Corning amadziwika ndi Galasi yolimba ya Gorilla yomwe anthu ambiri amagwiritsa ntchito pafoni zawo zam'manja.Koma kampaniyo ndi yofanana ndi chingwe cha fiber optic.(Chithunzi: Groman123, Flickr).
Pofotokoza maulalo olumikizira ulusi, anthu amagwiritsa ntchito mawu osiyanasiyana pofotokoza ulalowo molingana ndi mtundu wa zolumikizira ndi kuchuluka kwa ulusi wa kuwala womwe amagwiritsa ntchito pa ulalo.Base-2 ndiyosavuta kumvetsetsa ndikuwonera.Kupyolera mu kulumikizidwa kwa Base-2, ulalo wathu udakhazikitsidwa pakukula kwa ulusi awiri, monga LC duplex wamba kapena SC duplex kulumikizana.
Mosiyana ndi izi, maulumikizidwe a Base-12 amagwiritsa ntchito maulalo otengera 12 increments, ndi 12 fiber optic zolumikizira, monga MTP.Posachedwapa, njira zolumikizirana za Base-8 zayamba kuwonekera.Dongosolo la Base-8 limagwiritsabe ntchito zolumikizira za MTP, koma ulalowo umapangidwa mowonjezera ma ulusi asanu ndi atatu, kuphatikiza zolumikizira zisanu ndi zitatu za MTP.Mwachitsanzo, mu dongosolo la Base-8, tilibe zingwe za 12-core trunk Optical.Tili ndi zingwe 8-core trunk Optical zingwe, 16-core trunk Optical zingwe, 24-core trunk Optical zingwe ndi zingwe 32-core trunk Optical zingwe;zingwe zonse Base-8 thunthu ndi augmented ndi chiwerengero 8. kuchuluka.Kusiyana pakati pa Base-12 ndi Base-8 kukuwonetsedwa pachithunzi pansipa.
Kulumikizana kwa Base-12 kudayambitsidwa koyamba pakati pa zaka za m'ma 1990.Dongosolo lokhazikika, lokwera kwambiri, lopangidwa ndi IBM ndi Corning, lomwe limatha kutumizidwa mwachangu m'malo opangira ma data ndikukulitsa kuchuluka kwa madoko pamalo opangira rack.Malo osungira data akula kuchokera ku maulalo ochepa chabe kupita ku malo opangira data okhala ndi madoko masauzande kapena masauzande a fiber.Mwachiwonekere, kumangirira ma fiber jumpers awiri pakona iliyonse ya data center kumabweretsa chisokonezo chosasunthika komanso chosadalirika.Popeza kuti TIA/EIA-568A fiber color coding standard imachokera pamagulu 12 a fiber, ndizomveka kuti kulumikizana kwamphamvu kwambiri kukhazikitsidwe pa kuchuluka kwa 12.Chifukwa chake, zolumikizira 12 za fiber MTP ndi zolumikizira za Base-12 zidabadwa.
Zingwe zazikulu zozikidwa pa 12-core optical fibers, mpaka 144-core optical fibers, zipezeka posachedwa ndikutumizidwa padziko lonse lapansi.Zingwe za thunthu la Base-12 nthawi zambiri zimagwiritsidwa ntchito pamsana pa intaneti, kuchokera pamtanda waukulu kupita kumadera ogawa madera, komwe kuchuluka kwa ulusi wowoneka bwino ndi waukulu komanso kusalimba kwambiri kumafunika.Kuti agwirizane ndi madoko pa maseva, ma switch, ndi mayunitsi osungira, ma doko ambiri a fiber amachokera pazitsulo ziwiri za kuwala, kotero Base-12 ku Base-2 nthambi za nthambi ndi ma waya amagwiritsidwa ntchito kuti apereke madoko awiri a fiber kwa ma doko awiri a fiber.Popeza chiwerengero cha 12 chikhoza kugawidwa ndi chiwerengero cha 2, titha kupereka mosavuta mawonekedwe a-fiber-fiber ku zipangizo zamakono ndikugwiritsa ntchito mokwanira chingwe chamsana cha Base-12.
Kwa zaka pafupifupi 20, maulumikizidwe a Base-12 akhala akugwira ntchito bwino pamakampani a data.Pamene kutumizidwa kwa zolumikizira 12-core MTP kwakula kwambiri m'zaka zapitazi, MTP tsopano yakhala mulingo wokhazikika pama network ambiri amsana.Komabe, nthawi zikusintha, ndipo posachedwa kufunikira kwa kulumikizana kwa Base-8 kwawonekera.Izi ndichifukwa cha mitundu ya ma transceivers omwe amagwiritsidwa ntchito ndi makina osinthira, seva, ndi osungiramo zida zawo, komanso ma transceiver roadmap omwe amatsogolera makampani kuchokera ku 10G Ethernet kupita ku 40G ndi 100G, komanso mpaka 400G.
Ukadaulo wa gawo la transceiver ukusintha mwachangu, koma aliyense amene wayika mabwalo a 40G adzadziwa kuti imodzi mwa mitundu yodziwika bwino ya transceivers ndi QSFP transceiver, yomwe imagwiritsa ntchito ma fiber asanu ndi atatu.Titha kugwiritsa ntchito kulumikizana kwa Base-12 kuti tilumikizane ndi madoko a QSFP.M'malo mwake, anthu ambiri omwe amagwiritsa ntchito mabwalo a 40G masiku ano ali ndi kulumikizana kwa Base-12 kumbuyo kwawo, koma ngakhale ophunzira oyambira masamu amatha kumvetsetsa momwe angalumikizire ulusi wa 12.Kuyika transceiver yomwe imafuna ulusi eyiti yokha kumatanthauza kuti pali ulusi anayi womwe sunagwiritsidwe ntchito.Pali njira zina pamsika zomwe zitha kukwaniritsa 100% kugwiritsa ntchito kwathunthu kwa ulusi wa msana kudzera mu gawo la Base-12 kupita ku Base-8 kapena ma harni pankhaniyi, koma izi zidzawonjezera zolumikizira za MTP ndi zina zowonjezera pakutayika kwa ulalo.Pazifukwa zotsika mtengo komanso zolumikizirana, izi nthawi zambiri sizikhala zabwino, chifukwa chake makampani atsimikiza kuti njira yabwino yopitira patsogolo ndiyofunika.
Njira yabwino ndikulumikiza kwa Base-8.Poyankhula ndi ma transceiver akuluakulu, kusinthana, seva, ndi opanga zosungirako, zikuwonekeratu kuti panopa, posachedwapa, ndi tsogolo lalitali ndi lodzaza ndi mitundu ya transceiver yochokera ku Base-2 kapena Base-8 kugwirizana.Mwanjira ina, pakutumiza kwa Ethernet kuchokera ku 40G kupita ku 400G, misewu yonse imatsogolera ku njira ziwiri zolumikizira ma fiber ndi eyiti.
Monga momwe tawonetsera patebulo, panjira yopita ku 400G, padzakhala njira zina zosakhalitsa, monga mibadwo yoyamba ndi yachiwiri ya OM3 / OM4 yopatsirana yofanana, yomwe ikufotokozedwa ngati njira za Base-32 ndi Base-16.Komabe, kuchokera pazokambirana za Corning ndi ma transceivers odziwika bwino, ma switch, ma seva, ndi ogulitsa osungira, chifukwa cha ndalama zopangira ndi zovuta zolumikizira (mwachitsanzo, kodi mukufunadi kuyambitsa 32-core fiber? Lumikizani ku netiweki yanu? ).Zikuyembekezeka kuti yankho la m'badwo wachitatu, yankho la Base-8, la 400G pogwiritsa ntchito OM3 / OM4 optical fiber parallel transmission, lidzalandira kuvomerezeka kwa msika.
Popeza nambala 8 imagawanika kwathunthu ndi nambala 2, kugwirizana kwa msana wa Base-8 kungagwiritsidwe ntchito mosavuta pamakina awiri a fiber transceiver, monga kugwirizana kwa Base-12.Komabe, kugwirizana kwa Base-8 kumapereka kusinthasintha kwakukulu kwa mitundu yambiri ya 40G, 100G, ndi 400G ya transceiver, chifukwa kugwirizana kwa Base-12 sikuli koyenera kwa 8-fiber transceiver systems.Mwachidule, kugwirizana kwa Base-8 kumapereka yankho loyang'ana kutsogolo kuti likwaniritse zofunikira zotumizira 400G.
Chabwino, inde ndi ayi.Zimatengera momwe mumatanthauzira mawu oti "ntchito pamodzi".Ngati mukutanthauza kusakaniza zigawozo mwachindunji ndikulumikiza thunthu la Base-8 mu gawo la 12-core, ndiye kuti yankho ndilomveka "ayi".Zigawozo sizinapangidwe kuti zizilumikizidwa mwachindunji.Choncho, mapangidwe a machitidwe a Base-12 ndi Base-8 MTP ali ndi kusiyana kowonekera, kotero n'zotheka kupewa kusakaniza zigawo za Base-8 ndi Base-12 mu chiyanjano chimodzi.Chifukwa chachikulu cha kusiyana kwa mawonekedwe ndi zingwe za Base-12 zomwe nthawi zambiri zimakhala ndi zolumikizira za MTP zosagwirizana mbali zonse ziwiri, ndipo zimafunika kugwiritsa ntchito ma module opumira.Komabe, chingwe cha thunthu la Base-8 chimapangidwa ndi zolumikizira mapini mbali zonse ziwiri.Chifukwa chake, kulumikiza chingwe cha thunthu la Base-8 mu gawo la Base-12 sikungagwire ntchito, chifukwa kumatanthauza kuyesa kugwirizanitsa zolumikizira ziwiri zomangika pamodzi.Chifukwa cha kusintha kumeneku mu ndondomeko ya trunk cable fixation ndikuti imapereka mwayi woonetsetsa kuti ziribe kanthu komwe mabasiketi a Base-8 MTP amagwiritsidwa ntchito paliponse pa intaneti, amatha kukhala ndi zolumikizira zosakhazikika pamapeto onse awiri.Izi zimathandizira kutumiza ma netiweki ndikuchotsa kufunikira kosunga ma pini angapo a MTP jumper.
Komabe, ngati "zogwiritsidwa ntchito pamodzi" zimatanthauza kukhala ndi kugwirizana kwa Base-8 ndi Base-12 kumalo amodzi a deta, ndiye yankho ndi "inde", ngakhale kuti "inde" ili ndi chenjezo.Tiyenera kukumbukira kuti maulalo a Base-8 ndi Base-12 ayenera kusamalidwa paokha, chifukwa monga tanenera kale, zigawo za Base-8 ndi Base-12 sizingasinthidwe, ndipo zigawo za Base-8 ndi Base-12 sizingasinthidwe. alowetsedwa mu ulalo womwewo..Choncho, chisamaliro chiyenera kuchitidwa poyang'anira zowonongeka zakuthupi za data center kuti zitsimikizire kuti zigawo za Base-8 ndi Base-12 sizisakanizidwa mu ulalo womwewo.
Popeza chiwerengero cha 12 ndi chachikulu kwambiri kuposa chiwerengero cha 8, kugwirizana kwa Base-12 kumapereka mwayi wochuluka wa fiber mu cholumikizira poyerekeza ndi Base-8, kotero kuti ulusi wambiri ukhoza kukhazikitsidwa mofulumira mukamagwiritsa ntchito Base. - 12 kugwirizana.Komabe, monga maulendo ambiri a 40G ndi 100G akugwiritsidwa ntchito kuti agwiritse ntchito ma transceivers a 8-core fiber optic, ubwino wofanana ndi chiwerengero cha ulusi mumsana wa MTP kugwirizana ndi chiwerengero cha ulusi mu transceiver nthawi zambiri kuposa phindu la kachulukidwe ka Base-12. kulumikizana.Kuphatikiza apo, mukamagwiritsa ntchito MTP kupita ku LC duplex chingwe cholumikizira nthambi kuti mulumikizane ndi khadi yosinthira, chingwe cha Base-8 chimatha kuyendetsedwa mosavuta kumakhadi onse wamba wamba, chifukwa makhadi onse wamba ali ndi madoko ambiri omwe ali. zogawanika ndi nambala 4 (chifukwa Base-8 Chingwe cholumikizira chimapereka maulalo anayi a LC duplex).Pankhani ya ma harnesses a Base-12 omwe amapereka maulendo asanu ndi limodzi a LC duplex, ma harnesseswa sali ophweka kwambiri kuti ayendetse makhadi okhala ndi 16 kapena 32 madoko, chifukwa manambala 16 ndi 32 sagawidwa kwathunthu ndi nambala 6. limafotokoza zaubwino wachibale pofanizira kulumikizana kwa Base-8 ndi Base-12 komwe kumayikidwa m'malo opangira data.
Ngakhale kuchuluka kwa ulusi wa cholumikizira chilichonse sikunganyalanyazidwe, kwa anthu ambiri, chigamulocho chidzafika pa liwiro lomwe amasamukira ku liwiro la 40G ndi 100G network.Aliyense amene ali ndi ndondomeko yosamukira kufupi yafupipafupi kuti atenge 40G kapena 100G mu malo awo osungiramo deta adzapindula kwambiri potengera kugwirizana kwa Base-8 lero.
Malumikizidwe a Base-8 ndi Base-12 apitiliza kugwiritsidwa ntchito m'malo opangira ma data kwazaka zambiri zikubwerazi.Onse awiri ali ndi ubwino wawo, ndipo onse awiri adzakhala ndi malo mu data center, kumene kugwiritsa ntchito 40 ndi 100G kufalitsa ndi chinthu chofunikira kwambiri.Ngati mukugwiritsa ntchito kulumikizana kwa Base-12 pamalo anu a data lero ndipo mwakhutitsidwa nawo, ndikwabwino kupitiliza kugwiritsa ntchito Base-12.Kulumikizana kwa Base-8 ndi njira yowonjezera yowonjezera muzogwiritsira ntchito makina opangira maukonde kuti atsimikizire kuti malo opangira deta ali ndi njira zotsika mtengo kwambiri, zowonetsera zam'tsogolo zomwe zilipo, ndi njira yosamuka yomwe ingakulitsidwe mosavuta ku 400G kutumiza.
Lowani kuti mupeze mwayi wolembetsa maimelo, zoyitanira zochitika, mipikisano, mphatso ndi zina.
Umembala ndi waulere, ndipo chitetezo chanu ndi zinsinsi zanu zimatetezedwa.Yang'anani ndondomeko yathu yachinsinsi musanalembetse.
Pamapeto pake, laputopu iyi idakwaniritsa zomwe ndikuyembekeza pa laputopu ndikuyiphatikiza ndi mawonekedwe odabwitsa komanso kulemera kwake.
Monga Maserati kapena BMW m'ma laputopu, ndiyoyenera kwambiri kwa akatswiri omwe amafunikira firepower pansi pa hood, kukhathamiritsa kwapamwamba komanso luso lamasewera oyamba (masewera amasewera) pakati.
Chosindikizira chaching'ono ichi ndi chomwe ndimafunikira pa ma invoice ndi ntchito zina, monga kutumiza anzanga kapena malangizo atsatanetsatane, omwe ndimatha kusindikiza kuchokera pa foni yanga yam'manja kapena Webusaiti.
