Technical Objectives This work examines
the technological requirements and assesses the performance analysis and feasibility
for implementing several novel architectures that integrate both WDM-PON and
RoF networks, for the delivery of
bandwidth-intensive integrated voice, data, and video services at distances
beyond 20 km in the subscriber access network. It is expected that the proposed test-bed
will enhance the access network�s capabilities to ensure that real-time voice
and IP video services can be delivered over a single platform with the same
QoS and ease of management as ATM or SONET. The inclusion of RoF technology will
provide a wireless interface that can extend the transmission distance
compared to coaxial cable, and can offer secure communications, low power
consumption, as well as simplified antenna configurations. We will define the proposed
self-healing architecture, as well as the distributed fault detection and
recovery mechanisms. The proposed architecture and protocols will be
experimentally tested to provide an analysis of the recovery time, as well as
to ascertain the scalability of the proposed architecture when the number of
optical network units (ONUs) (for fiber-to-the-home) and RoF picocells (for wireless last mile delivery) are
increased. The proposed test-bed will also provide the capability to: (a)
test the performance of new RoF picocell architectures,
and new devices and subsystems in a realistic configuration (b) examine the
interplay between the wireless channel and the optical layer and (c) test a
host of applications (such as uncompressed HDTV signals) through the network
architecture.
