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

4/20

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

subscribers home

Interoperable with any OLT vendor

Why GPON Tester?

Traditional test and measurement equipment is not sufficient forGPON/FTTH networks

Power meters only report the power of downlink. Do not reportproblems 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 isrequired. It doesn't give information about GPON service level.

The use of a "testing ONT" does not ensure proper installationof 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
