How to Mitigate xDSL Noise (Webinar in Italian)

  • October 31, 2014

Alfonso Domesi

Regional Product Line Manager

Alfonso Domesi started his career in the telecommunications market in 1991 as a hardware and software development engineer. Over the years, he has tracked the evolution of transmission technologies over copper pair, from the first voice frequency analog modem to the latest high-speed VDSL2 devices and their corresponding QoS measurement systems. He currently holds the position of EMEA Regional Product Line Manager, with a dedicated focus on assessing new markets and technologies for EXFO’s FTTx Wireline product portfolio.

Access networks: FTTx, xDLS, triple-play

Come mitigare le problematiche del rumore su xDSL

I servizi DSL sono molto più sensibili alle interferenze rispetto alle tradizionali linee telefoniche. Il rumore ad alta frequenza (o banda larga) può causare interferenze o freeze dell'immagine nelle trasmissioni IPTV e rallentare o rendere intermittente l'accesso al web. Ciò richiede un'efficace riduzione delle fonti di rumore. 

Per rilevare il rumore a banda larga e raggiungere le prestazioni attese è necessario impiegare tecniche di misurazione appropriate. Recenti sviluppi nelle tecnologie xDSL, incluso il bonding e il vectoring VDSL2, rendono di importanza ancora più critica una conoscenza completa delle odierne reti ibride e FTTx.

Questo webinar esamina gli effetti del rumore sulle prestazioni del servizio DSL e mostra come procedere per rilevare e individuare le fonti comuni di rumore che influenzano i servizi VDSL2 e ADSL. Il corso descrive inoltre le prassi migliori per la caratterizzazione dei doppini di rame e la convalida delle prestazioni VDSL2.
