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!

What is FTTx?
• 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 TelcosIn 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

Why FTTx? Why Now?
• 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?

Who Wants FTTx?
• 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!
• Data from Render, Vanderslice 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 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

FTTx Is Driving Residential Cabling
• Driven by FTTH, building codes, customer demand and builder profits
• More diverse than commercial cabling– Internet– CATV coax– Home theater– Intercom– Security
• TIA 570A+

The FOA Supports FTTx
• New certification for FTTx techs
• Training program and reference materials for FOA-approved schools
• Helping recruit FTTx techs
