Okwangoku, uninzi lwabasebenzisi bendawo yokuhlala kunye nabasebenzisi bedatha bafumana i-QSFP + kwi-SFP + iskipting ye-SPP + yokuphucula inethiwekhi ekhoyo ye-10G kwi-40G yenethiwekhi ngokufanelekileyo. Oku kuma-40g ukuya kwi-10G ye-10G Portmetmerment ye-Portmermen inokwenza ukusetyenziswa ngokupheleleyo kwezixhobo zenethiwekhi ekhoyo, abasebenzisi bancedisi bonga iindleko, kunye nokwenza lula ubumbeko lwenethiwekhi. Ke indlela yokufezekisa i-40g ukuya kwi-10g yosulelo? Eli nqaku liza kwabelana ngezikim ezintathu zokwahlulahlulahlulahlulahlula-hlula i-40g ukuya kwi-10g yosulelo.
Ithini i-port?
Ukuqhekeka Yenza unxibelelwano phakathi kwezixhobo zenethiwekhi kunye nezibuko ezahlukeneyo, ngelixa usebenzisa ngokupheleleyo i-bandwidth.
Imodi yokwahlulahlula kwizixhobo zenethiwekhi (ukutshintsha, ii-routers, kunye neeseva) zivula iindlela ezintsha zokusebenza kwinethiwekhi ukuze ziqhubeke nesantya se-bandwidth yebango. Ngokongeza izibuko elinesantya eziphezulu ezixhasa ukuqhubela phambili, abaqhubi bonyusa ubuso bezibuko le-Wibplati kunye nokwenza amandla ukuphuculwa kwenqanaba ledatha eliphezulu.
Amanyathelo okhuseleko lokwahlula i-40g ukuya kwi-10G yezibuko
Uninzi lweenkonkxa kwiNkxaso-mali yeMarike ye-Port. Ungajonga ukuba ngaba isixhobo sakho sixhasa i-port ikhutshiwe ngokubhekisa kwincwadana yemveliso yokutshintsha okanye ukucela umthengisi. Qaphela ukuba kumatyala athile, atshintsha amazibuko. Umzekelo, xa i-switch isebenza njengeSpecing yegqabi, ezinye izibuko alixhasi i-port iqhekeza; Ukuba izibuko lokutshintsha lisebenza njengezibuko le-stack, izibuko alinakuqhekeka.
Xa hlula izibuko le-GBB / ezi-40 ze-GBT line-4 x 10, qinisekisa ukuba izibuko liqhuba i-40 GBB / le-GBIG / SIRY ngokuzenzekelayo kwaye akukho misebenzi ye-L2 / L3 yenziwe. Qaphela ukuba ngeli xesha le nkqubo, amachweba ayaqhubeka ukubaleka ade afike kwinkqubo. Ke ngoko, emva kokuqhekeza izibuko eli-40 gbit line-4 x 10 le-GBB / S usebenzisa umyalelo we-CLI, qalisa ifowuni ukwenza umyalelo enze ukusebenza.
I-QSFP + kwi-sfp + iskimu sekhampasi
Okwangoku, i-QSFP + ukuya kwizikim zoqhagamshelo + ze-SFP ikakhulu zibandakanya oku kulandelayo:
I-QSFP + ukuya kwi-4 * sfp + i-dac / dac yekhephu
Nokuba ukhetha i-qsfp + i-qsfp + kwi-4 * i-10G sfp + i-dac copper core rible okanye i-40g qsfp + kwintambo ye-DAC ne-AOC ye-AOC kunye ne-AOC iyafana ngendlela kunye ne-AOC. Njengoko kubonisiwe kumzobo ongezantsi, isiphelo esinye sentambo ye-DAC kunye ne-AOC SHLE ye-40g qsfp + i-chanector, kwaye esinye isiphelo singama-10g sfp + isinxibelelanisi. Iplagi + ze-QSFP + ngqo kwi-QSFP + i-qsfp + i-switch kwaye ineendlela ezine ezifanayo ze-bidireals, nganye nganye esebenza kwi-10bbpps. Kuba i-dac ephezulu ye-dac yesantya esiphezulu Sebenzisa u-Copper kunye ne-AOC esebenzayo Sebenzisa i-fiber, ikwaxhasa imigama yothumelo eyahlukileyo. Ngokwesiqhelo, i-dac ephezulu yesantya esiphezulu inomgama omfutshane wothumelo. Lo ngowona mahluko ngokucacileyo phakathi kwezi zimbini.
Kwi-40g ukuya kwi-10G hlula uqhagamshelo, ungasebenzisa i-40G qsfp + ukuya kwi-4 * i-10G SFP + Intambo yoqhagamshelo lwe-SCHIC ukuze iqhagamshele kwiimodyuli ezongezelelweyo, ezongeziweyo zenethiwekhi kunye nokwenza lula inkqubo yonxibelelwano. Nangona kunjalo, umgama odluliselwa kolu nxibelelwano ulinganiselwe (i-DAC≤10m, AOC≤100m). Ke ngoko, i-dac ngqo ye-DAC okanye i-AOC ilungele ngakumbi ukudibanisa iKhabhinethi okanye kwiikhabhathi ezimbini ezikufuphi.
I-40g qsfp + ukuya kwi-4 * LC Dupplex AOC ye-AOC I-Cable Ext
I-40G qsfp + ukuya kwi-4 * LC Dupplex AOC Intambo eSebenzayo luhlobo olukhethekileyo lwentambo ye-AOC esebenzayo kwi-qsfp + i-qplex enye ye-LC kunye ne-LC eyahlukeneyo ye-LC kunye ne-LC eyahlukeneyo ye-LC kunye ne-LC eyahlukeneyo ye-LC kunye ne-LC eyahlukeneyo ye-LC kunye ne-LC eyahlukeneyo ye-LC kunye ne-LC eyahlukileyo ye-LC kunye ne-LC eyahlukeneyo ye-LC kunye ne-LC eyahlukeneyo ye-LC kunye ne-LC eyahlukeneyo. Ukuba uceba ukusebenzisa i-40G ukuya kwi-10G yentambo, ufuna iimodyuli ze-SFP + ze-SFP +, oko kukuthi, i-QSFP + intambo ye-40G qsfp + kufuneka ifakwe kwimodyuli ye-SFP ye-SFP ye-SFP ye-SFP + ye-SFP + ye-SFP. Kuba uninzi lwezixhobo zihambelana ne-LC incokoce, le ndlela yonxibelelwano inokuhlangabezana kakuhle neemfuno zabasebenzisi abaninzi.
I-MTP-4 * I-LC yesebe le-fiber fiber jumper
Njengoko kubonisiwe kula manani alandelayo, isiphelo esinye se-MTP-4 * I-LC isebe le-8-Couper ye-MTP ye-MTP ye-40G qppers, kwaye esinye isiphelo sineemodyuli ezine. Umgca ngamnye udlulisela idatha ngenqanaba le-10Gbps ukugqibezela i-40g ukuya kwi-10g yosulelo. Esi sisombululo sonxibelelwano silungele uthungelwano lwe-40g. I-MTP-4 * I-LC I-LC I-ECMERS inokuthi ixhase usulelo lwedatha yomgama omde xa kuthelekiswa ne-DAC okanye i-AOC Ringqa yoQhagamshelo. Kuba uninzi lwezixhobo zihambelana ne-LC ye-LC, i-MTP-4 * I-LC yeSebe leSikimu soqhagamshelo olunokubonelela abasebenzisi ngeskimu esiguqulwe kakhulu.
Ukuqhekeza i-40g kwi-4 * 10G kwithuI-Mylling Packer Plecker Plecker ML-NPB-3210 + ?
Sebenzisa umzekelo: Qaphela: ukwenza umsebenzi wokuqhawuka kwe-Port Part0g kumgca wokuyalela, kufuneka uqalise ifowuni
Ukufaka imowudi yolungiselelo lwe-CLI, Ngena kwifowuni nge-serial port okanye i-ssh telnet. Baleka "yenza---Qwalasela i-terminal---Isinxibelelanisi se-CE0---Isantya se-40000---uphukela ngaphandle"Imiyalelo ngokulandelelana ukuze ikwazi ukwenza umsebenzi we-CAT. Okokugqibela, qala kwakhona ifowuni njengoko ifihliwe. Emva kokuqalisa kwakhona, isixhobo sinokusetyenziswa ngokuqhelekileyo.
Emva kokuba ifowuni iqalisiwe, i-40G Port CEPMUK i-4 * I-10G Prits CEP0.0, CE0.1, CE0.2. Ezi zibuko ziqwalaselwe ngokwahlukeneyo njengamazibuko ali-10.
UMZEKELISO WENKQUBO: Kukwenza umsebenzi wokupheliswa kwezibuko ezingama-40g kumgca wokuyalela, kwaye uqhekeze i-40g port ibe ngamachweba amane ama-10g, onokuthi aqwalaselwe ngokwahlukeneyo njengezinye izibuko le-10g.
Izinto ezibekwayo kunye nezinto ezingalunganga
IINGXAKI ZOKUXELISA:
● Ukuxinana okuphezulu. Umzekelo, ukutshitshisa i-chad ye-000 ye-000 ye-chadd ye-000 ye-chadd kunokubonelela ngobukhulu bokutshintsha kwe-switne-lanerlink. Ngenxa yoko izuze inani elifanayo lonxibelelwano kusetyenziswa inani elincinci lemidlalo.
● Ukufikelela kwi-intanethi yesantya esezantsi. Umzekelo, i-QSFP-4X10G-LRCEIP-s transceiver inceda ukutshintshela kwizibuko le-qsfp kuphela ukuqhagamshela i-4x 10g lr i-mesces nganye.
● Ukugcina uqoqosho. Ngenxa yesidingo esincinci sezixhobo eziqhelekileyo kubandakanya ne-chassis, amakhadi, abathengisi bemimandla, abalandeli, ...
Izinto ezingalunganga zokuqhekeka:
● Isicwangciso esiliqili sokutshintsha. Xa elinye lamazibuko kwi-trapceiver, i-AOC okanye i-DAC, ihamba imbi, ifuna ukutshintshwa yonke i-transcere okanye intambo.
● Ayisiyo njengokufihlakeleyo. Kwimisitho-tshintshela i-pinks enye, izibuko ngalinye lilungisiwe ngokwahlukeneyo. Umzekelo, isibuko esinye sinokuba li-10g, 25g, okanye i-50g kwaye singalwamkela naluphi na uhlobo lwe-transceiver, i-AOC okanye i-DAC. Izibuko le-QSFP kuphela kwimodi yokuqhubela ifuna indlela enobulumko yeqela, apho zonke izinto eziguqukayo ze-transceiver okanye intambo ziluhlobo olufanayo.
