Infineon’s standard Packet over VDSL (PoVDSL)

provides Ethernet transport over standard QAM

VDSL. The chipset provides an xMII interface

allowing “plug and play” connectivity for

Switch/Line cards and CPE applications.

VDSL is a robust, fully standardized technology.

Infineon’s packet based VDSL system solution

delivers transmission speeds exceeding 65 Mbit/s¹⁾.

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’s 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.
