I-Corning yaziwa nge-Gorilla Glass eqinile esetshenziswa abantu abaningi kumaselula abo.Kodwa inkampani ifana nekhebula le-fiber optic.(Isithombe: Groman123, Flickr).
Lapho bechaza izixhumanisi ze-optical fibre, abantu basebenzisa amagama ahlukahlukene ukuchaza isixhumanisi ngokuya ngohlobo lwezixhumi kanye nenani lemicu yokubona abayisebenzisayo kusixhumanisi.I-Base-2 iyona elula ukuyiqonda nokuyibona ngeso lengqondo.Ngokuxhunywa kwe-Base-2, isixhumanisi sethu sisekelwe ekwandeni kwemicu emibili, njengoxhumano oluvamile lwe-LC duplex noma lwe-SC duplex.
Ngokuphambene, ukuxhumana kwe-Base-12 kusebenzisa izixhumanisi ezisekelwe ku-12 increments, nezixhumi ezingu-12 ze-fiber optic, njenge-MTP.Muva nje, izixazululo zokuxhumanisa i-Base-8 seziqalile ukuvela.Uhlelo lwe-Base-8 lusasebenzisa izixhumi ze-MTP, kodwa isixhumanisi sakhiwe ngokunyuka kwamafayibha ayisishiyagalombili, okuhlanganisa nezixhumi eziyisishiyagalombili ze-fiber MTP.Isibonelo, ohlelweni lwe-Base-8, asinawo amakhebuli e-optical trunk angu-12-core.Sinezintambo ezingu-8-core trunk optical cables, 16-core trunk optical cables, 24-core trunk optical cables kanye ne-32-core trunk optical cables;zonke izintambo ze-Base-8 trunk zengezwe ngenombolo 8. ubuningi.Umehluko phakathi kwe-Base-12 ne-Base-8 uboniswa esithombeni esingezansi.
Ukuxhumana kwe-Base-12 kwethulwa okokuqala maphakathi nawo-1990.I-modular, high-density, isistimu yekhebula ehlelekile eyakhiwe yi-IBM ne-Corning, engasatshalaliswa ngokushesha ezikhungweni zedatha kuyilapho kukhulisa ukuminyana kwembobo endaweni yokubeka.Izikhungo zedatha zikhulile kusukela ekuxhumekeni kwefayibha embalwa kuphela kuya ezikhungweni zedatha ezinezinkulungwane noma amashumi ezinkulungwane zamachweba wefayibha.Ngokusobala, ukuxhuma ama-fiber jumper amabili ekhoneni ngalinye lesikhungo sedatha kuzoholela ezinxushunxushwini ezingalawuleki nezingathembekile.Uma kubhekwa ukuthi izinga lokufaka ikhodi lombala we-TIA/EIA-568A lisekelwe emaqenjini angu-12 efayibha, kunengqondo ukuthi uxhumo oluminyanisayo lusekelwe enanini elingu-12.Ngakho-ke, izixhumi eziyi-12 ze-fiber MTP kanye nokuxhumeka kwe-Base-12 zazalwa.
Izintambo ze-trunk ezisekelwe ku-12-core optical fibers, kufika ku-144-core optical fibers, zizotholakala maduze futhi zisetshenziswe emhlabeni jikelele.Izintambo ze-Base-12 trunk zivame ukusetshenziswa kumgogodla wenethiwekhi, kusukela ekuxhumaneni okuyinhloko kuya ezindaweni zokusabalalisa zesifunda, lapho inani lemicu ye-optical likhulu futhi kudingeka ukuminyana okuphezulu.Ukuze kuxhunywe kumachweba kumaseva, amaswishi, namayunithi okugcina, izimbobo eziningi zefayibha zisekelwe kumafayibha okubona amabili, ngakho-ke amamojula egatsha e-Base-12 kuya ku-Base-2 namahhanisi ezintambo asetshenziselwa ukuhlinzeka ngezimbobo zefayibha ezimbili zezimbobo ezimbili zefayibha.Njengoba inombolo engu-12 ingahlukaniswa ngenombolo 2, singanikeza kalula isikhombimsebenzisi se-dual-fiber emishinini yenethiwekhi futhi sisebenzise ngokugcwele i-fiber optical yekhebula elingemuva le-Base-12.
Cishe iminyaka engama-20, ukuxhumana kwe-Base-12 kusebenze kahle imboni yesikhungo sedatha.Njengoba ukuthunyelwa kwezixhumi ezingu-12-core MTP kuye kwakhula ngokuphawulekayo phakathi neminyaka edlule, i-MTP manje isiphenduke indinganiso ye-de facto kumanethiwekhi amaningi omgogodla wesikhungo sedatha.Kodwa-ke, izikhathi ziyashintsha, futhi muva nje isidingo sokuxhumeka kwe-Base-8 sesiyabonakala.Lokhu kungenxa yezinhlobo zama-transceivers asetshenziswa abakhiqizi be-switch, iseva, kanye nesitoreji kumishini yabo, kanye ne-transceiver roadmap eqondisa imboni kusuka ku-10G Ethernet kuya ku-40G naku-100G, futhi kuze kufike ku-400G.
Ubuchwepheshe benkambu ye-transceiver buyashintsha ngokushesha, kodwa noma ubani ofake izifunda ze-40G uzokwazi ukuthi enye yezinhlobo ezivame kakhulu ze-transceivers yi-transceiver ye-QSFP, esebenzisa imicu ye-optical eyisishiyagalombili.Singasebenzisa ukuxhumana kwe-Base-12 ukuze sixhume kumachweba we-QSFP.Eqinisweni, abantu abaningi abasebenzisa izifunda ze-40G namuhla banokuxhunywa kwe-Base-12 emhlane wabo, kodwa ngisho nabafundi bezibalo eziyisisekelo bangaqonda indlela yokuxhuma i-12 optical fibers.Ukufaka i-transceiver edinga imicu eyisishiyagalombili kuphela kusho ukuthi kunemicu emine engasetshenzisiwe.Kukhona ezinye izixazululo emakethe ezingafinyelela ukusetshenziswa okugcwele kwe-100% ye-backbone fiber ngokusebenzisa i-Base-12 kuya ku-Base-8 imojula yokuguqulwa noma i-harness kuleli cala, kodwa lokhu kuzokwengeza izixhumi ze-MTP ezengeziwe kanye nokufakwa okwengeziwe ekulahlekeni kwesixhumanisi.Ngezizathu zezindleko nezixhumanisi zokusebenza, lokhu ngokuvamile akufanelekile, ngakho-ke imboni inqume ukuthi indlela engcono yokuqhubekela phambili iyadingeka.
Indlela engcono kakhulu i-Base-8 uxhumano.Uma ukhuluma nabakhiqizi abakhulu be-transceiver, i-switch, iseva, kanye nesitoreji, kuyacaca ukuthi okwamanje, ikusasa eliseduze, kanye nekusasa lesikhathi eside kugcwele izinhlobo ze-transceiver ezisekelwe ekuxhumekeni kwe-Base-2 noma i-Base-8.Ngamanye amazwi, ekudluliselweni kwe-Ethernet kusuka ku-40G kuya ku-400G, yonke imigwaqo iholela kuzixazululo zokuxhumanisa ama-fiber amabili kanye nesishiyagalombili.
Njengoba kuboniswe etafuleni, endleleni eya ku-400G, kuzoba nezixazululo zesikhashana esifushane, njengesizukulwane sokuqala nesesibili se-OM3 / OM4 yokudlulisa okufanayo, okuhlongozwayo njenge-Base-32 ne-Base-16 izixazululo.Kodwa-ke, kusukela ezingxoxweni zikaCorning nama-transceivers aziwayo, amaswishi, amaseva, nabathengisi besitoreji, ngenxa yezindleko zokukhiqiza kanye nobunkimbinkimbi besixhumi (isibonelo, ingabe ufuna ngempela ukwethula i-32-core fiber? Xhuma kunethiwekhi yakho? ).Kulindeleke ukuthi isisombululo sesizukulwane sesithathu, isisombululo se-Base-8, se-400G sisebenzisa i-OM3/OM4 optical fiber parallel transmission, sizothola ukwamukelwa kwemakethe okubanzi.
Njengoba inombolo engu-8 ihlukaniseka ngokuphelele ngenombolo 2, uxhumano lwe-Base-8 backbone lungasetshenziswa kalula ohlelweni lwe-dual fiber transceiver, njengokuxhumana kwe-Base-12.Kodwa-ke, ukuxhumeka kwe-Base-8 kunikeza ukuguquguquka okukhulu kwezinhlobo ezivame kakhulu ze-40G, i-100G, ne-400G ye-transceiver, ngoba ukuxhumeka kwe-Base-12 akulona elilungile ku-8-fiber transceiver systems.Kalula nje, uxhumano lwe-Base-8 luhlinzeka ngesisombululo esibheke phambili kakhulu ukuhlangabezana nezidingo zokudlulisela kwe-400G.
Yebo, yebo futhi cha.Kuya ngokuthi ulichaza kanjani igama elithi “setshenziswa ndawonye”.Uma uqonde ukuxuba izingxenye ngokuqondile futhi uxhume isiqu se-Base-8 kumojula ye-12-core, impendulo ithi "cha" ecacile.Izingxenye aziklanyelwe ukuthi zixhunywe zodwa.Ngakho-ke, ukuklanywa kwezinhlelo ze-Base-12 ne-Base-8 MTP kunomehluko obonakalayo, ngakho-ke kungenzeka ukugwema ukuxuba izingxenye ze-Base-8 ne-Base-12 kusixhumanisi esisodwa.Isizathu esiyinhloko somehluko obonakalayo izintambo ze-Base-12 trunk ngokuvamile zinezixhumi ze-MTP ezingaphiniwe kuzo zombili iziphetho, futhi zidinga ukusebenzisa amamojula aphiniwe wokuphumula.Kodwa-ke, intambo ye-trunk ye-Base-8 evelayo ikhiqizwa ngezixhumi zephini kuzo zombili iziphetho.Ngakho-ke, ukuxhuma ikhebula le-Base-8 trunk module ye-Base-12 breakout akusoze kwasebenza, ngoba kusho ukuzama ukuhlanganisa izixhumi ezimbili eziphiniwe.Isizathu salolu shintsho ohlelweni lokulungisa ikhebula le-trunk ukuthi lunikeza inzuzo yokuqinisekisa ukuthi kungakhathaliseki ukuthi i-Base-8 MTP jumpers isetshenziswa kuphi kunethiwekhi, ingaba nezixhumi ezingagxilile kuzo zombili iziphetho.Lokhu kwenza ukuthunyelwa kwenethiwekhi kube lula futhi kuqede isidingo sokugcina ukucushwa kwamaphinikhodi amaningi kuma-jumpers e-MTP.
Kodwa-ke, uma "kusetshenziswa ndawonye" kusho ukuba nokuxhumana kokubili kwe-Base-8 ne-Base-12 endaweni efanayo yedatha, impendulo ithi "yebo", nakuba lo "yebo" unesexwayiso.Kufanele kuqashelwe ukuthi izixhumanisi ze-Base-8 ne-Base-12 kufanele zigcinwe ngokuzimela, ngoba njengoba kushiwo ngaphambili, izingxenye ze-Base-8 ne-Base-12 ngokwazo azishintsheki, futhi izingxenye ze-Base-8 ne-Base-12 azikwazi ukushintshwa. ifakwe kusixhumanisi esifanayo..Ngakho-ke, kudingeka kuqashelwe lapho kulawulwa ingqalasizinda yesendlalelo esibonakalayo sesikhungo sedatha ukuze kuqinisekiswe ukuthi izingxenye ze-Base-8 ne-Base-12 azixutshwa kusixhumanisi esifanayo.
Njengoba inombolo ye-12 inkulu kakhulu kunenombolo ye-8, uxhumano lwe-Base-12 luhlinzeka ngenzuzo ye-fiber density ephakeme kusixhumi uma kuqhathaniswa ne-Base-8, ngakho-ke inani elikhulu lemicu ingafakwa ngokushesha uma usebenzisa i-Base. -12 uxhumano.Kodwa-ke, njengoba izifunda eziningi ze-40G ne-100G zisetshenziselwa ukusebenzisa i-8-core fiber optic transceivers, izinzuzo zokufanisa inani lemicu ekuxhumekeni kwe-backbone ye-MTP nenani lezintambo ku-transceiver ngokuvamile zidlula izinzuzo ze-Base-12. uxhumano.Ukwengeza, lapho Uma usebenzisa i-MTP kuya ku-LC izintambo zezintambo eziphindwe kabili zegatsha ukuze uxhume ekhadini lomugqa wokushintsha, izintambo ze-Base-8 zingahanjiswa kalula kuwo wonke amakhadi omugqa wezinombolo zembobo ezivamile, ngoba wonke amakhadi olayini avamile aqukethe izimbobo eziningi ihlukaniseka ngenombolo 4 (ngoba i-Base-8 Ihhanisi lezintambo lihlinzeka ngezixhumanisi ezine ze-LC duplex).Endabeni yamahhanisi e-Base-12 ahlinzeka ngoxhumo oluyiduplex lwe-LC oluyisithupha, lawa mahhanisi akulula kangako ukuwahambisa kumakhadi alayini anezimbobo eziyi-16 noma ezingama-32, ngoba izinombolo 16 no-32 azihlukaniseki ngokuphelele ngenombolo 6. Ithebula elilandelayo ichaza izinzuzo ezihlobene lapho kuqhathaniswa uxhumo lwe-Base-8 ne-Base-12 olufakwe ezikhungweni zedatha.
Nakuba ukuminyana kwefiber yesixhumi ngasinye kungenakunakwa, kubantu abaningi, isinqumo sizobilisa ngesivinini abathuthela ngaso ku-40G kanye nesivinini senethiwekhi ye-100G.Noma ubani onohlelo oluseduze lokufuduka ukuze amukele i-40G noma i-100G esikhungweni sabo sedatha uzozuza kakhulu ngokwamukela ukuxhumana kwe-Base-8 namuhla.
Izixhumanisi ze-Base-8 ne-Base-12 zizoqhubeka zisetshenziswa ezikhungweni zedatha iminyaka eminingi ezayo.Bobabili banezinzuzo zabo, futhi bobabili bazoba nendawo esikhungweni sedatha, lapho ukusetshenziswa kwe-40 ne-100G yokudlulisela kuyisici esibalulekile esinqumayo.Uma usebenzisa uxhumano lwe-Base-12 esikhungweni sakho sedatha namuhla futhi wanelisekile yiso, kuhle kakhulu ukuqhubeka usebenzisa i-Base-12.Ukuxhumeka kwe-Base-8 kumane kuyinketho eyengeziwe ku-toolkit yomklami wenethiwekhi ukuze kuqinisekiswe ukuthi isikhungo sedatha sinenethiwekhi engabizi kakhulu, enobufakazi besikhathi esizayo etholakalayo, kanye nendlela yokufuduka enganwetshwa kalula ekudlulisweni kwe-400G.
