3. Benefits Technician and Installer
GPON Tester is the ultimate tool for installers,
network maintenance technician of GPON/FTTH
networks
– Easy to use: test and diagnosis with just one button
– Accurate: Identifies the presence of problems in the optical
performance and/or GPON service
– Fast: Certify an installation in 2 seconds
– Portable: 900 grs.(including batteries)
– Robust
– Cheap

4. Benefits for the operator
CAPEX Reduction
– Faster and more reliable FTTH deployments
– It is not necessary that the installer has specific expertise in
GPON
– Homogenization of the protocol of certification of an installation
– No need of Power Meter, OTDR, ONT, etc
OPEX Reduction
– Fast and accurate identification of the origin of the problem
– It is not necessary that the "expert " in GPON moves to the
subscriber’s home
– Interoperable with any OLT vendor

17. ¿Why GPON Tester?
Traditional test and measurement equipment is not sufficient for
GPON/FTTH networks
– Power meters only report the power of downlink. Do not report
problems in uplink. Nor measure the presence of reflections in the first
meters of fiber in the home (mechanical connections, dirty connectors,
bad connections).
– The OTDR, besides being expensive, is not easy to use. Training is
required. It doesn't give information about GPON service level.
The use of a "testing ONT" does not ensure proper installation
of a subscriber or provides diagnostic information.
– It is possible that an ONT sync out of optical budget
– Do not generate reports to certify the installation
– Can not program the length of the test and provide BER data
