NGAN DAA (Next Generation Access Network - Distributed Access Architecture) is a unified Comcast Core Network platform which enabled digital transformation and orchestration of Fiber Optics cable modem.

It transforms networks into agile platforms for service delivery, leveraging disaggregation and open source to build innovative solutions for operator networks and catalyze our industry to accomplish this transformation.
Fiber Deep improves network performance by reducing the homes per node ratio placing fiber closer to the customer.

It positions us for long-term bandwidth growth utilizing smaller service groups.
