PON vs. P2P Debate: The Next Generation
Ovum, Jan 2011, Pages: 12
Introduction
WDM-PON represents the ideal combination of technology and topology for FTTH, yet the prospect of commercialization remains remote. Ovum thinks the current domination of TDM-PON will continue for the next several years, with the initial 10G-EPON and 10G-GPON shipments likely to pick up momentum in specific markets. P2P will remain a niche market for residential access.
Features and benefits
- Explains the pros and cons of TDM-PON versus P2P
- Explains the connection to next-generation FTTH PON and P2P migration.
Highlights
- Among current-generation FTTH technologies, PON in general, but GPON in particular, enjoy advantages over Active Ethernet P2P.
- Over 2009 and 2010, GPON picked up considerable momentum, currently exceeding Active Ethernet P2P sales by far on a global basis. On a regional basis, the gap between the two differed.
- Among next-generation FTTH technologies, Ovum considers TDM-PON and WDM-PON to be evenly balanced with separate and sometimes overlapping pros and cons on either side. However, the lack of a timeline for WDM-PON standardization is a severe drawback that makes Ovum nominate TDM-PON the current winner.
Your key questions answered
- What are the pros and cons of TDM-PON versus P2P, versus WDM-PON?
- When will WDM-PON be commercially viable?
