In Late March 2012, the GreenTouch Consortium announced and demonstrated a new technology that will dramatically reduce energy consumption in fiber-to-the-home (FTTH) networks, as well as other applications. The breakthrough Bit-Interleaved Passive Optical Network (Bi-PON) technology is the second major milestone reached by the consortium. When deployed, it will enable a power reduction of 30 times over current technologies while improving performance and reducing cost.

4. Today’s News: Breakthrough Tech for Wireline
• The Problem: In current fiber-to-the-home architectures, all data is
processed but 99% is unused
• With FTTH expected to nearly double over the next five years—to 142
million subscribers worldwide—energy consumption is a major concern
• GreenTouch Solution: New bit-interleaving passive optical network (Bi-
PON) technology, which can reduce carbon footprint equal to taking half
a million cars off the road
• Bell Labs, IMEC, INRIA and Orange collaborated in GreenTouch Wireline
Working Group to demonstrate how Bi-PON can improve energy
efficiency by more than an order of magnitude over current technology.
