FTTX


           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!
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 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
