ONU Benchmarking Service

Description

GPON test services aim to validate the functionality and performance of a GPON vendor solution. By benchmarking and certification, it will ensure that services can be delivered over GPON, and that no underlying issues exist with the GPON access layer, which under different conditions would cause a degradation in service performance. If the GPON layer is not tested thoroughly, but is just treated as a black-box, any underlying issues with the Vendor’s deployed GPON solution will be missed.

ITU-T standards compliance (G.984.3, G.984.4, G.988).
