What is FTTx?
•FTTH:
fiber to the home
•FTTP:
fiber to the premises
•FTTC:
fiber to the curb
•FTTN:
Fiber to the node
•FTTx: for those who can’t decide what to call
it or are referring to all varieties!
•Mostly
a telco
issue
–Telcos have many aging cable plants
–CATV companies have HFC networks in place
–Competitive carriers now install own
fiber
–Telcos fighting for exclusive rights
Who
Competes With Telcos In Implementing FTTx?
•Municipalities
•Utilities
•CLECs
•Private companies
•Battleground for telcos
and CATV companies
Where
is the fiber?
•Where
is the bulk of telephone cabling?
–10% is long distance
–10% is local loop (metropolitan)
–80% is subscriber loop
•Long
distance and local loop are virtually all fiber
•Is
FTTx
just completing the system?
Why FTTx?
Why Now?
•Telcos are suffering with aging copper cable
plants
•Telcos are losing broadband customers to CATV
and landline customers to cell phones and VoIP
•New
services are becoming available to enhance revenue - and customers demand them
•Regulations
changed sharing issues
•New
technology (PON) and cheaper components makes FTTx cheaper
•Many
telcos
are realizing that the alternatives to FTTx are inadequate for future bandwidth
needs:
–DSL won’t have the bandwidth
–Wireless won’t have the bandwidth
–BPL won’t have the bandwidth
•Eventually
they will have to go FTTx, so why put off the inevitable?
•Homeowners:
for high speed Internet access and video downloads
•Home
Builders: FTTx
adds value (and profit) to their homes
•Hardware
Providers
•Service
Providers: IPTV, HDTV, video on demand
FTTx is gaining momentum
•US:
6 million homes passed (Jan, ‘06)
•1,000,000
connected
•Still
a drop in the bucket!

and Associates, 2006
What’s
In It For Contractors?
•Contractors are doing FTTx installs for Verizon and others
•While few electrical contractors do residential electrical, homes with structured cabling offer double the work and potential profit!
•FTTx will affect the commercial fiber market - fiber is cheaper!
FTTx Cost Breakdown
FTTx Architectures
•Home run - fiber from CO to every home
•Active star - local switch then fiber to every home
•Passive optical network (PON) - use splitter near customer share fiber to CO
•WDM PON - PON but with each customer having a specified wavelength
•All based on standard SM fiber
