Fiber networks have the smallest carbon footprint of access network technologies
Fiber network technology is well established and proven
Fiber access network standards, e.g., ITU-T G.983 (1998), are over 10 years old – older than VDSL2 (2006).
In Japan alone there are 15 million FTTH subscribers
Fiber networks are highly reliable
In the 35 years since the first commercial use of fiber optics in telephony, fiber optics have demonstrated an extraordinarily high reliability.
Comprehensive testing programs like Verizon NEBS ensures product reliability
There is no known “wear out” mechanism for the passive optical plant.
I am frequently called about running current technologies, e.g. 40 Gb/s DWDM, on networks installed 25 years ago.
Fiber networks reduce operating costs
Verizon engineers reported to the Fiber to the Home Council that the lower lifetime maintenance of a Greenfield fiber access network had an NPV of $200/subscriber.
Verizon reports FiOS maintenance is 39% less than copper. OSP feeder and distribution alone is 91% less.
Fiber networks have the smallest carbon footprint of access network technologies
Fiber FiOS power consumption is 38% of copper DSL. Similar CPE, but 12 kWh/yr/line for FiOS vs copper.
NTT report “CO2 reduction of 57% by sharing an optical fiber”.

6. Fiber networks create infrastructure for Innovation and Investment up to and beyond the “100 Mb/s era”
Fiber is ready for the 100 Mb/s era today
Optical fiber access networks leverage current fiber product and invested Plant
Fiber networks are compatible with all other access network technologies
Fiber networks complement other access network technologies in cases they are a better solution
Fiber networks are the optimum baseline infrastructure for extending broadband and developing new and improved applications
Fiber is ready for the 100 Mb/s era today
Fiber network standards delivering 100 Mb/s and 1 Gb/s to the home have existed for years.
Products (including home terminals) to provide 1 Gb/s to the subscriber have existed for years
Optical fiber access networks leverage current fiber product and invested Plant
ITU-T and IEEE roadmaps are accommodated by the fiber networks being built today
Compatible with all other access network technologies
ITU-T standardizes PON interfaces to other access network technologies like Ethernet service, IEEE , xDSL, etc.
Complements other access network technologies in cases they are a better solution
PON application for wireless backhaul
CATV migration to RFOG/DOCSIS-PON
Optimum baseline infrastructure for extending broadband and developing new and improved applications
“Reach Extension” PON can deliver PON 60 km from the CO and increase split ratios to reduce operators’ costs.
WDM-PON and MPλS
BB served to low density populations with 3G or 4G wireless
Backhaul for xDSL extension devices
Low carbon footprint for these service models

Since 2004, the cost to deploy FTTH has dropped about 45%
It now costs network providers about $1,450 to bring optical solutions direct to your home.
Due to the adoption of new technical innovations we expect deployment costs to continue to decline to $1,300 by 2010.
Since 2004, the cost to deploy FTTH has dropped about 45% -- in other words, it now costs network providers about $1,450 to bring optical solutions direct to your home.
Due to the adoption of new technical innovations we expect deployment costs to continue to decline to $1,300 by 2010.
As a result, fiber to the home is becoming the preferred choice for most carriers as they expand their networks.

9. Fiber network products produced for FTTP Innovation reducing labor costs
The Solutions Group’s Factory Installed Termination System (FITS) is a field-proven technology. Fiber optic drop cables are factory terminated to a fiber distribution cable creating a plug-n-play system that eliminates installation steps in the field. Quality is also improved because the entire FITS system is tested before cable reels are shipped. The cost of deploying fiber optic cable in the local loop can be significantly reduced. FITS Features: • Reduced total cost of ownership • Quick deployment allows rapid turn-up of enhanced services • Permits end-to-end testing before FITS is shipped to the field • Eliminates costly field inventory holding costs • Promotes increases in field installation productivity • Minimizes network installation expense • High quality factory termination maximizes network performance • Reliability lowers system maintenance cost over time • Full factory warranty against manufacturing defects • Meets or exceeds stringent Telcordia testing standards
For splicing up to four fiber drop cable to a fiber distribution cable
Allows for testing entire system before it goes to the field
Designed to work with central core tube cable and stranded fiber
Significantly reduces the cost of deploying fiber in the local loop
Meets same environmental/mechanical performance specifications as XAGA 1650 closures (filled splice closure based on heat-shrink technology)
The Factory Installed Fiber-Optic Termination System (FITS FOSC) is a taut-sheath, in-line closure for "pre-terminated plant" where all fiber splicing and closure installations are done in a controlled factory environment. Installed closures can be shipped to the field on 30-inch reels and pulled through two-inch bores with up to 600 pounds of force. Closure sealing and cable strain relief are achieved by heat shrinking an outer body or sheath. During the installation, a cable core blocking system capable of withstanding a 20-foot waterhead for 30 days seals to protect the termination.
