

摘要

A wavelength band is subdivided into two adjacent sub-bands (S1,S2) with a preset band gap (a) at a minimum wavelength distance to avoid crosstalk. A monitoring channel (u) controls/monitors data transmission on effective channels (n) and fits in the band gap between the two adjacent sub-bands.
