Module Optical waa qalabka hardware ee muhiimka ah si loo xaqiijiyo isku xirka shabakada indhaha ee xarunta xogta. Kordhinta tirada dekedda iyo cufnaanta, kharashka moduleka indhaha ayaa ku xisaabtami doona ku dhawaad kala badh kharashka shabakada indhaha ee xarunta xogta. Waqtigan xaadirka ah, tiknoolajiyada isku xirka 100G ayaa si weyn loogu isticmaalay xarumaha xogta cusub ee shirkadaha waaweyn ee internetka, iyo 400G tignoolajiyada isku xirka ayaa si ballaaran loo isticmaali doonaa sanadaha 1-2 ee soo socda. Sidaa darteed, tignoolajiyada hirgelinta ee 400G module indhaha ayaa noqday diiradda warshadaha.
Marka la eego dhererka hirarka iftiinka, moduleka iftiinka 400G waxaa loo qaybin karaa qaabab badan (MM) iyo hal-mode (SM) hadda) .Marka la eego fogaanta gudbinta, 400G moduleka indhaha waxaa loo qaybin karaa SR, DR, FR iyo LR. Laga soo bilaabo foomka baakooyinka, 400G moduleka indhaha waxa loo qaybin karaa CDFP, CFP8, OSFP, qsfp-dd iyo wixii la mid ah. Hoos waxaa ku yaal kala-soocidda farsamada ee moduleka indhaha ee 400G.
Module-kii hore ee 400G wuxuu adeegsaday 16-kanaal 25Gbps NRZ hirgelinta (sida 400g-sr16), iyadoo la adeegsanayo CDFP ama xirmada CFP8. Faa'iidada NRZ waa in laga amaahan karo tikniyoolajiyadda 25G NRZ ee baaluq ee 100G module indhaha, laakiin khasaaradu waa inay u baahan tahay 16 kanaal oo calaamad u ah gudbinta isbarbardhigga ah, oo leh isticmaalka awood iyo mugga xad dhaafka ah, taas oo aan ku habboonayn codsiga xarunta xogta.
Qeybta hadda jirta ee 400G, 8-kanaalka 53GbpsPAM4 (400g-sr8,FR8,LR8) ama 4-channel 106GbpsPAM4 (400g-dr4, FR4, LR4) ayaa inta badan loo isticmaalaa si loo gaaro gudbinta 400G ee dhinaca dekedda indhaha, iyo 8. -channel 53GbpsPAM4 signalka korantada waxaa loo isticmaalaa dhinaca dekada korantada, iyada oo la qaadanayo qaabka baakadaha OSFP ama qsfp-dd. Labada baakadood ee OSFP iyo QSFP-DD waxay bixiyaan 8 - kanaalka isdhaafsiga calaamadaha korantada.Marka la barbardhigo, cabbirka qsfp-dd waa ka yar yahay (oo la mid ah xirmada 100G ee caadiga ah ee QSFP28 xirmada), taas oo ku habboon codsiyada xarunta xogta. Cabbirka xirmada OSFP xoogaa way ka weyn tahay, sababtoo ah waxay bixin kartaa isticmaalka koronto badan, si aad ugu habboon codsiyada isgaarsiinta.
Jaantuska soo socdaa wuxuu muujinayaa hirgelinta 400g-fr8 /LR8 iyo 400g-fr4 siday u kala horreeyaan.
(Tixraac：Faahfaahinta OSFPMSA ee OSFP OCTAL FACTOR PLUGGABLE MODULE.)Waxaa la arki karaa in dhinaca interface-ku yahay 8-channel 53Gbps PAM4. Loogu talagalay 400g-sr8 / FR8/LR8 iyo qaybo kale,
CDR (dib u soo celinta saacada) iyo koronto/optical ama beddelka korantada ayaa kaliya lagu sameeyaa gudaha moduleka indhaha. Sidaa darteed, dhinaca dekedda indhaha ayaa sidoo kale ah 8-channel 53Gbps PAM4, sida cabbirka dekedda korontada. Wixii 400g-dr4 / FR4 / LR4 iyo modules kale, waxaa jira chips Gearbox gudaha moduleka indhaha oo dhufanaya talooyinka labada. dekedaha galay hal signal oo u beddelo iftiinka, sidaas darteed xawaaraha dhinaca dekedda indhaha laba jeer ka badan yahay dhinaca dekedda, kuwaas oo, 106GbpsPAM4 signal.
