P R O D U C T B R I E F Infineon’s innovative Octal-10BaseS chipset is a very high density 8-port 10BaseSTM solution for the design of switches and IP-DSLAMs. The chipset combines the structural simplicity of Ethernet with the high performance of VDSL communications. It supports transmission of 10 Mbit/s, full-duplex Ethernet packets over existing copper wires for distances up to 4000 ft. (1200 m). The chipset also supports transmission of legacy communication services without disruption. Ethernet PHY functionality is fully integrated into the Octal-10BaseS chipset for direct connectivity to standard Ethernet switching devices. Infineon’s VDSL technology uses frequency duplexing and QAM modulation to ensure robust operation. Its spectral allocation allows noise-free coexistence with other xDSL technologies in the same bundle. The Octal-10BaseS chipset is a very economical solution for distribution of broadband services in MDU/MTU markets and a most suitable solution for broadband LAN extension applications.
