10BaseS
TM
is an innovative technology offering
the simplicity of Ethernet coupled with the high
performance of VDSL. Utilizing 10BaseS, a system
delivers 10 Mbit/s, full duplex Ethernet over
existing copper wire infrastructure up to a
distance of 4000 ft / 1200 m. It simultaneously
supports high speed DATA transmission with
POTS, ISDN or PBX signaling, without disruption.
Ethernet MAC and PHY functionality are integrated
into Infineon’s 10BaseS chipset, achieving direct
connectivity with standard Ethernet physical layer
and switching devices. Its VDSL technology uses
frequency duplexing and QAM modulation to
provide robust operation. Its spectral allocation
allows noise-free coexistence with other xDSL
technologies in the same bundle.
10BaseS is the best solution for distribution of
broadband services in MDU/MTU and hospitality
markets and the most suitable solution for
broadband LAN extension applications.
