In the 1980s and 1990s, optical communications revolutionized long-haul transmission. Today, the long distance and underwater communications are the backbone of every major provider consisting of optical fiber. The technology has shown to be vastly superior to copper in terms of bandwidth, range, con- sumed power, longevity and reliability. Recent advances in the manufacturing and commercialization of Passive Optical components are now extending these capabilities to the edge and campus networks. Buildings that have been traditionally wired with CAT 5/6 copper are facing a fantastic opportunity from the emergence of Passive Optical local-area network (LAN) technology along the same lines as: reduced infrastructure footprint and costs, reduced power requirements, future-proof bandwidth, greener infrastructure, safer and higher security and better reliability.
