Ni ubuhe bwoko bwa 100G optique module

Ibipimo bijyanye ninganda zitumanaho rya optique ahanini biva mumiryango nka IEEE, ITU, na MSA Industry Alliance.Hano hari amahame menshi kuri 100G module.Abakiriya barashobora guhitamo ubwoko bwigiciro cyingirakamaro ukurikije uburyo butandukanye bwo gusaba.Kubisabwa intera ngufi muri 300m, fibre ya multimode na lazeri ya VCSEL ikoreshwa cyane, naho kuri 500m-40km yohereza, fibre imwe imwe, DFB cyangwa EML ikoreshwa cyane.

Ugereranije na 2.5G, 10G cyangwa 40G sisitemu yo gukwirakwiza ibice byogukwirakwiza, 100G optique ikoresha ibyuma bifata ibyuma bifata amajwi kugirango ishushanye ibintu byose bya optique byerekana ibimenyetso bya optique kumurongo wamashanyarazi binyuze mubice bitandukanye kandi bitandukanya polarisiyasi, kandi ikoresha tekinoroji ikuze ya digitale ikuze mumashanyarazi. .Indangarugero ishyira mu bikorwa polarisiyasi demultiplexing, indishyi zingana zingana zingana, kugarura igihe, kugereranya icyiciro cyabatwara, kugereranya ibimenyetso no kugereranya umurongo.Mugihe hamenyekanye 100G yohereza optique, urukurikirane rwimpinduka zikomeye zikoranabuhanga zabaye muri modul ya optique ya 100G, harimo tekinoroji ya polarisiyonike igizwe na tekinoroji ya tekinoroji, ikoreshwa rya digitale ya coherent, tekinoroji yo mu gisekuru cya gatatu super amakosa yo gukosora code, nibindi, bityo igahaza abakoresha ibyo bakeneye. n'igihe.Ibikenewe byiterambere.

1. 100G optique module

Inzira nyamukuru yububiko bwa 100G optique irimo cyane cyane CXP, CFP, CFP2, CFP4, CFP8, na QSFP28.Hamwe niterambere mumyaka yashize, ibicuruzwa byoherejwe na CFP byagabanutse buhoro buhoro, kandi pake ya QSFP28 yatsindiye intsinzi muri rusange kubera ubunini bwayo no gukoresha ingufu nkeya, kandi ibyinshi mubipaki 200G na 400G bimaze kuvuka nabyo bikoresha QSFP- Ibikoresho bya DD.Kugeza ubu, amasosiyete menshi ya optique afite ibicuruzwa 100G bikurikirana muri QSFP28 kumasoko.

1.1 100G QSFP28 module optique

QSFP28 optique module ifite icyerekezo kimwe na QSFP optique module.Kuri QSFP28, buri muyoboro urashobora kohereza no kwakira amakuru agera kuri 28Gbps.Ugereranije na CFP4 optique module, QSFP28 optique module ni ntoya mubunini kuruta CFP4 optique.Moderi ya optique ya QSFP28 ifite ubucucike burenze module ya CFP4, kandi ingufu zikoreshwa mugihe gikora ntizishobora kurenga 3.5W, mugihe ingufu zikoreshwa mubindi moderi optique zisanzwe ziri hagati ya 6W na 24W.Duhereye kuriyi ngingo, gukoresha ingufu biri hasi cyane kurenza izindi 100G optique.

1.2 100G CXP module nziza

Igipimo cyo kohereza cya CXP optique module ni hejuru ya 12 * 10Gbps, kandi ishyigikira gucomeka.“C” igereranya 12 muri hexadecimal, naho umubare w’Abaroma “X” ugereranya ko buri muyoboro ufite umuvuduko wa 10Gbps.“P” bivuga gucomeka gushigikira gucomeka.CXP optique module igamije cyane cyane isoko rya mudasobwa yihuta, kandi ninyongera ya CFP optique module muri Ethernet data center.Mubuhanga, CFP optique module ikoreshwa hamwe na fibre optique ya fibre optique yo kohereza amakuru maremare.Kuberako isoko ya fibre fibre isaba panne-density nyinshi, ingano ntabwo yigeze iba nziza cyane kumasoko ya fibre fibre.

Moderi ya optique ya CXP ifite uburebure bwa 45mm na 27mm z'ubugari, kandi ni ntoya kuruta moderi ya optique ya XFP na CFP optique, bityo irashobora gutanga imiyoboro ihanitse.Byongeye kandi, moderi ya optique ya CXP ni sisitemu ihuza umuringa yagenwe n’ishyirahamwe ry’ubucuruzi rya Wireless Broadband Trade Association, ishobora gushyigikira 12 10GbE kuri 10GbE, 3 10G yohereza imiyoboro ya 40GbE cyangwa 12 10G ya Ethernet Fibre cyangwa umuyoboro wa 12 * QDR wohereza umurongo mugari. ibimenyetso.

1.3 100G CFP / CFP2 / CFP4 module nziza

Amasezerano ya CFP Multi-Source (MSA) asobanura ibisabwa ko modul ya hot-swappable optique ishobora gukoreshwa mugukwirakwiza imiyoboro ya 40G na 100G, harimo na Ethernet yihuta cyane (40GbE na 100GbE).Modire optique ya CFP ishyigikira ihererekanyabubasha kuri fibre imwe nuburyo butandukanye hamwe nibiciro bitandukanye, protocole hamwe nuburebure bwihuza, harimo interineti yose ishingiye kubitangazamakuru (PMD) yashyizwe mubipimo bya IEEE 802.3ba, naho umuyoboro wa 100G urimo PMD eshatu: 100GBASE -SR10 irashobora kohereza 100m, 100GBASE-LR4 irashobora kohereza 10KM, naho 100GBASE-ER4 irashobora kohereza 40KM.

CFP optique module yateguwe hashingiwe ku ntera ntoya ya optique ya module (SFP), ariko ni nini mu bunini kandi ishyigikira 100Gbps yohereza amakuru.Imigaragarire y'amashanyarazi ikoreshwa na CFP optique ikoresha imiyoboro 10 * 10Gbps yo kohereza muri buri cyerekezo (RX, TX), bityo rero ishyigikira ihinduka rya 10 * 10Gbps na 4 * 25Gbps.CFP optique module irashobora gushyigikira ikimenyetso kimwe 100G, OTU4, ikimenyetso cya 40G, OTU3 cyangwa STM-256 / OC-768.

Nubwo CFP optique module ishobora kumenya 100G ikoreshwa ryamakuru, bitewe nubunini bwayo, ntishobora guhaza ibikenewe byamakuru menshi.Muri uru rubanza, komite ya CFP-MSA yasobanuye ubundi buryo bubiri: CFP2 na CFP4 optique.
