E-PON Technology and Markets
PracTel Inc, May 2005
This report reflects the analysis of the newly adopted IEEE 802.3ah standard for Ethernet Passive Optical Networks. The market reacted very positive to this standard acceptance, and E-PON is a welcome newcomer into a group of PON technologies.
E-PON came to the picture after establishing the FSAN group of standards, and its timing reflects the importance of the Ethernet technology:
- Ethernet became an official data standard
- “Ethernet everywhere” concept is being implemented, and proliferation of the technology extends from desktops to core networks
- E-PON keeps all major features of Ethernet
- It is particular advantageous to use in the Internet environment.
With this in mind, we developed the report, which, as far as we know, is the first such document dedicated fully to E-PON. It consists of the two major parts – the technology and the markets. In the technology part, we provided a comprehensive picture on the current status of PON technologies. We emphasize the wide spectrum of issues, and showed E-PON as a technology that has many features standard to all PONs as well as a number of distinguished properties. The heart of the E-PON standard is the Multi-Point Control Protocol, which was developed specifically for this technology. With its help, the E-PON OLT orchestrates all network operations, and provides the required network algorithms.
We also attempted to compare E-PON with previous standards, which is not a trivial task. We provided comparative analysis of technologies, but left to the providers to decide in each particular case what exactly is advantageous for them.
In the marketing part, we estimated the E-PON equipment and providers’ revenue markets as derivative of the total PON market. Our estimate proves that the E-PON market, though still very young, shows all symptoms of the strength, and in many cases E-PON will push B-PON and G-PON aside.
Target Audience
This report is important to a wide population of researches, technical and sales staff involved in the developing of the PON services and products. It is recommended for both service providers and vendors that are working with related technologies. The report also helps to understand issues associated with relationship between E-PON and other technologies.
