South Korea FTTH and Broadband Deployment


1.87 million subscribers in March 2009> 2 million in 20101.87 million subscribers in March 2009> 2 million in 2010

� KT provides voice, data, and digital video using GE-PON, similar to NTT

� 1x4 splitter at Central Office

� 1x8 splitter at Pole

� Customized drop cables use field assembled connectors and plug directly into customer ONU

� Telco service provider and other service providers are deploying using similar connector

� One is SC/PC, other is SC/APC

Motivation for New Horizontal Pathway Solution:

� High Labor costs to install traditional cable routing

pathways such as crown moldings or plastic wire

moldings

� Multiple steps to create pathway and to route fiber

� Congested pathways or conduits that are typically

shared between multiple operators (CATV and Telco)

� Poor aesthetics of current big, bulky solutions

MDU deployment costs are: 46% Labor, 42% Actives (2 6% CO, 16% Subscriber) and 12% Materials

Verizon is now deploying Flexible DuctSolution & planning to use mechanical connector

36



1. Make window cut into already installed duct. 2. Select colored fiber for drop to tenant.

3. Fasten Point-of-Entry Box to wall and drill hole into living unit. 4. Field terminate with 3M NPC connector..

5. Insert connector into adapter.. 6. Add drop cable to living unit ONT.. 7. Snap on cover to complete..

FTTH Global Summary

� Japan is a leader for FTTH deployment

� Korea is moving quickly

� North America, mainly Verizon and small telcos, are

deploying

� Verizon uses factory terminated drops for single family, but

are moving toward mechanical connectivity for multi-dwelling

units

� France Telecom has deployed, but has slowed due to

regulatory issues

� Japan, Korea , and France along with much of the rest of

world uses mechanical connectivity at the drop

� > 70% of global drops use mechanical connectivity
