Immisa nooc oo ah modules-ka 100G

Heerarka la xiriira warshadaha isgaarsiinta indhaha waxay inta badan ka yimaadaan ururada sida IEEE, ITU, iyo Isbahaysiga Warshadaha MSA.Waxaa jira halbeegyo badan oo loogu talagalay 100G modules.Macaamiishu waxay dooran karaan nooca moduleka ugu kharashka badan iyadoo loo eegayo xaaladaha kala duwan ee codsiga.Codsiyada fogaanta gaaban ee gudaha 300m, fiber multimode fiber iyo VCSEL lasers ayaa inta badan loo isticmaalaa, iyo gudbinta 500m-40km, fiber hal-mode ah, DFB ama EML lasers ayaa inta badan la isticmaalaa.

Marka la barbar dhigo 2.5G, 10G ama 40G nidaamyada gudbinta mawjada dhererka dhererka, 100G gudbinta indhaha waxay isticmaashaa aqbalayaasha isku xidhan ee dhijitaalka ah si ay u sawirto dhammaan sifooyinka indhaha ee calaamadaha indhaha ee qaybta korantada iyada oo loo marayo kala duwanaanshaha wejiga iyo kala duwanaanshaha kala duwanaanshaha, oo u adeegsada tignoolajiyada farsamaynta calaamadaha dhijitaalka ah ee qaan-gaadhka ah ee qaybta korantada .Goobtu waxa ay fulisaa kala-saarista dabaylaha, gunnada sinnaanta naafanimada kanaalka, soo kabashada wakhtiga, qiyaasta marxaladda side, qiimaynta astaanta iyo goynta toosan.Iyadoo la ogaanayo gudbinta indhaha ee 100G, isbedelo tikniyoolajiyadeed oo isdaba joog ah ayaa ka dhacay 100G modules indhaha, oo ay ku jiraan polarization multiplexing technology modulation, technology soo dhawaynta isku xidhan ee dhijitaalka ah, jiilka saddexaad ee sixitaanka teknoolajiyada qaladka super, iwm, sidaas darteed qancinta baahida isticmaalayaasha iyo waqtiga.Baahida horumarka.

1. 100G module indhaha

Xirmooyinka guud ee 100G modules indhaha inta badan waxaa ka mid ah CXP, CFP, CFP2, CFP4, CFP8, iyo QSFP28.Horumarka sanadihii la soo dhaafay, shixnadaha alaabooyinka taxanaha CFP ayaa si tartiib tartiib ah hoos ugu dhacay, xirmada QSFP28 waxay ku guuleysatay guusha guud sababtoo ah cabbirkeeda yar iyo isticmaalka awoodda hoose, iyo inta badan xirmooyinka cusub ee 200G iyo 400G waxay sidoo kale isticmaalaan QSFP- Xirmooyinka DDWaqtigan xaadirka ah, inta badan shirkadaha moodeelka indhaha ayaa leh badeecooyin taxane ah oo 100G ah oo ku jira xirmada QSFP28 ee suuqa.

1.1 100G QSFP28 module indhaha

Qaybta indhaha ee QSFP28 waxay leedahay fikrad naqshadeed la mid ah moduleka indhaha ee QSFP.QSFP28, kanaal kasta wuxuu diri karaa oo heli karaa xogta ilaa 28Gbps.Marka la barbar dhigo cutubyada indhaha ee CFP4, Qaybaha indhaha ee QSFP28 way ka yar yihiin cabbirka qaybaha indhaha ee CFP4.Qalabka indhaha ee QSFP28 wuxuu leeyahay faa'iido cufnaan ah oo ka sarreeya moduleka indhaha ee CFP4, iyo isticmaalka korantada inta lagu jiro hawlgalka inta badan kama badna 3.5W, halka isticmaalka korantada qaybaha kale ee indhaha ay badanaa u dhexeeyaan 6W iyo 24W.Marka laga eego aragtidan, isticmaalka korantadu aad ayuu uga hooseeyaa qaybaha kale ee indhaha ee 100G.

1.2 100G CXP module indhaha

Heerka gudbinta ee moduleka indhaha ee CXP waa mid aad u sarreeya sida 12 * 10Gbps, waxayna taageertaa xirid kulul."C" waxay ka dhigan tahay 12 hexadecimal, lambarka Roomaanka "X" wuxuu u taagan yahay in kanaal kasta uu leeyahay xadiga gudbinta 10Gbps."P" waxa loola jeedaa fur-gaab taageeraya xidhidh kulul.Qalabka indhaha ee CXP waxaa inta badan loogu talagalay suuqa kombuyuutarrada xawaaraha sare leh, waana kabka moduleka indhaha ee CFP ee xarunta xogta Ethernet.Farsamo ahaan, modules-yada indhaha ee CFP ayaa si wada jir ah loo adeegsadaa fiilooyinka indhaha ee multimode si loogu gudbiyo xogta fogaanta gaaban.Sababtoo ah suuqa fiber multimode wuxuu u baahan yahay muraayado cufan oo sarreeya, cabbirka si dhab ah looma hagaajin suuqa fiber-ka-badan.

Qaybta indhaha ee CXP waa 45mm dheer iyo 27mm ballaaran, waana ka yar yahay moduleka indhaha ee XFP iyo moduleka indhaha ee CFP, si ay u bixiso shabakad cufnaanta sare leh.Intaa waxaa dheer, moduleka indhaha ee CXP waa nidaam isku xiraha naxaasta ah oo ay qeexeen Ururka Ganacsiga Wireless Broadband Trade Association, kaas oo taageeri kara 12 10GbE ee ​​10GbE, 3 10G isku xirka isku xirka 40GbE kanaalka ama 12 10G Ethernet Fiber Channel ama wireless 12 * QDR gudbinta isku xirka balaastikada. calaamadaha.

1.3 100G CFP/CFP2/CFP4 module indhaha

Heshiiska CFP Multi-Source Agreement (MSA) wuxuu qeexayaa shuruudaha in modules-ka-kuleelka ah ee la isku bedeli karo lagu dabaqi karo gudbinta shabakada 40G iyo 100G, oo ay ku jiraan jiilka xiga ee xawaaraha sare ee Ethernet (40GbE iyo 100GbE).Qalabka indhaha ee CFP wuxuu taageeraa gudbinta hal-hab iyo fiilooyinka qaab-badan leh oo leh heerar kala duwan, borotokool iyo dhererka isku xirka, oo ay ku jiraan dhammaan warbaahinta-ku-tiirsanaanta (PMD) ee ku jira heerka IEEE 802.3ba, iyo shabakadda 100G waxay ka kooban tahay saddex PMDs: 100GBASE -SR10 wuxuu gudbin karaa 100m, 100GBASE-LR4 wuxuu gudbin karaa 10KM, 100GBASE-ER4 wuxuu gudbin karaa 40KM.

Module-ka indhaha ee CFP waxa loo nashqadeeyay iyada oo lagu salaynayo interface-ka moduleka indhaha ee yar-yar ee la xidhi karo (SFP), laakiin cabbirkiisu wuu ka weyn yahay waxana uu taageeraa gudbinta xogta 100Gbps.Isku xirka korantada ee loo isticmaalo moduleka indhaha ee CFP wuxuu isticmaalaa 10 * 10Gbps kanaalka gudbinta jiho kasta (RX, TX), sidaa darteed waxay taageertaa beddelka labada dhinac ee 10 * 10Gbps iyo 4 * 25Gbps.Qalabka indhaha ee CFP wuxuu taageeri karaa hal calaamad oo 100G ah, OTU4, calaamad 40G ah, OTU3 ama STM-256/OC-768.

Inkasta oo moduleka indhaha ee CFP uu ogaan karo codsiyada xogta 100G, sababtoo ah cabbirkiisa weyn, ma dabooli karo baahida xarumaha xogta cufnaanta sare.Xaaladdan oo kale, guddiga CFP-MSA ayaa qeexay laba nooc oo kale: CFP2 iyo CFP4 modules indhaha.
