L. K. Vanston, R. L. Hodges, and J. Savage, "Forecasts for Higher Bandwidth Broadband Services", Technologies Futures, Inc.

• With 24-48 subs per ONU, PON should have 10 Gb/s capacity

MSOMSO MarketMarket

• MSOs are looking for post-DOCSIS 3.0, all-fiber solutions

Wireless BackhaulWireless Backhaul

• Desired accesspoint density makes

• DOCSIS 3.0 can provide a total of 5 Gb/s

• The EPON architecture is a

PON the onlyfeasible solution

• 4G Wireless requires up to


The EPON architecture is a perfect match for the MSO networks, but more bandwidth is needed

1 Gb/s per access point PON capacity of 10Gb/s is needed
