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.

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.

Thepowersupplymodules(PSMAC)acceptvoltagesfrom100‐240VAC,50/60Hz.Maximumpowerconsumptionis100Wpermodule.
Althoughthepowersupplymodulesaredesignedtobehotswappable,itisoptimalpracticetoinsertamoduleintothechassispriortothe
applicationofACpower.Thepowersuppliesmustbeinstalledinthetopmostslotwhenviewingtheinsertionendof
therespectivemodelchassis.Asecondaryredundantpowersupplymaybeinstalledinthebottomslot.
Toaccessthefuses,disconnectpowercord,andremovethepowersupplyunitfromthechassis.Replacementfusesmusthavetherequired
currentratingandmustbeofthespecifiedtype.Useofrepairedfusesand/orbypassofthefuseholdersisnotrecommendedandwillvoid
thewarranty.
Thesystempowerrequirementfora17‐unit(maximum)rackconfigurationis115VAC@15Amps;ifsuppliedwith230VAC,8Ampsis

UsingRedundantPowerSupplies
TheWDM16/8unitscomestandardwithasinglePSMACpowersupplyinstalled.Thisconfigurationmaybeperfectlyacceptableformany
applications.Inthecaseofmissioncriticalapplicationswhichhavezerotolerancefordowntime,itisadvisabletoaddasecondoptional
PSMACpowersupplyforcompleteredundancy.Thesecondsupplycanbeinsertedatanytimeintheunusedpowersupplyslot.Insertthe
supplyfirst,thenapplyexternalACpower.
ThePSMACandtheWDM16/8support‘hotswapping’ofthepowersupplies.Thismeansthateithersupplycanberemovedorinserted
withoutpoweringdowntheunit.Withtwosuppliesinstalled,intheeventofafailureofonePSMAC,theunitwillcontinuetooperateonthe
remainingsupply.Anewreplacementcanbeinstalledandpoweredupwithoutdisturbingtheunit.
Bestpracticeforutilizingredundantpoweristoconnecteachsupplytoadifferentpowersourceor‘phase’ofpower.Thiswayifonephase
ofpowersuffersanoutage,theunitwillcontinuetoworkontheremainingphase.
PowerSupplyModuleFuseReplacement
Thepowersupplymodulesareeachprotectedbyasingle2Atime‐delayfuse(Littlefusemodel218.002Slo‐Blo).Replacementofthefuse
requiresthepowercordtobedisconnectedfromthepowersupplyACinletandthepowersupplytoberemovedfromthechassis.Toaccess
thefuse,useanappropriatesizedflatheadscrewdriverandremovetheFuseCompartmentCap.ThefusewillsimplyslideoutoftheFuse
Compartmentwiththecapremoved.SlideanewfusewhichmeetsthestatedspecificationsintotheFuseCompartmentandreplacethecap.
Youmaynowre‐insertthepowersupplyintothechassisandreconnectthepowercordtothepowersupplyACinletconnector.
Replaceonlywithidenticalorequivalenttime‐delayfuse.

HandlingWarnings
SFPModulesarestaticsensitive.Topreventdamagefromelectrostaticdischarge(ESD),itisrecommendedtoattachanESD
preventativewriststraptoyourwristandtoabaremetalsurfacewhenyouinstallorremoveanSFPModule.
DisconnectallopticalorcoppercablesfromSFPModulespriortoinstallingorremovingtheSFPModule.Failuretodosocould
resultindamagetothecable,cableconnectorortheSFPModuleitself.RemovingandinsertinganSFPModulecanshortenits
usefullife,soyoushouldnotremoveandinsertSFPModulesanymoreoftenthanisabsolutelynecessary.
ProtectopticalSFPmodulesbyinsertingcleandustcoversintothemafterthecablesareremoved.Besuretocleantheoptic
surfacesofthefibercablesbeforeyouplugthembackintotheopticalportsofanotherSFPmodule.Avoidgettingdustandother

ConnectingAggregateFiberConnection
ANeutrik™opticalCONDUOconnectorprovidesabi‐directionalsinglemodefiberinterfacetotheaggregatedI/OoftheCWDM.Thisoptical
signalcarriesthedatausingall16(8)wavelengthsinternallyallocatedtothe16(8)externalSFPcages.Duetoitsbroadwavelengthcontent,
thisopticalsignalisnotcompatiblewithsinglewavelengthpassiveoractiveopticaldevicessuchaspassivesplitter,opticaltransceiver

withLCterminations.
MakingaTacticalConnection
AtacticalfiberconnectioncanbeachievedbysimplyutilizingaNeutrik™opticalCONDUOfibercableassemblyfortheaggregatefiberrun.
TheopticalCONcableconnectorwillsimply‘push’intoplace.Disconnectingthecablerequiresgraspingthecableconnectorwithyourfull

VideoOptimization
TheSocietyofMotionPictureandTelevisionEngineers,orSMPTE,isaleaderinthedevelopmentofstandardsforfilm,television,andother
video.TheSerialDigitalInterfaceorSDI,wasstandardizedbySMPTEforbroadcastqualitydigitalvideotransmission.Otherstandards
evolvedfromthisoriginalstandard,definingEnhanced,High‐definition(HD),3G‐SDI(1080p)andUltraHigh‐definition(UHD),or4Kvideo
(2160p).
Tohelpensureerror‐freetransmission,thestandardsincludeadatascrambler/descramblertocreateahighdensityoftransitionsinthe
serialdata,makingiteasierforthereceivertomaintaintiming.Whereanencodingmethodsuchas8B‐10Bensuresaminimalsequentialrun
ofallonesorzeros,itdoessoatthecostofa25%increaseinbandwidthrequirements.Thescrambler/descramblermethoddoesnot
requirethis,butasaresulttherearecertaincombinationsofscramblerstateandthenextdatabitstobescrambledthatresultinasequence
ofuptotwentyconsecutiveonesorzeros.Thesesequencesarereferredtoaspathologicalconditions,andarepresentinspecificshadesof
pinkorgrey.
ThesepathologicalconditionsmaycreateerrorsintransmissionthroughtypicalACcoupledoptics,oranyotherACcoupledinterface.Video
EnhancedorSMPTECompliantopticsaredesignedtoacceptthesepathologicalconditions,allowingthelongersequencesofonesorzerosto
passwithouterror.
TheFiberplexTechnologiesWDM16andWDM8ActiveCoarseWaveDivisionMultiplexerhasVideoEnhancedopticspre‐installedinternally
oneveryport,ensuringerror‐freetransmissionforallofyourvideorequirements.
SFPMSACompliance
TheSFPMulti‐SourceAgreement(MSA)isanagreementthatwasdraftedamongcompetingmanufacturersofSFPopticalmodules.TheSFF
CommitteewasformedtooverseethecreationandmaintenanceoftheseagreementsincludingtheSFPMSAdesignatedasINF‐8074i.This
agreementdescribesamutuallyagreeduponstandardfortheformandfunctionofSFPmodules.However,notallSFPsproducedareMSA
compliant.TheMSAprovidesforatransceiver(TX/RX)pinout.OtherindustriessuchasbroadcasthadtheneedfordualTXanddualRXSFP
foruni‐directionalapplicationssuchasvideo.Naturally,anon‐MSAstandardwasintroducedallocatingpinoutassignmentsfordualoutput
anddualinputI/Oconfigurations.Inaddition,thesomeoftheinternalserialcommunicationpinswerereassigned.
TheuniquedesignoftheWDM16/8includesinternalmulti‐rate,CWDMopticalSFPswhichhandlethewavelengthallocationoftheCWDM.
TheseinternalmodulesareMSAcompliant,thustheexternaluseraccessibleSFPmodulesmustalsobeMSAcompatible.Forthisreasonyou
cannotusenon‐MSASFPswiththeWDM16/8.
BesurethatanySFPsthatyouwishtousewiththisunitconformtothepinoutinFigure9.
