Waqtigan xaadirka ah, inta badan iskuulada dhexe ee shirkadda 'SFPP + to SFP' si loo casriyo shabakadda 10G ee jira illaa 40G si hufan oo macquul ah si ay ula kulmaan baahida sii kordheysa ee gudbinta xawaaraha sare. Tani waa 40g ilaa 10G ee kala goynta dekada waxay sameyn kartaa si buuxda oo loogu talagalay aaladaha shabakadda ee jira, ka caawin kara isticmaaleyaasha inay keydiyaan kharashyada, oo ay fududeeyaan qaabeynta shabakada. Marka sida loo gaaro 40g ilaa 10G? Qodobkaani wuxuu la wadaagi doonaa seddex qorshayaal kala go 'si ay kaaga caawiso inaad ku guuleysato 40g ilaa 10G ilaa 10G.
Waa maxay jabinta dekeda?
Kala go'ida waxay awood u siisaa isku xirnaanta ka dhexeysa aaladda shabakadda oo leh dekedo xawaare kaladuwan ah, halka ay si buuxda u adeegsanayaan PortWidth.
Qaabka kala-goynta ee qalabka shabakadda (beddelaadda, wadooyinka, iyo adeegayaasha) waxay u furayaan qaabab cusub oo ka shaqeeya shabakadaha shabakadaha si ay ula jaan qaadaan xawaaraha baahiyaha xarkaha. Adigoo ku daraya dekedaha xawaaraha sare ee taageeraya jabinta, hawl wadeenada ayaa kordhin kara cufnaanta dekada oo ay awood u yeeshaan kor u qaadista heerka sare ee xogta si kordhinta sare.
Taxaddarrada loogu talagalay kala-goynta 40g ilaa 10g dekedaha dekedaha
Inta badan waxay ku wareegaan kala-goynta suuqa ee suuqa. Waad ka hubin kartaa in qalabkaagu uu taageerayo kala-goynta dekedaha isagoo tixraacaya buugga badeecada ama weydiisashada alaab-qeybiyeyaasha. Xusuusnow in kiisaska qaaska ah, dekedaha wareejinta aan la kala qaybin karin. Tusaale ahaan, marka loo beddelo sida ugu beddelato sidii suuxdin caleen, qaar ka mid ah dekedaha ma taageeraan kala-goynta dekedaha; Haddii dekedda wareegga uu u adeego sidii deked kale, dekada lama kala saari karo.
Markaad kala go'day 40 Git / s deked ah Xusuusnow in inta lagu gudajiro howshan, dekeddu waxay kusii socotaa 40Gbps illaa nidaamku dib u bilaabo. Sidaa darteed, ka dib markii uu kala jaray 40 Git / S Deka Git / Gwit / s Dekadaha Git / S ee loo adeegsado Taliska CLI, dib u bilow aaladda si amarka loo dhaqan geliyo.
QSFP + In SFP + Chilins Chiption
Waqtigan xaadirka ah, QSFP + ilaa SFP + Nidaamyada Xiriirinta ee inta badan waxaa ka mid ah waxyaabaha soo socda:
QSFP + ilaa 4 * SFP + Dac / AoC Tooska Tooska Tooska ah ee Cable
Haddii aad doorato 40G QSFP + ilaa 4 * 10G SFP + Dac Perper Copper + DECPP + ilaa 4 * 10G SFP + AOC Cable Cable, xiriirku wuxuu la mid noqon doonaa sababta oo ah Dam iyo AOC-ga ayaa la mid ah qaabeynta iyo ujeedka. Sida lagu muujiyey shaxanka hoose, hal dhamaadka dhamaadka Dac iyo AOC Tooska Tooska ah waa 40G QSFP + Conner, oo dhamaadka kalena waa 10G 10G SFP + isku xirka. QSFP + waxay si toos ah ugu gashataa dekada QSFP + dekada oo leh afar kanaal oo isbarbar socda, oo mid walbana ka shaqeeya qiimayaasha ilaa 10Gbps. Maaddaama DAC-da-xawaaraha xawaaraha-sare ay isticmaalaan naxaasta naxaasta iyo AOC FEDE FEDER FIPLE, waxay sidoo kale taageeraan masaafado kaladuwan oo kala-gudbinta ah. Caadi ahaan, fiilooyinka xawaaraha sare ee DAC waxay leeyihiin masaafado masaafado gaagaaban. Tani waa farqiga ugu muuqda ee u dhexeeya labada.
40G illaa 10G oo isku xirka ah, waxaad isticmaali kartaa 40G QSFP + ilaa 4 * 10G SFP + fiilo toos ah si aad ugu xirtid beddelka models-ka oo aan iibsan kharashaadka indhaha oo dheeraad ah, oo fududeynaya nidaamka isku xirka. Si kastaba ha noqotee, masaafada faafinta ee isku xirkan waa mid xadidan (dac≤10m, aoc≤100m). Sidaa darteed, xarkaha tooska ah ee DAC ama AOC Cable-ka ayaa aad ugu habboon isku xirka golaha wasiirrada ama laba armaajooyinka ku xiga.
40G QSFP + ilaa 4 * LC Duflex aoc laanta astaanta firfircoon
40G QSFP + ilaa 4 * LC Duflex aoc-ka laanta firfircoon waa nooc gaar ah oo fiilo firfircoon oo leh xaashida QSFP + Qashinka iyo afarta lugta ee LC Duax-ka ee kala duwan. Haddii aad qorsheynaysid inaad 40G u isticmaasho 10g fiilo firfircoon, waxaad u baahan tahay afar qaybood oo sfp + ah, taasi waa, interface-ka ah ee QSFP + ilaa 4 * LC Duffal ee aaladda, iyo interface-ka LC-ka waa in la galiyaa 10G sfp + ee aaladda. Maaddaama aaladaha badankood ay la jaan qaadayaan is-dhexgalka LC, habkan isku xirkaani wuxuu si fiican u buuxin karaa baahiyaha isticmaaleyaasha badankood.
Mtp-4
Sida lagu muujiyey tirada soo socota, hal dhamaadka MTP-4 * LC stack jumper waa 8-core sperface-ka 8-core ah oo ah modules + oo ah qaybo kale oo labajibbaarane ah oo lagu xirayo afar 10g sfp + Xariiq kasta wuxuu ku gudbiyaa xogta sicirka 10Gbps si loo dhammaystiro 40G ilaa 10G ilaa 10G ilaa 10G ilaa 10G. Xalka xiriirkan wuxuu ku habboon yahay 40G shabakadaha cufnaanta sare. MTP-4 * LC GRATERS RAMPERS waxay taageeri karaan gudbinta xogta masaafada dheer marka loo barbar dhigo Dam ama AoC Tooska Tooska Tooska ah. Maaddaama aaladaha badankood ay la jaan qaadayaan is-dhexgalka LC-ga, Mtp-4
Sida loo jajabiyo 40g 4g 4 * 10g onXirmooyinka shabakada ee shabakadda ee Milker ML-NPB-3210 + ?
Adeegso Tusaale: Xusuusin: Si aad u awood u yeelato shaqada jebinta dekada 40G ee khadka taliska, u baahan tahay dib u bilaw aaladda
Si aad u gashid qaabka qaabeynta CLI, gal aaladda iyada oo loo marayo meesha dekada taxanaha ama ssh telnet. Maamulo "karsiin---Ku habeeyso Terminal---Interface CE0---Xawaare 40000---joojind"Amarada isku xigxiga si ay u suurtogeliyaan shaqada jabinta dekeda ee CE0. Ugu dambeyntiina, dib u bilaw aaladda sida lagu dhaliyay. Dib-u-bilaabashada ka dib, aaladda ayaa si caadi ah loo isticmaali karaa.
Ka dib markii aaladda dib loo bilaabo, 'dekeda' CE0 'wuxuu u burburay 4 * 10ge dekedaha CE0.0, CE0.1, CE0.2, iyo CE0.3. Dekedahan ayaa si gooni gooni ah loogu habeeyay sidii dekedaha kale ee 10da ah.
Tusaale Tusaalaha: Waa in loo oggolaado shaqada jebinta ee dekada 40G ee khadka tooska ah, oo ku burbura afarta dekedaha oo dhan, kaas oo si gooni gooni ah loogu habeyn karo sida dekedaha kale ee 10G ah.
Faa'iidooyinka kala goynta iyo faa'iido darrada
Faa'iidooyinka jabinta:
● Cufnaanta sare. Tusaale ahaan, wareejinta 36-dekeda QDD ee QDD waxay noqon kartaa saddex-geesood cufnaanta loo beddelo dekedaha hal-haad-ka-leexashada. Markaa waxay gaarayaan tiro isku mid ah isku xirnaanta iyadoo la adeegsanayo tiro yar oo beddelaad ah.
● Helitaanka is-dhexgalka xawaaraha hoose. Tusaale ahaan, QSFP-4x10G-Lr-Lr-ka waxay awood u siineysaa bedelka oo keliya dekedaha QSFP oo keliya si ay ugu xiraan 4x 10g LR Interfaces kasta dekedda.
● Kaabayaasha dhaqaalaha. Sababo la xiriira baahi yar oo loogu talagalay qalabka caanka ah oo ay ka mid yihiin chassis, kaararka, alaab-qeybiyeyaasha awooda, taageerayaasha, ...
Faa'iido darrooyinka burburka:
Costs Istaraatiijiyad beddelaad ah oo adag. Marka mid ka mid ah dekedaha ku yaal Transcopiver-ka jabinta, AOC ama DAC, uu xun yahay, waxay u baahan tahay beddelaadda guud ama fiilada.
● Maaha sidii loo isticmaali karo. Iyada oo lagu beddelo hal-haad-haad-kaan, deked kasta ayaa si gaar ah loo habeeyay. Tusaale ahaan, deked gaar ah ayaa noqon karta 10g, 25g, ama 50g oo ay aqbali karaan nooc kasta oo transcepy, aoC ama Dac. Deked kaliya ee QSFP ah oo ku jirta qaab-jabinta ayaa u baahan qaab xikmad leh, halkaas oo dhammaan isweydaarsiga transcor-ka ama fiilada ay yihiin isla noocaas.
