Abstract
A long transmission link for two-level information which is interrupted at spaced intervals in order that the signal's level-crossing information may be extracted and passed on. This level-crossing remodulation process discards amplitude information and retains and retransmits only the times of level crossing. By making the receiver of each remodulator sufficiently wide-banded, the overall link is protocol and bit rate independent in the sense that it can pass any of a wide variety of binary digital signals without requiring reclocking at each stage as is done with conventional regenerators. The preferred embodiment includes an application to multi-wavelength long optical transmission links, and this multi-channel approach avoids many problems associated with optical amplifiers.
