Esikhungweni sedatha, amamojula okubona akhona yonke indawo, kodwa abambalwa abakhuluma ngawo.Eqinisweni, amamojula abonakalayo aseyimikhiqizo esetshenziswa kakhulu esikhungweni sedatha.Izikhungo zedatha zanamuhla ikakhulukazi ziyi-fiber optic interconnections, futhi kukhona ukuxhunywa kwekhebula okumbalwa nokumbalwa, ngakho-ke ngaphandle kwamamojula optical, izikhungo zedatha azikwazi nhlobo ukusebenza.I-optical module iguqula isignali kagesi ibe isignali yokubona ekugcineni kokudlulisa ngokuguqulwa kwe-photoelectric, bese idlulisela isignali ye-optical kusignali kagesi ekugcineni kokwamukela ngemva kokudluliselwa. ngokusebenzisa i-fiber optical, okungukuthi, noma iyiphi imojuli ye-optical inezingxenye ezimbili zokudlulisa nokwamukela. Umsebenzi, yenza ukuguqulwa kwe-photoelectric kanye nokuguqulwa kwe-electro-optical, ukuze amamojula optical ahlukaniseke kumadivayisi emikhawulweni yomibili yenethiwekhi.Kunezinkulungwane zamadivayisi esikhungweni sedatha sosayizi ophakathi, futhi kuthatha okungenani izinkulungwane zamamojula optical ukuze kuzuzwe ukuxhumana okugcwele kwalawa madivayisi.Nakuba intengo ye-single optical module ingephezulu, inkulu kakhulu.Ngale ndlela, izindleko eziphelele zamamojula optical wokuthengwa kwedatha yesikhungo azikho phansi, futhi ngezinye izikhathi zedlula inani lokuthenga imishini yenethiwekhi evamile, ibe ingxenye yemakethe esikhungweni sedatha.
I-module ye-optical incane ngosayizi, kodwa umphumela wayo awuncane. Ngeke idlalwe ngaphandle kwanoma yisiphi isikhungo sedatha.Ngokukhula okuqhubekayo kwemakethe yesikhungo sedatha, imakethe yemojula ye-optical iye yaqhutshwa ngokuqondile. Eminyakeni emihlanu edlule, imakethe ye-optical module yomhlaba wonke ikhule ngokushesha. Kusukela ngo-2010, imali yokuthengisa yemakethe ye-optical module yomhlaba wonke yayingamadola ayizigidi eziyizinkulungwane ezingu-2.8 kuphela. Ngo-2014, imakethe yomhlaba wonke ye-optical module seyedlule i-US $ 4.1 billion, futhi imakethe ye-optical module kulindeleke ukuthi ithengiswe ngo-2019. Imali engenayo izokhuphuka ibe ngu-$ 6.6 billion. umthamo omkhulu. Kulinganiselwa ukuthi ngo-2017, imali ye-10G/40G/100G yomhlaba wonke ye-optical module izofinyelela ku-3.1 billion US dollar, futhi imakethe ye-optical module izoba ngaphezu kuka-55%. kanye namamojula we-100G optical azoba phezulu njenge-17% kanye ne-36% ngokulandelana, futhi isidingo esikhulu semakethe siye saholela abakhiqizi abaningi ukuba batshale imali kubo.Kuwukubona futhi inzuzo enkulu yemakethe ye-optical module, abantu abaningi bathatha izingozi futhi benze ibhizinisi. njengamamojula omgunyathi. Isibonelo, amamojula optical athengwa ngokuqondile kubakhiqizi bemojula ye-optical bese ethengiswa kwabanye abathengisi noma amakhasimende esikhungo sedatha.Kuphinde kube namamojula athile avele azenze abakhiqizi bamamojula avamile, angenangqondo, futhi ashintshanisa amanani aphezulu ngenzuzo ephansi.Uma lokhu I-module yokukhanya ephansi isetshenziswa, ingozi ingase ifike nganoma isiphi isikhathi.Amanye amamojula aphansi optical akhiqiza ukushisa okukhulu, amanye amamojula optical anamaphakheji amaningi angalungile, amanye amamojula optical azinzile, amanye amamojula optical anamarekhodi olwazi lwangaphakathi, njll. Sekuvele kunamamojula amaningi aphansi we-optical emakethe, okuye kwaphazamisa le makethe. . Kodwa-ke, lokhu kubonisa nokuthi imakethe ye-module optical ishisa kakhulu.Eqinisweni, ukuvula ngaphakathi kwe-module optical, ungabona ukuthi isakhiwo silula, futhi asibandakanyi izifunda eziyinkimbinkimbi. Okuwukuphela kwephuzu ukuthi inqubo yokukhiqiza iphakeme kakhulu, futhi ukukhiqizwa kwenqubo empofu kuzothinta kakhulu ikhwalithi ye-optical path, okungenzeka ihlotshaniswe nokukhanya kokuphela okuphambene. Amamojula awakwazi ukumiswa, noma amaphutha athile esixhumanisi avame ukukhiqizwa, okuthinta ukudluliselwa kwedatha.Ikakhulukazi namuhla, amamojula we-high-speed optical afana ne-40G ne-100G ngokuvamile adinga izidingo ezengeziwe zenqubo yokukhiqiza amamojula optical, ukuze akubona bonke abakhiqizi be-optical module. ingakhiqiza amamojula anjalo we-100G optical, okwenza futhi amamojula we-100G optical. Amanani ahlala esezingeni eliphezulu.I-optical module empeleni ingumkhiqizo onezidingo zobuchwepheshe eziphezulu. Okuqukethwe kwezobuchwepheshe kuphezulu. Izindleko zemodyuli ye-optical ngokwayo aziphezulu, kodwa inani elingeziwe lobuchwepheshe liphezulu. Ngenxa yokuthi kufanele kuthuthukiswe imojula ye-optical, ubuchwepheshe be-optical, isifunda kanye nenethiwekhi ngokuvamile kuyadingeka. Abacwaningi emikhakheni ehlukahlukene kufanele batshale ucwaningo oluningi lwesayensi. Ukufakwa kwabasebenzi kule ndawo kukhulu, futhi kufanele kubalwe ngezindleko zokwenza amamojula optical. Lokhu kugcina intengo yamamojula optical ezingeni eliphezulu.Yebo, uma kuqhathaniswa namaseva nemishini yenethiwekhi, inzuzo yamamojula optical iphakeme nakakhulu. Ngokungafani nezingxenye zemakethe ezifana neseva, inethiwekhi kanye nesitoreji, ukuncintisana kwezigaba zemakethe ye-optical kwanele.Ukuncintisana emakethe ye-optical module kuxubile. Abakhiqizi abaningana bangaphandle bangaphandle basebenza emakethe. Isimo sabahlinzeki abajwayelekile, abakhiqizi abaningana basekhaya be-optical module bangathola futhi imakethe eningi, ngokuvamile, abakhiqizi be-optical module bebengcono kakhulu eminyakeni yamuva. Ikakhulukazi ngesidingo esikhulayo samamojula we-40G / 100G optical esikhungweni sedatha, imakethe ilethe amathuba anele kubakhiqizi be-optical module, futhi lawa mamojula anesivinini esiphezulu anenzuzo ephakeme.
Akulula ukunikeza amamojula abonakalayo athembekile futhi ahlangabezana nezidingo zokusetshenziswa kwesikhungo sedatha.Eminyakeni embalwa edlule, obunye ubuchwepheshe esikhungweni sedatha buye bathuthukiswa ngokuqhubekayo, futhi izidingo zamamojula optical nazo ziyanda.Okokuqala ukuthi izinga liphezulu. Njengamanje, i-interface yeseva isuka ku-1G iye ku-10G, kanye nokuhlanganisashintshaisuka ku-10G iye ku-40G/100G. Amazinga we-25G kanye ne-400G nawo ayakhiwa. Uma izinga selakhiwe, ukwakheka nokuthuthukiswa kwemojuli ethile ye-optical nakho kuzoqala. Izophinde ithuthukise amandla omkhawulokudonsa wenethiwekhi wesikhungo sedatha.Okwesibili ukuba luhlaza kanye nokusetshenziswa kwamandla okuphansi. Ukusetshenziswa kwamandla kwesikhungo sedatha kukhulu kakhulu, futhi ukusetshenziswa kwamandla okubala ukushisa kuwukumosha okukhulu. Uma ukusetshenziswa kwamandla okusebenzayo kwe-module ye-10G optical kungu-3W, khona-ke ukusetshenziswa kwamandla kwebhodi lokushintsha i-48 million-megabit kuzofinyelela kuphela kumojula ye-optical. 144W, uma idivayisi yenethiwekhi enamabhodi angu-16 ifakiwe, kuyoba2300W, okulingana nesibani esingu-23 100W ngesikhathi esifanayo, esilambele kakhulu amandla.Okwesithathu ukuba nokuminyana okuphezulu nokonga isikhala. Nakuba ijubane lemojuli ye-optical liya ngokuya likhuphuka, lingaklanywa ukuthi libe lincane futhi libe lincane.I-GBIC optical module yangaphambili inezinga le-Gigabit kuphela, futhi ikhanda likhulu kune-10G yamanje.Imbobo ye-module ye-100G yangaphambilini yayicishe ibe yi-10CM ubude, futhi manje i-module ye-100G optical kanye nosayizi we-10G awahlukile.48 100G port densities can kwenziwe ebhodini elilodwa.Okwesine kuyizindleko eziphansi, futhi intengo ephezulu yamamojula we-100G optical nayo icindezele ezinye izimfuno zemakethe ngezinga elithile. Izikhungo eziningi zedatha zidikibala ngentengo ephezulu ye-100G amamojula optical.Ngenxa yokuthi hhayi kuphela i-module optical, kodwa futhi nemishini ehlonywe ngayo, idinga ukutshalwa kabusha, ukuze kungabi yizindleko ezincane.Uma i-module ye-100G optical ingancishiswa kakhulu ezindlekweni, maduze izoduma esikhungweni sedatha. Njengamanje, isikhungo sedatha esikwazi ukusebenzisa ukuxhumana kwe-100G asivamile. Ngakho-ke, akuwona umsebenzi olula ukunikeza amamojula wekhwalithi ephezulu. Kuyadingeka ukucwaninga ngokuqhubekayo futhi uthuthukise izinga lokukhiqiza lamamojula optical.
Nakuba imojula ye-optical incane, indima yayo esikhungweni sedatha ayikwazi ukushaywa indiva. Ikakhulukazi esikhungweni sedatha sanamuhla lapho izidingo zomkhawulokudonsa ziya ngokuya ziba phezulu, amamojula abonakalayo aze akhawulela ukuthuthukiswa kwezikhungo zedatha ngezinga elithile. Ngakho-ke, kuthenjwa ukuthi amabhizinisi amaningi azojoyina imakethe yamamojula optical ukukhuthaza ukuthuthukiswa okusheshayo kwemakethe ye-optical module. Akulona ihaba ukusebenzisa inkulumo ethi “izingcezu ezincane zinomphumela omkhulu” ukuchaza indima yamamojula okubona esikhungweni sedatha.
