Abstract

En portstyrt optisk forsterker (5) for et passivt optisk nett omfatter en inngang for å motta et optisk signal som skal forsterkes, et utgang for utmating av et forsterket optisk signal, en optisk forsterkeranordning (11) for å forsterke et optisk inngangssignal til denne, en detektor (16) og en optisk svitsj (14) for å tillate det forsterkede optiske signal å forlate utgangen når detektoren (16) detekterer forekomsten av et optisk signal av en forut bestemt størrelse.
