OPTICAL PULSE REGENERATING TRANSMISSION LINES

摘要

In the present invention an optical pulse regenerating transmission line element (10) includes a section of disbursement managed optical fibre transmission line (12) in optical communication with an unbalanced optical interferometer (14). The transmission line element may be particularly suitable for use with RZ optical pulses, and in particular optical solitons. The dispersion managed optical fibre transmission line includes a first section of optical fibre (18) having a negative dispersion coefficient, connected to a second section of optical fibre (16) having a positive dispersion coefficient. This first section of fibre (18) may be dispersion compensating fibre and the second section of fibre (16) may be standard monomode fibre. It is preferred that the first and second sections of optical fibre are arranged to form a section of dispersion managed optical fibre transmission line having a symmetric dispersion map.
