WP5

Objectives

WP5 is a demonstration work-package, which will be active during from month 16 onwards. The POF-ALL technical research results obtained in WP1-WP4 will be demonstrated over real application systems on two different test-beds: the Fastweb network test-bed at ISMB and at Fastweb internal sites, and the POF-House test-bed at POFAC. This will require interfacing the POF transmission prototypes realized in WP1-WP2 with commonly used network transmission protocols, i.e., mainly with Ethernet. Moreover, this WP will show pre-commercial implementation of some of the best solutions coming out from WP1-WP2 and, if feasible, an introduction of POF system in a part of the FastWeb network.
In order to prepare the construction of the testbeds, required components will be built and tested during the second year of the project.

Description of work

One aim of test-beds is to have a test option under different environmental conditions and with different real-word network applications, with a specific emphasis on Ethernet compatibility. In fact, the availability of Ethernet-compatible prototype will allow testing the prototypes themselves over which different real-word applications (such as video streaming). The second aim is to demonstrate under real conditions the functionality of broadband solutions.
Fibers and components will be developed, characterized and tested in the other work-packages. Every test-bed should be a common test environment for different combinations of components with comparable and realistic parameters. Key elements of the test environment are the measurement setups available at POFAC:
• Bit error tester for bit rates up to 2.7 Gbit/s (plus 4 channels with 660 Mbit/s available for cross-talk measurements in parallel and bidirectional connections)
• climatic chamber for tests under low/high temperatures and humidity
• broadband optical receivers and high speed oscilloscope for eye diagram analysis
• near and far field analyzer for the measurement of mode distribution
In addition to measurements of bit error probability and eye diagram, systems will be tested with several protocols (mainly Ethernet and IEEE1394) and applications (mainly video streams, which are by far the most demanding applications). Depending on the application, parallel channels or bidirectional transmission is required. Delay times and jitter are specific parameters to be measured for these cases.
Test-beds will enable the measurement of the realised components with new fibers, which will be developed during the run time of the project.
To demonstrate the applicability of the developed systems in real environments, practical applications shall be used. Such a possibility exists in the “Nuremberg POF-Demo Apartment” and in the planned “POF Demo House”.
Another important contribution to test and demonstrate will be given by Fastweb, that will try to check and demonstrate the compatibility of the systems developed in POF-ALL inside its access network. This work will comprise several activities to be carried out in a real Fastweb environment:
• Installation of POF switches and media-converters.
• Check of all connections and compatibility with Fastweb transmission parameters
• Planning of preliminary compatibility test in-field
• Selection of some customers for real installation test towards final user
• Implementation of preliminary compatibility test on Fastweb webfarm and by selected customers.
• Feedback from the system integrator on the ease and practicality of the connectorization and mechanical splicing of active and passive POF components.
• Analysis of test report to start the validation procedures in our test lab of active and passive POF components.
In parallel, a validation activity will be carried out, following the standard validation procedures that Fastweb applies to new system and subsystems prior to the introduction in its network. In particular:
• Definition of validation parameters on POF systems at 10 and 100Mbit/s and on passive and active components integrated in our access network.
• Installation of active and passive components on test validation line.
• Implementation of validation test in regard to quality and performance transmission of Fastweb supply services on the compliance of our network validation and network management specification.
• This validation tests are implemented on components in stand alone and integrated on our access network
• Test reports Analysis of stand alone or integrated components.
• Validation and approval report of active and passive POF components.
Fastweb-related demonstration activities will also be carried out in ISMB, where a “copy” of a FTTH Fastweb residential installation is present.
