Infineon’s standard 4-band VDSL (4bVDSL) is a
highly integrated chipset designed for VDSL
DSLAM/Line cards and CPE applications.
VDSL is a robust, fully standardized technology.
Infineon’s 4-band 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 ATM VDSL chipset implements QAM
modulation, as defined in the VDSL standards. Its
spectral allocation enables coexistence with voice
and ISDN services on the same line, as well as
with other xDSL technologies in the same bundle.
VDSL is an excellent way to speed up broadband
services for residential, business and commercial
environments. A typical VDSL application is the
“Last Mile Network” that offers high resolution
video, high-speed Internet and advanced tele-
phony services over a single twisted pair.
