Hordhaca aasaasiga ah ee moduleka indhaha
Module-ka indhaha waxa uu ka kooban yahay aaladaha optoelectronic, wareegyada shaqada iyo is-dhexgalka indhaha. Aaladaha optoelectronic waxay ka kooban yihiin laba qaybood: gudbinta iyo helitaanka. Marka la soo koobo, shaqada moduleka indhaha ayaa ah in loo beddelo calaamadda korantada ee calaamadda indhaha ee dhamaadka dirida. Ka dib marka isha isha lagu kala qaado iyada oo loo marayo fiber optic, dhamaadka helaya wuxuu u beddelaa signalka indhaha signalka korantada.
Qaybta gudbintu waa: gelinta signalka korantada ee xoogaa xoogaa xoogaa ah waxaa farsameeyaa chip-ka wadaha gudaha, ka dibna wuxuu wadaa laser-ka semiconductor-ka (LD) ama diode-ka iftiinka iftiinka (LED) si uu u sii daayo calaamadda indhaha ee la beddelay ee heerka u dhigma. Xakamaynta kontoroolka tooska ah ee korantada gudaha waxay u qalabaysan tahay si ay u ilaaliso tamarta ishaarada indhaha ee wax soo saarka.
Qaybta helaysa waa: Module gelinta signalka indhaha oo leh xoogaa xoogaa xoogaa ah waxa loo beddelaa signalka korantada ee diode-ka ogaanshaha indhaha, iyo signalka korantada oo leh heerka xoogaa yara ee u dhigma waxa uu soo baxayaa ka dib preamplifier-ga.
-Fikradda aasaasiga ah ee moduleka indhaha-
Port-optical module waa magaca guud ee qaybaha kala duwan ee moduleka, guud ahaan tixraacaya moduleka isku dhafan ee transceiver indhaha
-Shaqada moduleka indhaha-
Shaqadeedu waa si fudud in la xaqiijiyo beddelka u dhexeeya calaamadaha indhaha iyo calaamadaha korantada.
-qaab-dhismeedka module indhaha-
Module-ka indhaha waxa uu inta badan ka kooban yahay gudbiyaha indhaha, qaataha indhaha, wareegga shaqada iyo indhaha (korontada).
Gudbiyaha, jilibka darawalku waxa uu farsameeyaa calaamada korantada ee asalka ah, ka dibna waxa uu wadaa laysarka semiconductor (LD) ama diode iftiimiya (LED) si uu u sii daayo signalka indhaha ee habaysan.
Dekeddu waxay ku taallaa dhammaadka soo dhawaynta. Ka dib markii calaamadda indhaha soo gasho, waxa loo beddelaa signalka korantada by diode ogaanshaha indhaha, ka dibna soo saari signal koronto iyada oo loo marayo preamplifier.
-Qoritaanka qaabka indhaha-
-Taariikhda horumarinta qaabka indhaha-
-Hordhaca baakadaha moduleka indhaha-
Waxaa jira heerar baakad ballaaran oo kala duwan oo loogu talagalay modules-yada indhaha, badi sababtoo ah:
》Xawaaraha horumarinta tignoolajiyada isgaarsiinta fiber optic-ga waa mid aad u degdeg badan. Xawaaraha moduleka indhaha ayaa sii kordhaya, mugga ayaa sidoo kale hoos u dhacaya, si dhowrkii sano ee kasta, calaamado cusub oo baakad ah ayaa la soo saari doonaa.
sax Sidoo kale way adag tahay in la waafajiyo heerarka baakadaha cusub iyo kuwii hore.
》Scenarios codsiga ee modules indhaha waa kala duwan yihiin. Masaafada kala duwan ee gudbinta, shuruudaha bandwidth, iyo meelaha la isticmaalo, oo u dhiganta noocyada kala duwan ee fiber indhaha la isticmaalo, modules indhaha ayaa sidoo kale ka duwan.
Dekedda GBIC
GBIC waa Giga Bitrate Interface Converter.
Kahor 2000, GBIC waxay ahayd baakadaha moduleka indhaha ee ugu caansan iyo qaabka moduleka gigabit-ka ugu isticmaalka badan.
Dekedda SFP
Sababtoo ah cabbirka weyn ee GBIC, SFP ayaa soo muuqatay mar dambe oo waxay bilowday inay beddesho GBIC.
SFP, magaca buuxa ee Foomka-Foom-factor Pluggable yar, waa unug yar oo kulul oo la isku beddeli karo. Xajmiga yar waxa uu la mid yahay baakadaha GBIC. Baaxadda SFP waa nus ka yar kan moduleka GBIC, in ka badan laba jeer tirada dekedaha waxaa lagu habeyn karaa isla guddi isku mid ah. Marka la eego shaqada, waxaa jira farqi yar oo u dhexeeya labada, oo labaduba waxay taageeraan xidhidh kulul. Xaddiga ugu badan ee ay taageerto SFP waa 4Gbps
XFP afka
XFP waa 10-Gigabit Small Form-factor Pluggable, kaas oo la fahmi karo marka la eego. Waa 10-Gigabit SFP.
XFP waxay qabataa modul taxane ah oo hal kanaal ah oo xawli buuxa leh oo ku xiran XFI (10Gb serial interface), kaas oo bedeli kara Xenpak iyo asalkiisa.
Dekedda SFP+
SFP+, sida XFP, waa moduleka indhaha ee 10G.
Baaxadda SFP+ waxay la mid tahay ta SFP. Way ka cufan tahay XFP (waxaa la dhimay ilaa 30%), isticmaalkeeda korontaduna sidoo kale wuu ka yar yahay (waxaa yareeyay qaar ka mid ah hawlaha xakamaynta calaamadaha).
O SFP28
SFP oo leh 25Gbps ayaa inta badan sababta oo ah 40G iyo 100G modules-yada indhaha aad bay qaali u ahaayeen wakhtigaas, markaa qorshahan kala guurka ah ayaa la sameeyay.
QSFP/QSFP+/QSFP28/QSFP28-DD
Quad Small Form-Factor Pluggable, afar-kanaal SFP interface. Farsamo badan oo muhim ah oo ku jira XFP ayaa lagu dabaqay naqshaddan. QSFP waxaa loo qaybin karaa 4 iyadoo loo eegayo xawaaraha × 10G QSFP+, 4 × 25G QSFP28, 8 × 25G QSFP28-DD module indhaha, iwm.
Qaado QSFP28 tusaale ahaan, taas oo khuseysa 4 × 25GE marin u helka. QSFP28 waxaa loo isticmaali karaa in laga cusboonaysiiyo 25G loona gudbiyo 100G la'aanteed 40G, taas oo si weyn u fududaynaysa dhibka fiilooyinka iyo dhimista kharashyada.
QSFP/QSFP+/QSFP28/QSFP28-DD
QSFP-DD, oo la aasaasay bishii Maarj 2016, waxaa loola jeedaa "Laba Cufnaanta". Ku dar safka kanaalada 4-ta kanaal ee QSFP oo u beddel 8 kanaal.
Waxay la jaan qaadi kartaa nidaamka QSFP. Qaybta asalka ah ee QSFP28 weli waa la isticmaali karaa, kaliya geli module kale. Tirada faraha dahabka ee OSFP-DD waa laba jibaar ka QSFP28.
QSFP-DD kasta waxa uu qaataa 25Gbps NRZ ama 50Gbps PAM4 qaabka calaamada. PAM4, waxay ku taageeri kartaa ilaa 400Gbps.
OSFP
OSFP, Octal Form Small Factor Pluggable, "O" waxay u taagan tahay "octal", oo si rasmi ah loo bilaabay Noofambar 2016.
Waxaa loogu talagalay in lagu isticmaalo 8 kanaal koronto si loo xaqiijiyo 400GbE (8 * 56GbE, laakiin 56GbE signal waxaa sameeyay 25G DML laser iyadoo la raacayo qaabeynta PAM4), cabbirkeeduna wax yar ayuu ka weyn yahay QSFP-DD. Matoorka indhaha iyo transceiver leh wattage sare ayaa leh wax yar ka fiican waxqabadka kulaylka.
CFP/CFP2/CFP4/CFP8
Centum gigabits Form Pluggable, mowjadaha dhererka cufan module isgaarsiinta indhaha. Heerka gudbintu wuxuu gaari karaa 100-400Gbpso
CFP waxaa loo qaabeeyey iyadoo lagu salaynayo interface-ka SFP, oo leh cabbir weyn oo taageeraya gudbinta xogta 100Gbps. CFP waxay taageeri kartaa hal calaamad oo 100G ah iyo hal ama in ka badan oo 40G ah.
Farqiga u dhexeeya CFP, CFP2 iyo CFP4 waa mugga. Mugga CFP2 waa nus ka mid ah CFP, iyo CFP4 waa rubuc ka mid ah CFP. CFP8 waa foom baakad ah oo si gaar ah loogu soo jeediyay 400G, cabbirkeeduna wuxuu u dhigmaa CFP2. Taageer 25Gbps iyo 50Gbps heerka kanaalka, oo xaqiiji heerka moduleka 400Gbps iyada oo loo marayo 16x25G ama 8 × 50 interface koronto.
