3.1 Why FTTH, Why Now?

3.2 How much bandwidth do we need?

3.3 Why GEPON, not GPON?

3.4 Economical cable network configuration?

- Centralized or two stage Splitter?

-Air-blown or conventional duct cable system?

3. FTTH Deployment Considerations


22/31


3.1 Why FTTH, why now? --FTTH is the most future proof solution


23/31


Nielsens law:

Annualized growth rate

of internet bandwidth is 50%

Moores Law is that the CPU speed

increase 100% in 18 months.

3.2-1 How much bandwidth do we need?

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.

+KT has started FTTH mass deployment with GEPON.

+GE-PON is used in large scale field trials in China, Philippine,

Taiwan and Thailand.

GE-PON

G-PON

+B-PON is now popular in USA and Europe.

+G-PON is not widely used yet.

Verizon selected G-PON venders.

+G-PON is now much expensive than GE-PON.

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


31/31


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
