Telson I&C, a Korean networking equipment supplier, has designed its new XV4000 broadband access system using Infineon’s QAM-based VDSL5100 chip set to support 50/30 Mbps data rates and dynamic band allocation as specified in the Benchmark Test requirements of Korea Telecom. Telson is one of the main suppliers of VDSL equipment to Korea Telecom (KT). Telson claims to have over 800,000 ports already installed in KT’s network, all of them powered by Infineon’s QAM-VDSL chip sets.

- Earlier this month, Infineon Technologies introduced a new Modem-on-Chip (MoC) solution for access line card and customer premises equipment (CPE) designs. Infineon’s chip incorporates the digital transceiver, analog front end (AFE) and line driver for a VDSL modem. The new VDSL5100i chip also features Infineon’s Adaptive Hybrid technology, which enables filterless designs, thereby reducing the number of external components and associated cost, for both line card and CPE devices. Infineon said its VDSL chip provides an aggregate data rate of more than 100 Mbps, including asymmetric data-rates of 70/40 Mbps and symmetric data-rates of 50/50 Mbps over single-pair copper wires. It also features a software-controlled band plan and transport protocol selection for both native Ethernet as well as ATM traffic. Infineon claims its Long-Reach technology, which utilizes Band 0 frequencies, can extend the range of VDSL services to up to 13,200 feet (4 km).
- Separately, Infineon announced that Huawei Technologies has designed a multi-range VDSL system based on its new QAM VDSL5100 chip set.
