| description | The access network growth has been a hot topic in recent telecommunication
industries. Either in its applications, bandwidth offered, speed of data
transferred or even the techniques used to achieve network growth. Many
researchers have investigated this problem and come out with many
solutions which are used in today's network in variety of applications and
services.
As the number of user and bandwidth grows, current network is incapable of
managing the bandwidth demands. Another problem that limits this service
is the availability of services in places far from the exchange office.
This thesis proposes a new system with a new architecture to be
implemented in the access network in order to solve this problem and provide flexibility in expansion the current network or system without
intervening it. The proposal involves cascaded multiplexing technique which
is based on Coarse Wavelength Division Multiplexing (CWDM). The
cascaded multiplexing structure allows easy extension of the coverage span
and CWDM provides asynchronous multiplexing at a considerably less cost
than the DWDM version.
Simulation and experimental work have been done in order to develop and
test the system proposed to maximize the utilization of fiber, improve the
performance, and increase the distance of transmission and the bandwidth
support. This system is also studied in different formatting schemes and
integration with amplifier. The proposed system can support the data
bandwidth up to 2.5 Gbps with the maximum network coverage about 17 km
in radii and optimal wavelength spacing of about 2 run (after consideration
of wavelength shifting and laser spacing). |
