Infineon鈥檚 standard Packet over VDSL (PoVDSL)
provides Ethernet transport over standard QAM
VDSL. The chipset provides an xMII interface
allowing 鈥減lug and play鈥?connectivity for
Switch/Line cards and CPE applications.
VDSL is a robust, fully standardized technology.
Infineon鈥檚 packet based VDSL system solution
delivers transmission speeds exceeding 65 Mbit/s
1)
.
It also provides symmetric 16 Mbit/s or asymmetric
26/3 Mbit/s broadband services at a distance of up
to 5000 ft (1500 m) over existing copper wires.
Higher rates are possible with reduced ranges.
Infineon鈥檚 PoVDSL chipset implements QAM mod-
ulation, as defined in the VDSL standards. Its spec-
tral allocation enables coexistence with voice and
ISDN services on the same line, and with other
xDSL technologies in the same bundle.
Packet over VDSL provides fully integrated copper
access technology with high resolution video,
high-speed Internet and advanced telephony ser-
vices over a single twisted pair.
