~92M GPON ONTs will ship in 2016

In 2010, GPON ONTs numbered ~4.3M globally

CAGR of 84.2% from 2010–2016

An unqualified success, but it wasn’t always that way

It has taken time for success… almost a decade

GPON transceivers were initially considered too complex to build economically

The global momentum is impossible to ignore

GPON has been a success for residential and SMB services

ONT shipments are expected to plateau in next year or so… why?

Features and benefits

10G/10G fixed wavelength standard

Leverages lower cost optics similar to 10G EPON optics

Support for XG-PON1 (10G/2.5G standard) via dual burst mode receiver

10G PON price-performance “jump-in” point for late 2016/early 2017 deployments

Coexistence with current technologies

Limitation and challenges

Single wavelength limited to useful capacity of 8.5 Gbps (use of FEC is mandatory, though operators may choose to disable)

Evolution to higher rates requires new technology – NG-PON2 overlay

The “S” is for symmetrical

Proprietary and Confidential

Features and benefits

Multi-wavelength standard: 4–8 wavelengths of 10G TWDM PON

Tunable ONU optics enable: load balancing, capacity growth, high availability operations

Channel bonding extends service capacity to 20, 30, … theoretically up to 80 Gbps

TWDM and point-to-point (P2P) wavelengths

Coexistence with XGS-PON and current technologies

Limitation and challenges

Capital costs, though this may be offset by multi-wavelength operational savings, and market demand

Technical challenges in achieving fast tuning times – but we’ll get there
