FTTx Marketing & Technology Trend
Summary
 Implement FTTx need to Leverage Triple Play
Service Values with Existing FO Cable OSP
 Video Services including VoD/IPTV shall
dominate FTTx Product Direction
 FTTx industry shall be at initial stage
 FTTx integrates with QoS, Security, High
Bandwidth throughput shall become major
factors for NGN services
