OVERVIEW
Differ from past residential telecommunicationsinfrastructure such as the telephone and thecable TV networks. Those networks were builtto support specific applications - telephone
service and cable television. Fiber is already well entrenched as the medium
of choice for intercontinental and intercitycommunication.
the current battle for an optimum solution Isthe promise and the methodology of extendingfiber onward to the userspremises.

FTTH networks
fiber to the home (FTTH), it means to include alsofiber to the users premises (FTTP) and fiber to thebusiness (FTTB)any situation where the optical pathin the fiber runs all the way to individual end-user
premises. FTTH is designed to be a full-service networking
platform that supports a variety of communicationsand information services, including voice, video, andInternet access.
FTTH is intended to be a flexible communicationsinfrastructure that supports present as well as futureservices.

The Advantages of FTTH
For customers: FTTH is the only technology that will deliver enough
bandwidth, reliably and at a low enough cost.
Integrated voice, data, and video transmutation

The Advantages of FTTH
For providers:
Ability to offer integrated services could mean higher profits
No electronics in the field means less maintenance
Costs of implementing technology are dropping - are similar to
costs of deploying copper but payoff is much larger

TheLimitationsofFTTH
For customers: Not widely available yet
Monthly and installation costs may be prohibitive
Needs battery back-up in case power goes out
For providers: Uncertainty over willingness of residential customers to pay
for it since most people don't need that much bandwidth
capacity .
Easier to deploy in new neighborhoods rather than existingones because of cost and inconvenience of laying cable
(using sewer or electric lines may allow providers to
overcome this obstacle).

How fast is FTTH?
Can be greater than 2.5 G bps
Residential/business FTTH typically offers speeds
from 10 mbps to over 100 mbps
Are there distance limitations?
Using PON, providers install splitters up to 30,000feet from a central office. Splitters send the signalanother 3000 feet to customers' homes orbusinesses.

FTTH and FTTB NetworkArchitectures
optical networks has two major branches, PON and AON PONstands for passiveoptical network.It refers to the
fact that there are no active electrical devices between thecentral office and the end user. All the handling of thelight beams that carry the signal are done with mirrors,
prisms and fiber. There are no electrical devices needed.

FTTH and FTTB NetworkArchitectures
AON stands for active optical network. there areelectrical devices between the user and the centraloffice. These devices are routers and switches, almostalways using the Ethernet standard.

Conclusion:
the regulators will have to understand and deal withthe fact that such stupendous last-mile capacity inthe hands of the first provider to deploy FTTH willgive that provider such a head start that some new
thinking about monopoly power in this setting willbe absolutely Required.
It is not at all clear today whether, as time passesand the insatiable human greed for more and
cheaper bandwidth persists, the entire pathbetween subscribers will become all-optical.
