Ikanos Announces 100 Mbps Symmetric over Copper

Ikanos Communications announced a programmable chipset capable of delivering speeds of up to 100 Mbps in both upstream and downstream directions over a single copper line at distances under 3 Kft (0.9km). The increased bandwidth capabilities are attained using advanced signal processing techniques and extended frequency spectrum -- up to 30 MHz, compared with 12 MHz in VDSL and 2 MHz in ADSLx.

The rollout include a chipset designed for Optical Network Units (ONUs) and Optical Line Terminals (OLTs), and another designed for Subscriber Located Equipment (SLE) and Optical Network Terminals (ONTs). Both products, which are part of Ikanos' Fx family of chipsets, support symmetric bandwidth of up to 100 Mbps in 64 Kbps increments. A carrier would use existing copper pairs extending from the ONTs to deliver high bandwidth services.

Significantly, the Ikanos chipset features programmable band plans, enabling equipment vendors to turn specific bands on and off to comply with standard specifications. The chipset also can reduce power levels in bands to minimize noise in the cable binder. This enables co-existence with deployed DSL technologies, especially for in-building deployments where multiple DSL technologies might be present in the riser.
