I-5G, idatha enkulu, i-intelligence intelligence kunye nezinye iteknoloji zineemfuno eziphezulu zokucwangcisa idatha kunye nenethiwekhi ye-bandwidth. Amaziko edatha ye-Intanethi.Indlela echanekileyo yokwandisa i-bandwidth yenethiwekhi kukunyusa i-bandwidth yenethiwekhi ye-port eyodwa ukusuka kwi-40G ukuya kwi-100G, ukusuka kwi-100G ukuya kwi-200G, okanye nangaphezulu, ngaloo ndlela yandisa i-bandwidth yazo zonke iziko ledatha.Iingcali ziqikelele ukuba uninzi lwe-400GbE ukuthunyelwa kuya kuqala kwi-2019. 400GbEiiswitshiiya kusetyenziswa njengomqolo okanye umbindiiiswitshikumaziko edatha amakhulu, kunye nomqolo okanye umqoloiiswitshikumaziko edatha yefu yabucala kunye noluntu, ukwazi ukuba i-100G nayo iyathandwa. Kwiminyaka emithathu edlulileyo, ngoku kuyimfuneko ukutshintshela kwi-400G, kwaye i-bandwidth yenethiwekhi iyanda ngokukhawuleza nangokukhawuleza.
Ngakolunye uhlangothi, kukho imfuno eqinile yeemodyuli zesantya esiphezulu kwiziko ledatha, kwaye ngakolunye uhlangothi, izinga lokungaphumeleli kwemodyuli liphezulu. iphezulu kakhulu.Ngokuqinisekileyo, inkqubo eyinkimbinkimbi yezi modyuli ezikhawulezayo ziphezulu kakhulu kuneemodyuli eziphantsi. Ngokomzekelo, imodyuli ye-40G ye-optical ibotshwe ngokuyimfuneko ngamashaneli amane e-10G. Ngexesha elifanayo, lilingana ne-10Gs ezine ezisebenzayo, nje ukuba kukho ingxaki. I-40G yonke ayinakuphinda isetyenziswe, kwaye izinga lokungaphumeleli liphezulu kune-10G, kwaye imodyuli ye-optical idinga ukulungelelanisa umsebenzi weendlela ezine ze-optical, kwaye amathuba okuba impazamo iphezulu ngokwemvelo.I-100G ingaphezulu kakhulu, ezinye ziboshwe ngamashaneli e-10 10G, kwaye ezinye zisebenzisa iteknoloji entsha ye-optical, eya kwandisa amathuba okuba nokwenzeka kwempazamo.I-100G ingaphezulu kakhulu, ezinye ziboshwe ngamashaneli e-10 10G, kwaye ezinye zisebenzisa iteknoloji entsha ye-optical, eya kwandisa amathuba. Ukungakhankanywa kwesantya esiphezulu, ukuvuthwa kobugcisa akukho phezulu, njenge-400G iseyiteknoloji kwilabhoratri, iya kwaziswa kwimarike ngo-2019, kuya kubakho uvuthondaba oluncinci lwezinga lokungaphumeleli, kodwa imali ayikho ekuqaleni. Kuya kuba ninzi, kwaye njengoko iteknoloji iqhubeka nokuphucula, ndiyakholelwa ukuba iya kuzinza njengemodyuli ye-vulgar.Cinga ukufumana imodyuli ye-1G ye-GBIC kwiminyaka eyi-20 edlulileyo. Kuyafana nokuziva usebenzisa i-200G ngoku. Akunakuphepheka ukuba imveliso entsha iya kunyuka kwizinga lokungaphumeleli kwixesha elifutshane.
Ngethamsanqa, impazamo yemodyuli ye-optical inempembelelo encinci kwinkonzo. Amakhonkco kwiziko ledatha axhaswa ngokungafunekiyo. Ukuba imodyuli enye yekhonkco ye-optical inengxaki, inkonzo inokuthatha amanye amakhonkco. Ukuba yipakethi yephutha ye-CRC, inokuphinda idlulise ulawulo lwenethiwekhi. Kwangoko kufunyaniswe ukuba inkqubo yokutshintsha yenziwe kwangoko, ngoko ke ukungaphumeleli kwemodyuli ye-optical kunqabile ukuba kube nempembelelo enkulu kwishishini. Kwiimeko ezinqabileyo, imodyuli yokubona inokubangela ukusilela kwezibuko lesixhobo, okunokubangela ukuba isixhobo siphelele sijingale. Le meko ibangelwa ikakhulu kukuphunyezwa kwesixhobo esingafanelekanga, kwaye ayifane yenzeke. Phakathi kweemodyuli ezininzi ze-optical kunye nezixhobo zidibene Ngokukhululekileyo, nangona ziqhagamshelwe kunye, azinabudlelwane bokudibanisa. Ngoko ke, nangona ukusetyenziswa kweemodyuli ze-high-speed optical zibi kakhulu, impembelelo kwishishini ayikho kakhulu. Ngokuqhelekileyo, akuyi kutsala ingqalelo yabantu. Kufunyenwe ukuba iphutha litshintshwe ngokuthe ngqo, kwaye ixesha lokugcinwa kwemodyuli ye-high-speed optical nayo ide. Impazamo isimahla. Ukutshintshwa, ilahleko ayikho enkulu.
Iimposiso zomnqongo wokukhanya zibangelwa ikakhulu kukusilela kwezibuko ukuba phezulu, imodyuli yokukhanya ayiqatshelwa, kunye nemposiso yezibuko CRC. Ezi mpazamo zinxulumene necala lesixhobo, imodyuli yokukhanya ngokwayo, kunye nomgangatho wekhonkco, ngakumbi impazamo kunye nokusilela kwi-UP. Misela indawo yesiphoso kwiteknoloji yesoftware. Abanye baseyingxaki yeklasi yokulungelelanisa. Akukho ngxaki phakathi kwamaqela amabini, kodwa akukho kulungiswa kunye nokulungelelaniswa phakathi kwabo, okwenza kube nzima ukusebenzisana. Le meko iseninzi, ngoko ke izixhobo ezininzi zenethiwekhi ziya kunika uhlengahlengiso. Uluhlu lwemodyuli ye-optical lufuna ukuba abathengi basebenzise iimodyuli zabo ezilungelelanisiweyo ukuze baqinisekise ukufumaneka okuzinzile.Ukuba kukho impazamo, eyona ndlela ilungileyo isekho uvavanyo lokujikeleza, ukutshintsha ikhonkco yefiber optical, imodyuli yokutshintsha, i-port yokutshintsha, ngokusebenzisa olu chungechunge lweemvavanyo ukuqinisekisa. nokuba yingxaki yemodyuli yokukhanya, okanye ikhonkco okanye ingxaki yesixhobo sezibuko, ngethamsanqa, ngokubanzi olu hlobo lwempazamo lwenzeka luqinisekile ngokwentelekiso, kunzima ukujongana nolo hlobo lwempazamo ayilungiswanga.Umzekelo, ukuba kukho CRC ipakethe engalunganga kwizibuko, imodyuli yokukhanya izakukhutshwa ngokuthe ngqo kwaye endaweni yayo ifakwe entsha. I-fault phenomenon iya kunyamalala, kwaye ke imodyuli ye-optical yasekuqaleni iya kutshintshwa kwaye iphoso ayiyi kuphinda iphindwe, okwenza kube nzima ukugweba ukuba yingxaki yemodyuli ye-optical okanye cha. Le meko idla ngokudibana ekusebenziseni okusebenzayo, okwenza kube nzima ukugweba.
Indlela yokunciphisa izinga lokungaphumeleli kweemodyuli zokukhanya? Okokuqala, inika ingqalelo ekhethekileyo kumthombo, i-bandwidth ephezulu yemodyuli yokukhanya musa ukutsibela emarikeni, ukwenza iimvavanyo ezigcweleyo, kwaye imodyuli ifuna izixhobo ezifanelekileyo, ziqonde ezi ndlela zobuchule nazo kufuneka zigqibelele ukuqola, imodyuli entsha. ukuya emarikeni, hayi nje ukufuna isantya esiphezulu, izixhobo zothungelwano ngoku zixhasa amazibuko amaninzi, hayi i-400 g, ezidityaniswe ezine 100 g nazo zinokuhlangabezana neemfuno. iimodyuli. Ababoneleli bezixhobo zeNethiwekhi kunye nabathengi beziko ledatha kufuneka balumke ekuqalisweni kweemodyuli ze-high-speed optical, bandise uvavanyo olungqongqo lweemodyuli ze-high-speed optical, kunye nokucoca ngokuqinisekileyo iimveliso ezineziphene kumgangatho.Namhlanje, ukhuphiswano lwemarike yeemodyuli ze-high-speed optical ubukhali.Bonke banethemba lokuthatha amathuba kwiimodyuli ezintsha zesantya esiphezulu, kodwa umgangatho kunye nexabiso azilingani. Oku kufuna abathengisi bezixhobo zenethiwekhi kunye nabathengi beziko ledatha ukuba bandise iinzame zabo zovavanyo. Inqanaba eliphezulu lemodyuli, ngakumbi ubunzima bokuqinisekisa.Okwesithathu, imodyuli ye-optical ngokwenene iyisixhobo esinomlinganiselo ophezulu wokudibanisa. Umzila wefiber oveziweyo kunye namacandelo angaphakathi athambileyo. Xa uyisebenzisa, kufuneka iphathwe ngobumnene, ngeeglavu ezicocekileyo ukuphepha ukuwela eluthulini, oluya kunciphisa kwakhona Sebenzisa izinga lokungaphumeleli, imodyuli ye-optical engasetyenziswanga kufuneka ixhotywe nge-fiber cap kwaye ifakwe kwisikhwama. ngaphantsi kangangoko kunokwenzeka, njenge-100 g yemodyuli yokukhanya esetyenziswa kwimeko yokusondela kumda wesantya kunye nexesha elide, imodyuli yokukhanya kwemitha engama-200, kwaye kufuneka isetyenziswe kwi-200 - umgama weemitha, la maxabiso umda. Ukusebenzisa inkunkuma yemodyuli ye-optical kukhulu, kufana nabantu, abantu basebenza kwigumbi lokupholisa umoya le-24 ~ 26 degrees, ukusebenza kakuhle kuphezulu, kubushushu obuphezulu be-35 degrees ngaphandle kokusingqongileyo, ingqwalasela ayikwazi ukugxila ixesha elide. ixesha, ukusebenza kakuhle liphantsi kakhulu, ngaphezu degrees 40, abantu beza ubushushu kwakhona indlela yokusebenza. Ukubonelela ngendawo ekhululekileyo yemodyuli ye-optical inokwandisa ngokufanelekileyo ubomi benkonzo yemodyuli ye-optical.
Ngokukhula kwedatha enkulu, imfuno ye-bandwidth yamaziko edatha iya phezulu kwaye iphezulu, kwaye ukuqaliswa kweemodyuli ze-optical ezikhawulezayo ziye zaba yindlela yodwa yokulawula umgangatho.Ukuba iimodyuli ezintsha zesantya esiphezulu zibethe udonga rhoqo. kwimarike, baya kupheliswa. Ngokuqinisekileyo, nayiphi na iteknoloji entsha inenkqubo evuthiweyo, imodyuli ye-high-speed optical ayikho enye into, idinga ukuqhubeka nokutsha kwezobuchwepheshe, ukuxazulula iingxaki ezahlukeneyo, ukuphucula umgangatho wemodyuli, ukunciphisa amathuba okusilela. Imodyuli yokukhanya kwesantya esiphezulu yinjini yenzuzo yabavelisi bemodyuli, kwaye yeyona ndawo iphambili kubavelisi bemodyuli kwii-dynasties ezidlulileyo.
