Abstract

See full text

A system for connecting two or more dense wavelength division multiplex (DWDM) systems in an optically transparent manner includes a first DWDM system with a first optical line amplifier (OLA) for amplifying the signal to be transmitted and a second DWDM system which has a second OLA for amplifying the signal to be transmitted. The first OLA and the second OLA are connected to each other via a passive N×N AWG, arrayed waveguide grating.
