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?

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

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

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.
