FIBER TO THE HOME (FTTH)


2/13

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


5/13

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


6/13

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).

FTTH Versus Other Types of FiberNetworks

Fiber-to-the-Home (FTTH)

Fiber-to-the-Building (FTTB)

Fiber-to-the-Node (FTTN)

Fiber-to-the-Curb (FTTC)

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.


10/13

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.
