Kubona Iburyo 40G QSFP + Umuyoboro wa Breakout

Waba uri ku isoko rya40G QSFP + insinga zacitseariko ntuzi neza amahitamo akubereye?Hamwe namahitamo menshi hanze, birashobora kuba birenze kumenya imwe muribyiza kubikoresho byawe bikenera.Muri iyi nyandiko ya blog, tuzareba itandukaniro riri hagati ya fibre optique, guhuza umugozi wumuringa (DAC), hamwe na optique ya optique (AOC) kugirango igufashe gufata icyemezo kiboneye.

Mugihe cyo guhuza ibikoresho byurusobe QSFP + ibyambu kugirango ugere kuri 40G igipimo cyamakuru ya Ethernet, hari amahitamo abiri yingenzi.Buri mahitamo afite ibyiza byayo na caveats bigomba kwitabwaho.Uburyo bwatoranijwe bwatoranijwe bizaterwa nibintu nkigiciro, intera yoherejwe, guhinduka kwimuka nimpinduka, hamwe nu mwanya wa rack.

Ikintu cya mbere ugomba gusuzuma ni intera ihuza intera.Ukurikije intera, amahitamo amwe ntashobora kuba bishoboka.Kurugero, intera yoherejwe ya kabili ya DAC igarukira kuri 10m, ikwiriye cyane guhuza intera ngufi.Kurundi ruhande, umugozi wa AOC ufite uburyo bwo kohereza bugera kuri 150m, utanga uburyo bworoshye bwo gukora intera ndende.Nyamara, uko intera igenda iba ndende, ni ngombwa gusuzuma akamaro ko gushyiramo insinga hamwe na modul zashyizwe kumpera yumurongo muremure cyangwa inzira yo munsi.

Mugihe uhisemo neza 40G QSFP + yamenetse kubikoresho byurusobe, ikiguzi nikintu cyingenzi ugomba gusuzuma.Umugozi wa DAC muri rusange nuburyo buhenze cyane, bigatuma uhitamo gukundwa guhuza intera ngufi kuri bije.Kuruhande rwa fibre optique, kurundi ruhande, ikunda kuba ihenze ariko itanga ihinduka ryinshi nintera ndende.Igiciro cyinsinga za AOC hari aho kiri hagati, bigatuma habaho ubwumvikane bwiza hagati ya DAC na fibre optique.

Mugihe uhisemo insinga za 40G QSFP + zacitse, ugomba kandi gutekereza kumwanya wicyambu hamwe numwanya uhari wa rack.Kurugero, insinga za DAC muri rusange ziroroshye guhinduka kandi byoroshye gucunga ahantu hafunganye, bigatuma biba byiza guhuza mumurongo umwe.Kuruhande rwa fibre optique, kurundi ruhande, bisaba kwitonda neza kandi birashobora kuba byiza cyane kubirometero birebire hamwe nubushakashatsi buhoraho.

Muncamake, iburyo bwa 40G QSFP + yamenetse kubikoresho byurusobe biterwa nibintu bitandukanye, harimo ikiguzi, intera yoherejwe, guhinduka kwimuka nigihe kizaza, icyambu, hamwe nu mwanya wa rack.Mugusobanukirwa itandukaniro riri hagati ya fibre optique, guhuza umugozi wumuringa (DAC), hamwe numuyoboro wa optique (AOC), urashobora gufata ibyemezo byuzuye kubyo urusobe rwawe rukeneye.Waba ushyira imbere ikiguzi-cyiza, guhinduka cyangwa guhuza kure, hari igisubizo gihuye neza nibyo usabwa.
