3.3-1 Why GEPON, not GPON?
1) Servicesa) High-quality IP Telephone and IP video are becoming important Basic
FTTH services
b) Leased line users are shifting to less expensive Ethernet Leased Line.
2) Networksa) Full IP backbone networks for B-FLETs & NGN
b) Switches & routers in the network employ Ethernet Interface
No need to employ ATM.
EPON is very suitable for IP networks and IP services.
3) Systema) In terms of quality and reliability, Carrier-grade GEPON has been realized.
EPON is the optimal FTTH system for the future.

3.3-2 GE-PON vs G-PON
+GE-PON has been widely used for more than three years
in Japan and now there are more than 4 million GEPON
subscribers.

+GE-PON is used in large scale field trials in China, Philippine,
Taiwan and Thailand.

+B-PON is now popular in USA and Europe.
+G-PON is not widely used yet.

3.4.2 Air-blown and conventional duct cable system Comparison
High Cost in: Subducts & Fiber Units, Multiple Connecting Accessories & Tools and
Operational Cost
In-Building Blown Fiber: For Fiber Blown directly from MDF to each Customer Premise,
large riser space is required. Huge wastage!
Currently only 1 standard (IEC 60794-5) for Air-Blown Fiber and Cable. Blown Fiber DO
NOT meet GR-20 environmental and tensile specifications
Fiber unit specifically designed for deployment in UK only thus environmental protection
for installation in other countries is lacking
2x Installation is required thus 2x the cost! : Fiber Tube Installation Fiber Unit
Installation (Unused fiber tube needs to be sealed)Repeated installation increases man-hour and logistical cost (Many times more expensive
than the cost of fiber)
Reasons why many Telecom Operators DO NOT adopt Air Blown Fiber System

4. Summary
1. FTTH is being deployed massively in Japan, Korea, USA and Europe.- PON is used widely in Japan, Korea and USA.
- P to P is used widely in Europe.
2. Commercial FTTH deployment has started in many countries in Asia and Middle East.
- One big issue is the choice to deploy GEPON or GPON
- IPVPN over GEPON is very popular in Japan.
3. Premise wiring is a big portion of the installation cost so that new technologies have been
introduced to reduce installation time and cost
4. Worldwide, increasing number of networks and services are shifting to IP Ethernet
5. FTTH is currently the Future Proof High-Speed Broadband Network
