•
WAN line utilization about the existing Internet
Narrow bandwidth between ISP and Home/Building
Slow Internet speed - Not provide enough services
High speed Internet -Demand high cost

What’s Broadband Network?
– Narrowband Network ／ Broadband Network
• It seems more and more likely to provide broadband
infrastructure and various contents for home/office users.
• We call the existing Internet connection “Narrowband”
on the other hand High-speed Internet connection
“Broadband”.

FTTH Technical Tips
– FTTH Access Network
• Gigabit/Fast Ethernet
– Transmit to home/building at 100M/1G speed using Ethernet
– This technology is matured and cost-effective.
– For the companies which don’t have fiber for themselves,
they need to rent fiber hence extra cost might occur.

How to design FTTH Backbone?
• Redundancy
• Type
– Chassis
» Hot Swapping
» Redundant for power supply and CPU
– Box
» Replacing with new unit
» Built-in redundant power supply or external redundant

How to design FTTH Backbone?
• Redundant Route
– Layer-3
• Only IP is used
• Defacto standard on the Internet
• BGP4
– Used as routing control on the Internet Backbone
– Provide every IP Route on the Internet
• OSPF
– Used by AS
– Applied to huge network dividing Area
• VRRP/ESRP
– Provide redundant default Gateway
– Share Virtual IP,Virtual MAC between devices

How to design FTTH Backbone?
– BGP4(Border Gateway Protocol version 4)
• Used by IX、ISP、iDC
• Provide Internet Full Route
– OSPF（Open Shortest Path First)
• Used for IP Router
