    New services require more bandwidth Internet Multicast/Video (HDTV) Gaming/Gambling

    You are spending most of your OPEX/CAPEX on FTTx toprovide this additional bandwidth

    Why FTTx?

    If you own the whole network, or a part

    of the network, you need QoS Strategy

    Ensuring Quality from FTTx Manufacturers

    Several operators now insist on strict continual demonstration of reliability andenvironmental stability

    Cost of failure given the geographical diversity of the deployments would be huge Element costs are under tremendous pressure

    PON Network TestingTurn-Up

    Before activating the network or when connecting an ONT:

    -

    Optical power measurement at the CO to ensure that sufficient power is delivered to the ONTs- Optical power measurement at each splitter output- New ONT = downstream and upstream optical power measurement at the drop

    FTTH Test Challenges and Solutions

    Connection check / Continuity check on high fibercount FTTH

    Connector is the #1 issue on FTTHnetworks

    Requires training, cleaning tools andeventually connection check withmicroscope

    High fiber count on distribution generatecontinuity check issues

    Requires automated measurementstools with continuity check functions

    Bidirectional loss test sets Bidirectional OTDRs OTDR with a termination

    receiver at the other end

    Copper Construction Acceptance Testing/Pair Qualification

    - Good pair Check of Voltage, Resistance, Pair Balance, Loads- TDR test from MDF to Crossbox to Pedistal (feeder qualification)- xDSL Rate/Reach qualification

    IPTV Network TestingTurn-Up

    Before activating the network or when connecting to an Ethernet port of an ONT:

    - Emulate set top box and receive multiple video streams- Channel Change Time, VOD transaction- QoS measurements, and V-MOS

    VOIP Testing

    Before activating the service or when connecting to a Ethernet port of an ONT:

    - Verify service set-up/provisioning and registration with gateway- Place test calls on and off-network- Ensure Call Quality and MOS for active test calls

    Costly to dispatch tothe home to fixissue

    Resource intensiveto solve issues dueto lack of remotetest & trouble-

    All-in-One Test Set Reduce the number of tools that must be

    purchased and maintained for installationand service calls

    Reduce technician training time needed tolearn multiple test platforms

    Integrate all test reports into one easy-to-read report

    Reduce costs by eliminating redundancyfrom the above examplesA single test set can test the serviceand access layers as well as performin-home measurement and anaylsis.
