theunit,itmustnotbeconnectedtotheACpoweroutlet,oritmustbeimmediatelydisconnectedbyunpluggingthepowercable.Repair

mustonlybeperformedbytrainedpersonnelinaccordancewiththeapplicableregulations.

InstallationSite

Installtheunitinaplacewherethefollowingconditionsaremet:

Thetemperatureandtherelativehumidityoftheoperatingenvironmentmustbewithinthespecifiedlimitsduringoperationof

theunit.Valuesspecifiedareapplicabletotheairinletsoftheunit.

Condensationmaynotbepresentduringoperation.Iftheunitisinstalledinalocationsubjecttolargevariationsofambient

temperature(e.g.inanOB‐van),appropriateprecautionsmustbetaken.

Unobstructedairflowisessentialforproperoperation.Ventilationopeningsoftheunitareafunctionalpartofthedesignandmust

notbeobstructedinanywayduringoperation(e.g.‐byobjectsplaceduponthem,placementoftheunitonasoftsurface,or

improperinstallationoftheunitwithinarackorpieceoffurniture).

Theunitmustnotbeundulyexposedtoexternalheatsources(directsunlight,spotlights).

AmbientTemperature

UnitsandsystemsbyFiberPlexaregenerallydesignedforanambienttemperaturerange(i.e.temperatureoftheincomingair)of5°Cto40

°C(41°Fto104°F).Whenrackmountingtheunits,thefollowingfactsmustbeconsidered:

Thepermissibleambienttemperaturerangeforoperationofthesemiconductorcomponentsis0°Cto+70°C(32°Fto158°F)

(commercialtemperaturerangeforoperation).

Theairflowthroughtheinstallationmustallowexhaustairtoremaincoolerthan70°C(158°F)atalltimes.

Averagetemperatureincreaseofthecoolingairshallbeabout20°C(68°F),allowingforanadditionalmaximum10°Cincreaseat

thehottestcomponents.

Inordertodissipate1kWwiththispermissibleaveragetemperatureincrease,anairflowof2.65m³/minisrequired.

Example:ArackdissipatingP=800Wrequiresanairflowof0.8*2.65m³/minwhichcorrespondsto2.12m³/min.

Ifthecoolingfunctionoftheinstallationmustbemonitored(e.g.forfanfailureorilluminationwithspotlamps),theexhaustair

temperaturemustbemeasureddirectlyabovethemodulesatseveralplaceswithintheenclosure.

GroundingandPowerSupply

Groundingofunitswithmainssupply(ClassIequipment)isperformedviatheprotectiveearth(PE)conductorintegratedinthree‐pin

Phoenix™connector.Unitswithbatteryoperation(<60V,ClassIIIequipment)mustbeearthedseparately.Groundingtheunitisoneofthe

measuresforprotectionagainstelectricalshockhazard(dangerousbodycurrents).Hazardousvoltagemaynotonlybecausedbydefective

powersupplyinsulation,butmayalsobeintroducedbytheconnectedaudioorcontrolcables.

Thisequipmentmayrequiretheuseofadifferentlinecord,attachmentplug,orboth,dependingontheavailablepowersourceat

installation.Iftheattachmentplugneedstobechanged,referservicingtoqualifiedpersonnel.



Introduction

TheFiberPlexWDMisan8or16ChannelWavelengthDivisionMultiplexer,witheachopticalchannelbroughtouttoanSFPslot,sotheuser

doesnotneedtosupplywavelength‐specificmodules.EachchannelcanbelinkedviafiberwithselectedFiberPlexFOMorFOIfibermodules,

FiberPlexLightViper™orwithvirtuallyanythirdpartyfiberopticequipmentwithdataratesfrom155megabitsupto3gigabitsperchannel,

forapossiblemaximumaggregatedatarateof48gigabits.

TheuserdataentersandleavestheWDMvia16SFPslotsontheWDM16,or8slotsontheWDM8AandWDM8B,whichcanbeleft

unpopulatedforunusedchannels,orpopulatedwithuser‐suppliedMSA‐compliantSFPmodulesthatareappropriatefortheuser’sdatarate,

protocolandjitterrequirements.Internally,theseconnecttofiberoptictransceiverswhicharetunedtothespecificwavelengthsforthe

channels,whicharethenmultiplexedontotheaggregatepairwhichconnecttotheotherWDM(s)inthelink.Datathatentersaspecific

channelononeWDMwillappearonthecorrespondingchannelontheotherWDM(s)inthelink,withnointerferencewithanyother

channels.

Possiblelinkconfigurationsare:

WDM16toWDM16–all16channelsthrough

WDM8AtoWDM8A–all8channelsthrough

WDM8BtoWDM8B–all8channelsthrough

TheaggregatefibersfromtheWDMunitsexitthechassisviaaduplexLCcoupler,whichconnecttosinglemodefiber,upto20kminlength.

Sincethisisanaggregatedwidebandstream,anyuserequipmentintheopticalpath(switches,couplers,etc.)mustbeabletoaccommodate

theentirebandwidthwithoutattenuation,andwillnotbeabletoreceiveordecodethestreamdigitally.

TheWDMunitshaveprovisionfortwo(2)powersupplymodulesforredundancyeachhavingcapacitytopowertheentireunit.AnACpower

inputmoduleisavailablenowandaDCversionisindevelopment;bothare‘hotswappable’.

KeyFeatures

16(or8)ChannelActiveWaveDivisionMultiplexer

Combines16(or8)opticalchannelsintoasinglefiberpair

Eachchannelindependentlysupportsdataratesfrom155MBupto3GB

SMPTEcompatibleinternalfiberoptics,videooptimizedtosupportPathologicalSignals

Eachopticchannelcanindependentlyacceptmultimodeorsinglemodeoptics,coaxconnectionorCAT5usingflexibleSFPmodules

Fullyredundant,hotswappablepowerforultimatereliability



WDMTheoryofOperation

Infraredlighthasafrequencyofapproximately400Terahertz(400,000Gigahertz).Thatisabout125,000timeshigherthanthedatarateofa

typical3GigabitSFP,whichmeansalargeproportionofthebandwidthofafiberopticcableiswasted.Thecurrentstateoftheartdoesnot

allowutilizingallofthatbandwidth,butwecanrecoversomeofitbyatechniquecalled“CoarseWaveDivisionMultiplexing,”or“CWDM.”

Essentially,itisthesimpletechniqueoftakingeach3Gigabitchannelandusingittomodulateadifferentfrequencyinthat400Terahertz

bandwidth.Thisisdonethroughaseriesofopticalfiltersandcombiners,alongwithlasersandphotodiodestunedtoaparticularinfrared

centerfrequency.Historically,however,opticsarereferredto,notbytheirfrequency,butbytheirwavelength,whichisthespeedoflight

dividedbythefrequency.

InthetraditionalimplementationofaCWDM,itistheuser’sresponsibilitytoprovidethetailoredSFPsandtheCWDMitself,whichmay

requireadapterstointerfacewiththeuserequipment.

TheFiberplexWDMline,ontheotherhand,isanactiveWDM,withthewavelength‐specificcomponentsalreadytestedandconfigured.

Insteadofawavelength‐specificopticalfiber,agenericSFPelectricalinterfaceisprovidedforeachchannel.AnySFPthatconformstothe

MSAcanbeinserted,evencopper‐basedSFPslikegigabitEthernet,SDI,HDMIorMADI.

TheinternalSFPshaveafull3Gigabitbandwidth,video‐optimized.GenericfiberSFPshavelimitationsinpassingvideosignals,sincetheydo

notmaintainaconstantDClevel.Thevideo‐optimizedSFPsareconstructedtobetterhandletheshiftingDClevelsinvideosignals.



PowerRedundancy

Inordertoremainfunctional,evenintheeventofcomponentfailures,theWDMemploysthefollowingredundancies:

Twopowersupplyslots,withloadequalizingandprotectioncircuitryonthebackplane.Eachsupplyhasthermalandovercurrent

protection.

Eachchannelhasitsownindependentpowersupplythatrunsoffofthemainpowerrails,sothatafailureinonechannelwillleave

theothersoperational.

Thereisamicroprocessorintheunit,butitsfunctionispurelymonitoring.Ifitfails,thedatawillcontinuetoflowunimpededonall

opticalchannels.

Therearetwoindependentfancontrolchannels,andtwocoolingfansoneachsideoftheunit.

DifferencesbetweenWDM16,WDM8AandWDM8B

ThefunctionalandphysicalcharacteristicsoftheWDM16,WDM8AandWDM8Barelargelyidentical.Thesingledifferentiatoristhenumber

ofActiveWaveDivisionchannelsandtheassociatedinternalwavelengthsthataresupported.Thechassisdimensionsandpowersupplies

remainidentical.

TheWDM16supportsallofthe16standardCWDMwavelengthsof1310‐1610nm,whereastheWDM8unitssupportonly8ofthose

channels,sotheinstallationcanbescaledtotheappropriatesize.TheWDM8Asupportstheupper8wavelengths1470‐1610nmandthe

WDM8Bsupportsthelower8wavelengths1310‐1450nm.BecauseoftheenormouslyflexibleactivenatureoftheWDM16/8,the

wavelengthsoftheinternalchannelsarebasicallyinvisibleandevenirrelevanttotheenduser.Thereasonstherearetwosubsetsof

wavelengthssupportedthroughtheWDM8AandWDM8Bisforfutureexpandabilityofthelineinprovidingthepossibilityofadd/drop,

combiningandsplittingcapability.

Whenonly8channelpointtopointfunctionalityisdesired,theWDM8Ashouldbethemodelofchoice.

GettingStarted

InitialInspection

Immediatelyuponreceipt,inspecttheshippingcontainerfordamage.Thecontainershouldberetaineduntiltheshipmenthasbeenchecked

forcompletenessandtheequipmenthasbeencheckedmechanicallyandelectrically.Iftheshipmentisincomplete,ifthereismechanical

damage,oriftheunitfailstooperatenotifyFiberPlexandmaketheshippingmaterialsavailableforthecarrier'sinspection.

ChassisMounting

Mountthechassisusingfastenersappropriatetoyourstandard19”rackenclosure.Allfour(4)mountingpointsMUSTbeutilized.Ensure

thatthereexistsadequateclearanceforfrontandrearventilation.Thechassisshouldbelocatedinanenvironmentwhereanambient

temperaturebetween0°and50°Ccanbemaintained.
