Abstract
In this paper we investigate the current status of Fiberto-
the-Home Passive Optical Networks. We start by
reviewing the driving forces behind the push for
broadband from the customer and service provider
sides. PONs are currently preferred for new FTTH
deployments for a variety of reasons; we review their
standards, new technologies and deployment plans in
the United States, Japan and Korea. We then describe
SUCCESS-HPON, a next-generation optical access
architecture that allows a smooth transition from TDM
to WDM-PON. We finalize by summarizing what we
believe are the main open research issues in this area.
Keywords: FTTH, PON, WDM-PON.
1. Introduction
The driving forces for Fiber-to-the-Home/Curb/Node
(FTTX) technologies in the telecom business can be
better understood by briefly reviewing the history of
broadband access. Traditionally, the two most
common electronic communication services have been
standard analog broadcast or cable TV and Plain Old
Telephone Service (POTS). These two services were
provided by separate infrastructures that coexisted
peacefully for many years. The advent of the WWW
created a marked increase in the demand of home data
communication services. Starting about a decade or so
ago, ILECs and MSOs started satisfying this demand
in the form of Internet dial-up and DSL services the
former, and HFC cable-modem services the latter, and
thus started competing directly for customers.
The bandwidth offered by DSL and HFC
networks has been enough for users’ demands for
now. However, the nature of the traffic that flows
through the Internet is changing. New applications
require higher bandwidths, support for constant-bitrate
(CBR) streaming media, symmetric data rates
(e.g., for peer-to-peer file transfer), low delay for
interactive applications and security. The Internet,
originally designed to provide a best-effort service and
make use of statistical multiplexing, will need many
architectural upgrades in order to accommodate these
new demands [1].
