Waqtigan xaadirka ah, inta badan shabakadaha ganacsiga iyo isticmaalayaasha xarumaha xogta waxay qaataan QSFP + ilaa SFP+ nidaamka kala qaybinta dekeda si loogu cusboonaysiiyo shabakada 10G ee jirta ilaa shabakada 40G si hufan oo xasiloon si loo daboolo baahida sii kordheysa ee gudbinta xawaaraha sare. Qorshahan kala qaybinta dekeda 40G ilaa 10G wuxuu si buuxda u isticmaali karaa aaladaha shabakadaha jira, wuxuu ka caawin karaa isticmaalayaasha inay badbaadiyaan kharashaadka, oo ay fududeeyaan qaabaynta shabakada. Haddaba sidee lagu gaari karaa gudbinta 40G ilaa 10G? Maqaalkani wuxuu wadaagi doonaa saddex qorshe oo kala qaybsan si ay kaaga caawiyaan inaad gaarto 40G ilaa 10G.
Waa maxay Burburka Dekeddu?
Burburinta waxay awood u siinaysaa isku xidhka aaladaha shabakadda ee leh dekedo xawliyeed oo kala duwan, iyadoo si buuxda looga faa'iidaysanayo xawaaraha dekedda.
Habka jabinta ee qalabka shabakadaha (switchs, routers, and servers) ayaa u furaya habab cusub oo loogu talagalay hawl wadeenada shabakada si ay ula socdaan xawaaraha baahida bandwidth. Marka lagu daro dekedo xawaarihiisu sarreeyo oo taageera jabinta, hawl-wadeenadu waxay kordhin karaan cufnaanta dekedda waxayna awood u siin karaan kor u qaadida qiimaha xogta sare si kor loogu qaado.
Taxadir ku saabsan kala qaybinta 40G ilaa 10G Ports Breakout
Inta badan furayaasha suuqa ayaa taageera kala qaybsanaanta dekedda. Waxaad hubin kartaa in qalabkaagu taageerayo kala qaybinta dekeda adoo tixraacaya buug-gacmeedka badeecada ama waydiisa alaab-qeybiyaha. Ogow in xaaladaha gaarka ah qaarkood, dekedaha beddelka aan la kala qaybin karin. Tusaale ahaan, marka daaranuhu u dhaqmo sidii beddelka caleenta, qaar ka mid ah dekedeheedu ma taageeraan kala qaybinta dekedda; Haddii deked beddelashadu u adeegto sidii deked isku xidhan, dekeddu lama kala qaybin karo.
Markaad u kala qaybinayso 40 Gbit/s dekedo 4 x 10 Gbit/s dekedood, hubi in dekeddu ku socoto 40 Gbit/s si caadi ah oo aan hawlo kale oo L2/L3 ah la shaqayn. Ogsoonow in inta lagu jiro nidaamkan, dekeddu waxay sii wadaa inay ku shaqeyso 40Gbps ilaa nidaamku dib u bilaabo. Sidaa darteed, ka dib markaad u kala qaybiso 40 Gbit / s dekedaha 4 x 10 Gbit / s dekedaha adoo isticmaalaya amarka CLI, dib u bilaw qalabka si aad amarku u dhaqan gasho.
QSFP+ ilaa SFP+ Qorshaha Cabitaanka
Waqtigan xaadirka ah, QSFP+ ilaa SFP+ qorshayaasha isku xirka inta badan waxaa ka mid ah kuwan:
QSFP+ ilaa 4*SFP+ DAC/AOC Qorshaha Isku xirka Xadhkaha Tooska ah
Haddii aad dooratid 40G QSFP + ilaa 4 * 10G SFP + DAC copper core cable-xawaaraha sare ama 40G QSFP + ilaa 4 * 10G SFP + AOC fiilada firfircoon, xiriirku wuxuu noqon doonaa isku mid sababtoo ah DAC iyo AOC cable waxay la mid yihiin naqshadeynta iyo ujeedada. Sida ku cad shaxanka hoose, hal dhamaadka DAC iyo fiilada tooska ah ee AOC waa 40G QSFP + isku xidhaha, iyo dhamaadka kale waa afar kala duwan oo ah 10G SFP +. Xidhiidhiyaha QSFP+ wuxuu si toos ah ugu xidhaa dekedda QSFP+ ee shideeyaha wuxuuna leeyahay afar kanaal oo isbarbar socda, mid walbana wuxuu ku shaqeeyaa ilaa 10Gbps. Maadaama fiilooyinka xawaaraha sare ee DAC ay isticmaalaan naxaas iyo AOC fiilooyinka firfircoon waxay isticmaalaan fiber, waxay sidoo kale taageeraan masaafada kala duwan ee gudbinta. Caadi ahaan, fiilooyinka xawaaraha sare ee DAC waxay leeyihiin masaafo gudbin gaaban. Tani waa farqiga ugu cad ee u dhexeeya labada.
Isku xirka 40G ilaa 10G kala qaybsanaanta, waxaad isticmaali kartaa 40G QSFP + ilaa 4 * 10G SFP + fiilada tooska ah si aad ugu xirto furaha adiga oo aan soo iibsan qaybo dheeri ah oo indhaha ah, badbaadinta kharashyada shabakada iyo fududaynta habka isku xirka. Si kastaba ha ahaatee, masaafada gudbinta ee xidhiidhkan ayaa xaddidan (DAC≤10m, AOC≤100m). Sidaa darteed, fiilada tooska ah ee DAC ama AOC ayaa aad ugu habboon isku xirka golaha wasiirada ama labada armaajo ee isku dhow.
40G QSFP+ ilaa 4*LC Duplex AOC Branch Cable Firfircoon
40G QSFP + ilaa 4 * LC duplex AOC laanta firfircoon ee fiilada firfircoon waa nooc gaar ah oo fiilada firfircoon ee AOC oo leh xiriiriye QSFP+ ah oo ku yaal hal daraf iyo afar jumpers LC duplex ah oo kale. Haddii aad qorsheyneyso inaad isticmaasho 40G ilaa 10G fiilo firfircoon, waxaad u baahan tahay afar qaybood oo SFP + ah, taas oo ah, QSFP + interface ee 40G QSFP + ilaa 4 * LC duplex fiilada firfircoon ayaa si toos ah loo gelin karaa dekedda 40G ee qalabka, iyo Interface LC waa in la geliyo 10G SFP+ moduleka indhaha ee u dhigma ee qalabka. Maadaama aaladaha intooda badani ay ku habboon yihiin is-dhexgalka LC, qaabkan isku xirka wuxuu si fiican u dabooli karaa baahida isticmaalayaasha badankood.
MTP-4* Laanta LC Fiber Jumper
Sida ku cad shaxanka soo socda, hal dhamaadka MTP-4 * LC jumper laanta waa 8-core interface MTP oo loogu talagalay isku xirka 40G QSFP + modules indhaha, iyo dhamaadka kale waa afar duplex LC jumpers oo ku xiran afar 10G SFP + modules indhaha. . Xariiq kastaa waxa uu ku gudbiyaa xogta xadiga 10Gbps si loo dhamaystiro gudbinta 40G ilaa 10G. Xalka isku xirka wuxuu ku habboon yahay shabakadaha cufan ee 40G. MTP-4* Laan boodayaasha LC waxay taageeri karaan gudbinta xogta masaafo dheer marka loo eego fiilooyinka tooska ah ee DAC ama AOC. Maadaama aaladaha badankoodu ay ku habboon yihiin is-dhex-galka LC, MTP-4* LC nidaamka isku xirka laanta jumper waxay siin kartaa isticmaalayaasha nidaam fiilo dabacsanaan badan.

Isticmaal tusaale: Xusuusin: Si aad awood ugu yeelatid shaqada goynta ee dekedda 40G ee khadka taliska, waxaad u baahan tahay inaad dib u bilowdo qalabka
Si aad u gashid qaabka qaabeynta CLI, ka gal aaladda marinka taxanaha ah ama SSH Telnet. Orod "awood---habayn terminal---interface ce0---xawaaraha 40000---dillaacid” waxay amar ku bixisaa si isku xigxig ah si ay awood ugu siiso shaqada jabinta dekedda CE0. Ugu dambeyntii, dib u billow qalabka sida lagugu dhiirigeliyay. Ka dib dib u bilaabashada, qalabka si caadi ah ayaa loo isticmaali karaa.
Ka dib markii aaladda dib loo bilaabo, 40G dekedda CE0 ayaa u kala jabtay 4 * 10GE dekedaha CE0.0, CE0.1, CE0.2, iyo CE0.3. Dekadahaan waxaa loo habeeyey si gooni ah sida 10GE dekedood oo kale.
Tusaale ahaan barnaamijka: waa in la suurtageliyo shaqada goynta ee dekedda 40G ee khadka taliska, iyo in la jebiyo dekedda 40G afar dekedood oo 10G ah, kuwaas oo si gaar ah loo habayn karo sida dekedaha kale ee 10G.
Jebinta Faa'iidooyinka iyo Khasaaraha
Faa'iidooyinka dillaacista:
● Cufnaanta sare. Tusaale ahaan, 36-dekedood ee QDD-dareeshka ayaa bixin kara saddex-laab cufnaanta furaha leh dekedo hoose oo hal haad ah. Markaa lagu gaadho tiro isku mid ah isku xidhka iyadoo la isticmaalayo tiro yar oo furayaasha ah.
● Gelitaanka is dhex galka xawaaraha hooseeya. Tusaale ahaan, transceiver-ka QSFP-4X10G-LR-S wuxuu awood u siinayaa beddelka leh dekedaha QSFP oo keliya inuu ku xidho 4x 10G LR interfaces deked kasta.
● Keydka dhaqaalaha. Sababtoo ah baahi yar oo loo qabo qalabka guud oo ay ku jiraan chassis, kaarar, alaab-qeybiyeyaal koronto, taageereyaal,…
Khasaaraha dillaaca:
● Xeelado beddelaad oo aad u adag. Marka mid ka mid ah dekedaha ku yaal transceiver-ka jaban, AOC ama DAC, ay xumaato, waxay u baahan tahay beddelka transceiverka ama fiilada oo dhan.
● Ma aha sida la beddeli karo. Shidayaasha leh hal haad oo hoose, deked kasta si gaar ah ayaa loo habeeyey. Tusaale ahaan, deked shakhsi ah waxay noqon kartaa 10G, 25G, ama 50G waxayna aqbali kartaa nooc kasta oo transceiver ah, AOC ama DAC. Deked-keliya QSFP ee qaabka jabintu waxay u baahan tahay hab koox-xikmad leh, halkaas oo dhammaan is-dhexgalada transceiver ama fiilada ay isku nooc yihiin.
