100GbE- Optical LAN Technologies [Applications & Practice]

Abstract

This article discusses optical and IC technologies feasible for use in the development of LAN interfaces based on future IEEE 100-gigabit Ethernet SMF and MMF standards. SMF approaches using 10-Gb/s and 25-Gb/s WDM, and DWDM WAN technologies are outlined, with the 25-Gb/s approach examined in detail. The MMF approach using 10-Gb/s parallel optics technology is also examined in detail. Future technologies required for high-volume, low-cost 100 Gb/s are previewed.
