pFTTx establishes ease for setting up common

NOC for shared Multi-vendor FTTx and significantly

reduces O&M Overhead

pFTTx establishes granular control over services &

subscriber isolations, paving the way for last mile

Security Policy Enforcement

pFTTx enables granular monitoring and control of policies to avoid

SLA violations, improve QoE Assurance, and Customer centric

Services
