ICorning yaziwa ngeGorilla Glass eyomeleleyo esetyenziswa ngabantu abaninzi kwiiselfowuni zabo.Kodwa inkampani iyafana ne-fiber optic cable.(Ifoto: Groman123, Flickr).
Xa kuchazwa iilinki zefiber optical, abantu basebenzisa amagama ahlukeneyo ukuchaza ikhonkco ngokohlobo lweziqhagamshelo kunye nenani lemicu ye-optical abayisebenzisayo kwikhonkco.I-Base-2 yeyona ilula ukuyiqonda kunye nokuyibona.Ngokusebenzisa i-Base-2 uxhumano, ikhonkco lethu lisekelwe ekwandeni kweefiber ezimbini, ezifana ne-LC duplex eqhelekileyo okanye i-SC duplex uxhumano.
Ngokwahlukileyo, uxhulumaniso lwe-Base-12 lusebenzisa izixhumanisi ezisekelwe kwi-12 increments, kunye ne-12 fiber optic connectors, njenge-MTP.Kutshanje, izisombululo zonxibelelwano lwe-Base-8 ziye zaqala ukubonakala.Inkqubo ye-Base-8 isasebenzisa izixhumi ze-MTP, kodwa ikhonkco yakhiwe ngokunyuka kweefiber ezisibhozo, kubandakanywa izixhumi ezisibhozo ze-fiber MTP.Ngokomzekelo, kwinkqubo ye-Base-8, asinayo i-12-core trunk optical cables.Sine-8-core trunk optical cables, i-16-core trunk optical cables, i-24-core trunk optical cables kunye ne-32-core trunk optical cables;zonke iintambo ze-Base-8 trunk zongezwa ngenani 8. ubuninzi.Umahluko phakathi kwe-Base-12 kunye ne-Base-8 iboniswe kumzobo ongezantsi.
Uqhagamshelo lwe-Base-12 lwaqala ukuziswa phakathi kwiminyaka yoo-1990.I-modular, i-high-density, inkqubo ye-cabling ecwangcisiweyo eyenziwe yi-IBM kunye ne-Corning, enokuthi ifakwe ngokukhawuleza kumaziko edatha ngelixa iphakamisa ubuninzi be-port kwindawo yokubeka.Amaziko edatha akhulile ukusuka kuqhagamshelo lwefayibha ezimbalwa kuphela ukuya kumaziko edatha anamawaka okanye amashumi amawaka amazibuko efayibha.Ngokucacileyo, ukubopha i-fiber jumpers ezimbini kwikona nganye yeziko ledatha kuya kukhokelela kwisiphithiphithi esingalawulekiyo nesingenakuthembeka.Njengoko i-TIA / EIA-568A i-fiber color coding standard isekelwe kumaqela e-fiber ayi-12, kunengqiqo ukuba uxhulumaniso oluphezulu lusekelwe kwinani le-12 increments.Ngoko ke, i-12 fiber MTP izixhumanisi kunye ne-Base-12 yokudibanisa yazalwa.
Iintambo zetrunk ezisekwe kwi-12-core optical fibers, ukuya kuthi ga kwi-144-core optical fibers, ziza kufumaneka kungekudala kwaye zisasazwe kwihlabathi jikelele.Iintambo ze-Base-12 ze-trunk zidla ngokusetyenziswa kumqolo womnatha wothungelwano, ukusuka kumnqamlezo oyintloko ukuya kwiindawo zokusabalalisa zengingqi, apho inani lemicu ye-optical likhulu kwaye i-high density iyadingeka.Ukuze uqhagamshelane namachweba kwiiseva, ukutshintshwa, kunye neeyunithi zokugcina, ezininzi izibuko zefayibha zisekelwe kwimicu emibini ye-optical, ngoko ke i-Base-12 ukuya kwiimodyuli zesebe le-Base-2 kunye neentambo zokubopha zisetyenziselwa ukubonelela izibuko ezimbini zefayibha kwizibuko ezimbini zefiber.Ekubeni inombolo ye-12 inokwahlulwa ngenani le-2, sinokubonelela ngokulula i-interface ye-fiber-fiber kwisixhobo sothungelwano kwaye sisebenzise ngokupheleleyo i-fiber optical ye-Base-12 intambo yomqolo.
Phantse iminyaka eyi-20, uqhagamshelo lwe-Base-12 lukhonze imboni yeziko ledatha kakuhle.Njengoko ukuthunyelwa kwe-12-core MTP izixhumi zikhule ngokukhawuleza kwiminyaka, i-MTP ngoku ibe ngumgangatho we-de facto kwiinethiwekhi ezininzi ze-backbone network.Nangona kunjalo, amaxesha ayatshintsha, kwaye kutshanje imfuno yoqhagamshelo lwe-Base-8 iye yabonakala.Oku kubangelwa kwiindidi ze-transceivers ezisetyenziselwa ukutshintshwa, iseva, kunye nabavelisi bokugcina kwizixhobo zabo, kunye ne-transceiver roadmap ekhokela imboni ukusuka kwi-10G Ethernet ukuya kwi-40G kunye ne-100G, kwaye ide ifike kwi-400G.
I-teknoloji ye-transceiver field iyatshintsha ngokukhawuleza, kodwa nabani na ofake i-40G iisekethe baya kukwazi ukuba enye yeentlobo eziqhelekileyo ze-transceivers yi-transceiver ye-QSFP, esebenzisa ii-fiber optical ezisibhozo.Singasebenzisa i-Base-12 yokudibanisa ukuxhuma kwiichweba ze-QSFP.Enyanisweni, abantu abaninzi abasebenzisa iisekethe ze-40G namhlanje banonxibelelwano lwe-Base-12 kwi-backbones yabo, kodwa nabafundi bemathematika abasisiseko banokuqonda indlela yokudibanisa i-12 fibers optical fibers.Ukufaka i-transceiver efuna iintsinga ezisibhozo kuphela kuthetha ukuba kukho imicu emine engasetyenziswanga.Kukho ezinye izisombululo kwiimarike ezinokufikelela kwi-100% yokusetyenziswa ngokupheleleyo kwe-backbone fiber ngokusebenzisa i-Base-12 ukuya kwimodyuli yokuguqulwa kwe-Base-8 okanye i-harness kule meko, kodwa oku kuya kwongeza izixhumi ezongezelelweyo ze-MTP kunye nokufakwa okongezelelweyo kwilahleko yekhonkco.Ngenxa yeendleko kunye nezizathu zokusebenza kwekhonkco, oku ngokuqhelekileyo akulunganga, ngoko ke ishishini linqume ukuba indlela engcono eya phambili iyafuneka.
Indlela engcono ludibaniso lwe-Base-8.Xa uthetha kunye ne-transceiver enkulu, i-switch, iseva, kunye nabavelisi bokugcina, kuyacaca ukuba okwangoku, ikamva elikufutshane, kunye nekamva elide lizele iintlobo ze-transceiver ezisekelwe kwi-Base-2 okanye i-Base-8 uxhumano.Ngamanye amazwi, ukuhanjiswa kwe-Ethernet ukusuka kwi-40G ukuya kwi-400G, zonke iindlela zikhokelela kwizisombululo zonxibelelwano lwe-fiber ezimbini kunye ne-eight-fiber.
Njengoko kuboniswe kwitheyibhile, kwindlela eya kwi-400G, kuya kubakho izisombululo zexesha elifutshane, njengesizukulwana sokuqala kunye nesibini se-OM3 / OM4 yokuhanjiswa okufanayo, ezicetywayo njenge-Base-32 kunye ne-Base-16 izixazululo.Nangona kunjalo, ukusuka kwiingxoxo zeCorning kunye ne-transceivers eyaziwayo, iiswitshi, iiseva, kunye nabathengisi bokugcina, ngenxa yeendleko zokuvelisa kunye nobunzima bokudibanisa (umzekelo, ngaba ufuna ngokwenene ukwazisa i-32-core fiber? Xhuma kwinethiwekhi yakho? ).Kulindeleke ukuba isisombululo sesizukulwana sesithathu, isisombululo se-Base-8, kwi-400G usebenzisa i-OM3 / OM4 i-fiber optical parallel transmission, iya kufumana ukwamkelwa kweemarike ngokubanzi.
Ekubeni inombolo ye-8 iyahlukana ngokupheleleyo ngenani le-2, uxhulumaniso lwe-Base-8 backbone lunokusetyenziswa lula kwi-transceiver system ye-fiber transceiver, njenge-Base-12 uxhumano.Nangona kunjalo, uxhulumaniso lwe-Base-8 lubonelela ngokugqithiseleyo kwiintlobo eziqhelekileyo ze-40G, i-100G, kunye ne-400G ye-transceiver, kuba uxhulumaniso lwe-Base-12 alulona lufanelekileyo kwiinkqubo ze-8-fiber transceiver.Ukubeka nje, uxhulumaniso lwe-Base-8 lubonelela ngesona sisombululo sijonge phambili ukuhlangabezana neemfuno zokuhanjiswa kwe-400G.
Ewe, ewe kwaye hayi.Kuxhomekeke kwindlela olichaza ngayo igama elithi "isetyenziswe kunye".Ukuba uthetha ukuxuba amacandelo ngokuthe ngqo kwaye udibanise i-trunk ye-Base-8 kwimodyuli ye-12-core, ngoko impendulo icacile "hayi".Amacandelo awayilwanga ukuba aqhagamshelwe ngokuthe ngqo omnye komnye.Ngoko ke, ukuyila kwe-Base-12 kunye ne-Base-8 ye-MTP ye-MTP inomahluko obonakalayo, ngoko kunokwenzeka ukuphepha ukuxuba i-Base-8 kunye ne-Base-12 components kwikhonkco elilodwa.Isizathu esibalulekileyo somahluko obonakalayo yi-Base-12 izintambo ze-trunk zihlala zineziqhagamshelo ze-MTP ezingafakwanga kuzo zombini iziphelo, kwaye kufuneka zisebenzise iimodyuli ezikhonjiweyo zokuqhawula.Nangona kunjalo, intambo ye-Base-8 ekhulayo ye-trunk yenziwe ngeziqhagamshelo zephini kuzo zombini iziphelo.Ke ngoko, ukuplaga intambo ye-Base-8 ye-trunk kwimodyuli ye-Base-12 yokuqhawuka ayisoze isebenze, kuba kuthetha ukuzama ukudibanisa iziqhagamshelo ezimbini eziphiniweyo kunye.Isizathu solu tshintsho kwiskimu sokulungiswa kwentambo ye-trunk kukuba ibonelela ngenzuzo yokuqinisekisa ukuba kungakhathaliseki ukuba i-Base-8 MTP jumpers isetyenziswe naphi na kwinethiwekhi, inokuhlala ineziqhagamshelo ezingaguqukiyo kuzo zombini iziphelo.Oku kwenza kube lula ukusasazwa kwenethiwekhi kwaye kuphelisa isidingo sokugcina uqwalaselo lwepin ezininzi ze-MTP jumpers.
Nangona kunjalo, ukuba "isetyenziswe kunye" ithetha ukuba zombini i-Base-8 kunye ne-Base-12 idibaniso kwiziko ledatha enye, ngoko impendulo ithi "ewe", nangona lo "ewe" unesilumkiso.Kufuneka kuqatshelwe ukuba i-Base-8 kunye ne-Base-12 ikhonkco kufuneka igcinwe ngokuzimeleyo, kuba njengoko kukhankanyiwe ngaphambili, i-Base-8 kunye ne-Base-12 amacandelo ngokwawo awanakutshintshi, kwaye i-Base-8 kunye ne-Base-12 components ayikwazi ukutshintshwa. ifakwe kwikhonkco elifanayo..Ngoko ke, kufuneka kuthathelwe ingqalelo xa ulawula isiseko somzimba weziko ledatha ukuqinisekisa ukuba i-Base-8 kunye ne-Base-12 components ayixutywanga kwikhonkco elifanayo.
Ekubeni inani le-12 likhulu kakhulu kunenombolo ye-8, uxhulumaniso lwe-Base-12 lubonelela ngenzuzo ye-fiber density ephezulu kwi-connector xa kuthelekiswa ne-Base-8, ngoko ke inani elikhulu leefayili linokufakwa ngokukhawuleza xa usebenzisa i-Base. -12 uqhagamshelwano.Nangona kunjalo, njengoko iisekethe ezininzi ze-40G kunye ne-100G zisetyenziselwa ukusebenzisa i-8-core fiber optic transceivers, iinzuzo zokufanisa inani leefayili kwi-backbone ye-MTP kunye nenani leefayili kwi-transceiver zihlala zidlula inzuzo ye-Base-12. uqhagamshelwano.Ukongeza, xa usebenzisa i-MTP ukuya kwi-LC duplex intambo yokubopha i-wiring yesebe ukuqhagamshela kwikhadi lomgca wokutshintsha, i-Base-8 intambo yokubopha ingahanjiswa ngokulula kuwo onke amakhadi omgca wenombolo yezibuko eziqhelekileyo, kuba onke amakhadi omgca oqhelekileyo aqulathe amazibuko amaninzi akhoyo. yahlula-hlulwa ngenombolo 4 (kuba i-Base-8 I-wiring harness ibonelela ngokudityaniswa kwe-LC duplex ezine).Kwimeko yeentambo ze-Base-12 ezibonelela ngodibaniso lwe-LC duplex ezintandathu, ezi zibophelelo azilula kangako ukuba zihambe ngendlela eya kumakhadi omgca kunye ne-16 okanye i-32 izibuko, kuba amanani 16 kunye ne-32 awahlulwanga ngokupheleleyo ngenombolo 6. Le theyibhile ilandelayo ichaza izibonelelo ezihambelanayo xa kuthelekiswa ne-Base-8 kunye ne-Base-12 yokudibanisa esetyenziswe kumaziko edatha.
Nangona i-fiber density ye-connector nganye ayinakuhoywa, kubantu abaninzi, isigqibo siya kubilisa ukuya kwisantya apho bafudukela khona kwi-40G kunye ne-100G yenethiwekhi yesantya.Nabani na onesicwangciso sokufuduka esikufutshane sokwamkela i-40G okanye i-100G kwiziko labo ledatha baya kuzuza kakhulu ekuthatheni uxhulumaniso lwe-Base-8 namhlanje.
I-Base-8 kunye ne-Base-12 uxhumano luya kuqhubeka lusetyenziswa kumaziko edatha kwiminyaka emininzi ezayo.Bobabini banenzuzo yabo, kwaye bobabini baya kuba nendawo kwiziko ledatha, apho ukusetyenziswa kwe-40 kunye ne-100G ukuhanjiswa yinto ephambili yokumisela.Ukuba usebenzisa uxhulumaniso lwe-Base-12 kwiziko lakho ledatha namhlanje kwaye wanelisekile ngalo, kulunge ngokugqibeleleyo ukuqhubeka usebenzisa i-Base-12.Uxhulumaniso lwe-Base-8 luyinketho eyongezelelweyo kwi-toolkit yomyili womnatha ukuqinisekisa ukuba iziko ledatha linexabiso eliphezulu kakhulu, inethiwekhi yexesha elizayo ekhoyo, kunye nendlela yokufuduka enokwandiswa ngokulula kwi-400G yokudluliselwa.
