Ikanos chips support 100 Mbps DSL

Ikanos has developed a new set of chips that support 100 Mbps DSL, based on a new standard that supports both channel bonding and vectoring.

Ikanos' new Fusiv Vx185 and Vx183 chips conform to the new G.vector ITU standard, which defines how to achieve 100 Mbps service over traditional copper lines, which by some calculations would be a tenth the cost of achieving the same transmission rates with fiber.

The standard covers bonding for increased rate and reach, ultra-low power and, ultimately, gigabit line rate performance.

These new devices add to Ikanos' NodeScale Vectoring architecture, which spans the central office, remote cabinets in fiber to the node (FTTN) networks, and now the customer premises.

The Fusiv Vx185 integrates support for bonding by natively interfacing directly to two integrated analog front-end devices, Ikanos said. This is designed to allow the coupling of two TCP (twisted copper pair) wires. Together, bonding and vectoring can be combined to push aggregate data rates up to 300Mbps, the company said.

The new Fusiv family of devices also includes the following features:

  • Full ADSL and VDSL2 support with a single hardware design
  • Support for all VDSL2 profiles and band plans for Asia, Europe, and North America – 8a, 8b, 8c, 8d, 12a, 17a and 30a
  • Support for ADSL2+, ADSL2, and ADSL standards
  • Support for all mandatory and optional features of VDSL2
  • Exceeds Broadband Forum performance requirements (TR-67, TR-100, and WT- 114)
  • Support for all wired or wireless networking technologies including Wi-Fi (single or dual-band concurrent modes), HomePNA, HomePlug, Multi-media Over Coax, and ITU G.hn
  • Integrated SATA interface for the easy addition of network attached storage devices
  • System level support for high performance IPv6
  • IPSec and Secure Sockets Layer (SSL) VPN implementation using on-chip cryptographic engines

John Quigley, president and CEO, of Ikanos, said G.Vector support "pushes VDSL performance to the 100 Mbps threshold and beyond at a time when service providers are looking for a cost-effective way to upgrade their existing copper networks in order to compete with DOCSIS 3.0 and FTTH technologies."
