[WP1] [WP2] [WP3] [WP4] [WP5] [WP6] [WP7]Objectives
The objective of this WP is to identify and choose the
optimum large-core POF for the planned applications. This goal
shall be achieved by a profound survey, supported by extensive
characterization of all currently available POFs, and by a
production of specifically designed test samples.
Description of work
The objectives of this WP4 are three-fold:
In the 1st phase POFAC will provide other partners in the
consortium with a review of the state of the art of large core
POF (core diameter > 500 micron), together with a comparison
with competitive fibers such as glass fiber (GOF) bundles and
polymer clad silica (PCS) fibers. This study will strongly
affect subsequent technological choices to be made in WP1 and
WP2. It will be constantly updated throughout the whole duration
of the project.
Based on this information, a limited number of candidate fibers
will be selected for complete characterization (spectral
attenuation, bandwidth, numerical aperture, bending sensitivity,
mechanical properties, index profile etc.) which will be carried
out in the 2nd phase by POFAC and Luceat (depending on the
measurement facilities correspondingly available).
In the 3rd phase the optimum fiber will be identified based on
the results available from WP1-2, taking into account the need
for high bandwidth on one side (i.e. small detectors, small core
diameter, low NA) and ease of handling on the other side (i.e.
large diameter, large NA), not to forget a low target price.
This fiber will be a trade off and if not commercially
available, at least test samples will be developed and
manufactured by Luceat.
This WP will be led by POFAC, which has a long experience in
fiber characterization. LUCEAT will participate to give its
expertise on long distance POF systems, on feasibility of
different fiber types and on long term reliability tests on POF
on the green and red wavelength windows.
Fastweb will participate in this task to check the
compatibility of passive component and fibers using its internal
validation processes. Items under test will be:
• Connectors plug and socket
• Mechanical splice
• Fiber management in access cabinet
• Fiber management in customer house
• Fiber management on devices and access network.
This check will be realized testing all items of access network
with POF passive components, that can be find on the global
market. For each of this new fiber and components, FastWeb will
test:
• Mounting test to check the ease field mounting and the correct
functionality in the time. The goal of this check is to bring
out components that can improve the installation quality to
reduce the operation cost of the broadband operator.
• Optical functionality test of transmission to check the
attenuation of plug and socket connector and mechanical splice.
• Optical functionality test of transmission to check the
attenuation of fiber management on static and dynamic handling
condition.
• Final analysis of the test report and select the best
components in according of the requirements
