Attenuation

What is itAttenuationindicatesthepowerlossofalightpulsegoingthroughanopticalfibrehavingacertainlength.Thesignalreduction,duetodispersionandabsorptionphenomena,hasanexponentialdecaybasedonthefibrelength.Theratiobetweentheoutletpowerandtheinletpower,expressedinalogarithmicfunction,representsaquantitylinearlydependingonthefibrelength.SuchaquantityisexpressedindB/Km.Thisisdefinedasintrinsicattenuationdependingonthetypeoffibreandonitslength.However,ifafibreissubjecttosidepressure(microbending)ortonarrowbendingradius(macrobending),theattenuationcanundergoevendrasticincrements.Attenuationisthemostimportantparametertobekeptundercontrolwhilemanufacturingandlayingopticalcables.Thecablemanufacturermustguarantee,duringthosephases,theprescribedattenuationlevels.

DispersionWhat is itTherearetwotypesofdispersion:chromaticdispersionandmodaldispersion.Bothhaveanimpactonthebandwidthlimitation(quantityoftransmittabledata)andareexpressedinps/(nm.km).

■■ Chromatic dispersion, is the phenomenon causing a light pulse in a fibre to run at a speed that depends on its wavelength. Since perfectly monochromatic pulses do not exist in reality (even laser ones), the various pulse components, inside the fibre, run with their own speed and consequently, the pulse at the outlet is wider than the original one (the components close to the infrared slow down, the ones close to the ultraviolet accelerate). When two pulses, close to each other, interfere till they become indistinguishable, then you have a band limitation. See picture below. This phenomenon exists both for singlemode and for multimode fibres.

■■ Modal dispersion, is only referred to MM fibres and is due to the differences in the transit time of the various modes in which the original pulse is decomposed. Since each mode covers optical paths with different lengths (and therefore with different times), the consequence is always the widening of the pulse and the consequent risk of band overlapping or limitation.

How to measure itMainmeasuringmethodsareessentiallythree:MPS(modulationphase-shift),DPS(differentialphase-shift)and PULSE-DELAY.Thefirsttwomethodsrequiretoaccessthetwoconnectingheadsandtheuseofcomplexinstrumentation;asaconsequence,theuseonthefieldisnotreallyfeasible.Thethirdmethod,onthecontrary,onlyrequirestoaccessonemeasuringheadandusescompactinstrumentation.

MPS,calculatesthegrouppulsedelaybymeasuringthephasedisplacementthatisformedbetweenamodulatedpulsethatgoesthroughthesectionfibreandtheoriginalmodulatedpulse.Theapparatusismainlyformed(seepicture)byamodulatedlasersourceandavectorialRFnetworkanalyzer.

■■ The MPS method measures the phase difference between a transmitted and received signal. The RF network analyzer modulates the amplitude of the laser’s signal.

DPS,isverysimilartothepreviousone,exceptforthefactthat,beingequippedwithawavelengthselector(seepicture),itispossibletoselectverytightwindowswithinthelaseremissionspectrum.Inthisway,itispossibletodirectlymeasurethechromaticdispersiononthebasisofthewavelength.

■■ Like the MPS method, the DPS method also modulates the amplitude of the laser’s signal. But the DPS method also slightly varies, or dithers, the laser’s wavelength.

Fibre Optic Cables

We have tried, with this catalogue,

to show you our experience,

our way of thinking and operating

in the creation of fibre optic cables.

We believe the cables you have seen here

are good practical examples.

When it comes to your own cable

we can co-design it together:

you let us know your specific situation

and we will create your cable all around it.

Cavicel can create it for you.

Thank you for calling Cavicel.
