3. Terminology
• AON Active Optical Networks (Against Passive
Optical Networks – PON)
• ARPU Average Revenue Per User
• CAPEX Capital Expense
• CPE Customer Premise Equipment
• FTTx Fiber to the X (Building, Curb, Home)
• ISP Internet Service Provider
• OPEX Operating Expense
• ROI Return on Investment

4. Why AON FTTx Networks for VNPT
• While VNPT has existing ADSL or FTTH networks to
provide internet (data) service, it needs to implement
manageable, more reliable next generation FTTx
networks quickly to be ready to
- offer triple-play service - data, voice (VoIP), and Video (IPTV);
- increase its ARPU via triple-play service;
- beat the competitions who only offer one or two broadband
service;
- provide more services like Wireless and IP Surveillance to further
increase its ARPU;
- deliver what it promises for bandwidth.

5. Why AON FTTx Networks for VNPT (Cont.)
• IP/Ethernet Active Optical Networks (AON) are market-
proven, cost-effective technology that has been
implemented in many marketplaces in the world. Even
the world-leading broadband service country like Sweden
also chooses AON FTTx Networks as a primary choice for
its broadband infrastructure
• PON can also be one of broadband infrastructure choices
in the future, but not now because it is
- not widely implemented;
- still quite expensive in terms of cost per port; high CAPEX;
- still with high OPEX.

6. Suggested Broadband Services Offered by VNPT
FTTx For Business Subscribers – offer 20M+
• High Speed Data service - powered by Ring Access Switch for data
• & Wireless & VoIP service - power by Wireless Copper Gateway for
additional data (Internet) & voice (VoIP)
service
FTTx For Premium Home Subscribers – offer 10M+
• High Speed Data & Wireless service - powered by Wireless Fiber Router
• Or High Speed Data, Voice, & Wireless Service – power by Wireless Fiber
Gateway
FTTx For Regular Home Subscribers – offer 2M or Lower
• Low Speed Data service - powered by Star Access switch for data
• Wireless service - power by Wireless Copper Router for data service

16. Why Loop Happens?
• Poor quality cables
• Wrong port installation by users
• Buggy devices
• Others – LAN card defect on Servers

17. Common Cable Installation Problems
• Use 4P4C Cable – ports are not connected firmly to cause
network down
• Install RJ-45 cable outdoor and device damaged by
lightning
• Use daisy-chain topology not Star or Ring – Ethernet Loop
• There are no structured cabling system

18. Device Damaged by Lightning
Warning
Do not install RJ-45 cable in outdoor; if outdoor installation is required,
use plastic fiber or 62.5/125 or 9/125 fiber together with fiber switches
Best solution – install RJ-45 cable indoor

19. Other FTTx Deployment Problems
• Too many complaints from partners and customers
because of unreliable access rings in the last mile
• No structured cabling in the last mile
• Unstable power supply
• Not enough skilled engineers to install, maintain, and
operate broadband networks
• Lack of quality support & service from manufacturers to
ensure smooth operations
• Some tailor-made functions & features required to meet
local operational needs
VOLKTEK has solutions to address these problems
