Multimodefibersare used forLAN applicationsonly,while singlemodefibers areused forall telecom applications,offering

almost unlimited bandwidth.Therefractive indexn must beknownfor OTDRmeasurements,sinceit directlyaffectsthe accuracy

offault location.Typicalvalues aregiven above.1

Fiberoptic transmissionmakesuse ofthe threeopticalwindows (850,1300,1550 nm) that aregiven bythe attenuationcharacteristics

ofthe silica fibers.Also,670 nm light isused forvisible fault location,and low-cost 780 nm lasershavebeen introduced forshort haul

accessnetworks.For on-linetest purposes(fibermonitoring),1625 nm isused tocover evenlong haulapplications.
