INTRODUCTION Tremendous expansion in the global
telecommunication network had led to the
tremendous explosion in bandwidth demandand requirement
For the user to acess and utilize broad servicesavailaiblethrough developments designers must
provide a flexible and cost effective solution forthe last mile.
Focuses on FSO as an enabling technology thatwould help serve growing bandwidth
requirement

Last-mile technology is any telecommunications
technology that carries signals from the broad
telecommunication backbone along the relatively
short distance (hence, the "last mile") to and fromthe home or business.

FSO is an optical technology that allows transmission of
video, voice, and data through the air using lasers or
LEDs (light emitting diodes). Instead of the pulses of light
being contained within a glass fiber, they are transmitted
in a narrow beam through the atmosphere.

ECONOMICDRIVERS
FSO systems require less than one-fifth of thecapital expenditure of comparable ground-basedfiber-optic technologies
Revenue Generation for Service Providers:FSOsystems would include new SLA (service level
agreements),QoS (quality of service)enhancements,dedicated wavelengths

FSO APLICATIONS
Telecommunication Network Extensions:FSOcan be deployed to extend an existing areanetwork.
Enterprise: The flexibility of FSO allows it to bedeployed in many enterprise applications such
as LAN-to-LAN connectivity. Last-Mile Connectivity:These links can be
configured as PTP (point-to-point), PMP (point-to-multipoint),ring, or mesh connections, for the
last mile.

OPTSIM
OptSim is an intuitive modeling and simulationenvironment supporting the performance evaluation anddesign of the transmission level of optical
communication systems.HIGHLIGHTS OF THE SOFTWARE:
Performance analysis and wide choice of measurements
Top simulation accuracy and speed due to the split-step
method and the algorithm optimization High flexibility for component specification
Fast learning curve and usability

THE BECHTEL FSO INITIATIVE
Bechtel Telecommunications, Frederick,Maryland, has commissioned an FSO system,which has been operational since March 2002.The FSO equipment being used is fSONA.
The availability, as advertised by the
manufacturer, can be up to 99.999 percent atappropriate link ranges for given weatherconditions.

CONCLUSION
Optical wireless is a mature and reliableapproach for broadband access. There has been
tremendous increase in high-bandwidthapplications at the edge of the network.However, this is only possible with highspeed
connectivity between the edge and the core ofthe network. FSO systems offer a viable solutiontoward building optical connectivity in a cost-effective, quick, and reliable manner.
