Abstract

Keksinnön kohteena on menetelmä ja järjestelmä pakettivälitteisen tiedon siirtämiseen tietoliikennejärjestelmässä, joka käsittää reitittimen (R) johon on kytketty valokaapeli (LC), joka koostuu valokuiduista (LF), jonne lähetetään kaksi valon aallonpituutta, ja joka on kytketty tietoliikenneverkkoon (CN), jossa menetelmässä vastaanotetaan reitittimeen (R) osoitetieto valokuidun (LF) osoiteaallonpituudelta (AWL) ja vastaanotetaan hyötytieto reitittimeen (R) valokuidun (LF) hyötyaallonpituudelta (DWL). Menetelmässä reititetään hyötyaallonpituus (DWL) vastaanotetun osoitetiedon mukaan.&sr;(Fig. 1)
