Next generation PON changes the role of fibre

GPON XGS-PON

Home entertainmentVideo is the main driver

8K and VR devices replacing 4K

New services (web scene, holo-chat)

Businesses Cloud drives uncompromised bandwidth requirements to and in the campus

Smart cities90% of smart city security connections will remain wireline (despite 5G) for high definition video (face recognition)

Complement 5G deploymentsEnhance coverage

Efficiently 5G transport

Converge all services on fibreReduce OPEX with Pre-aggregation of remote copper, coax, fibre nodes

3-play

From fibre to the home to fibre to everything

Optimizing introduction of XGS-PON

Improve network efficiency

• Save cost in fibre feeder with higher split ratio

• Reduce OPEX by running one network forall services

• Introduce Wi-Fi6 for better in-home coverage, lower latency and mobile offload

• Automate and simplify with SDN

Greenfield: Start with XGS-PON

• Small cost difference

• More revenues

• Future proof

• Competitive advantage

25G PON initiative supported by 18 ITU-T members:

Public

25Gb/s is accepted as a critical step by the industry

All standards have 25G step, except ITU-T PON

• Other standard bodies have agreed on 25G as a stepping-stone between 10G and 50G

• 25G is delivers a critical cost optimization

• 25G PON was proposed in ITU-T by 18 co-signers including regionally diverse T1 operators and vendors

• Politics interfered and the proposal was procedurally blocked
