Ethernet over VDSL Broadband access over existing copper

Ethernet over VDSL Broadband access over existing copper cables www. opticalaccess. com

Today infrastructure constraints • • Copper POTS lines covers all residential and business areas Other x. DSL technologies complex and not economical Other x. DSL technologies non-broadband oriented Ethernet over CAT-5 cable is limited to 100 m distance www. opticalaccess. com

Ethernet over VDSL • Ethernet over VDSL Ethernet link over telephone lines - Distances of up to 2. 4 Km using VDSL as the transport medium • Data rates of up to 10 Mbps, Full duplex, in parallel to the voice line (POTS/ISDN) www. opticalaccess. com

How does Eo. V work? • Ethernet over VDSL transmits 10 Mbps data over frequencies unused by the voice services POTS, BA-ISDN PSD [dbm/hertz] ADSL SHDSL -40 Eo. V -60 10 -80 <0. 12 Mhz 0. 9 Mhz Voice www. opticalaccess. com 10 3. 75 Mhz Data F [Mhz] 8. 0 Mhz
