Cable ea AOCvs Cable ea DAC: Ke Efe e Molemo ho Uena

1. Lik'habole tsa DAC le tsa AOC li na le Joang?
Ka bobeli DAC le AOC ke litharollo tse tloaelehileng tsa li-cabling bakeng sa marang-rang a data 'me hangata li sebelisetsoa ho hokahanya ka lebelo le phahameng, ho tšepahala ho phahameng le ho fetisoa ho hlokehang ke litsi tsa data, lik'homphieutha tse sebetsang hantle, le lisebelisoa tse kholo tsa polokelo.Liphello tsa tsona ka bobeli li na le likopano tsa cable tse nang le li-transceivers tse felisitsoeng ke feme, tse hokahaneng le likoung tse tsitsitseng feela.Ntle ho moo, lithapo tsa DAC le AOC li ka etsoa ka bolelele bo fapaneng ho tšehetsa litekanyetso tse fapaneng tsa phetisetso ea data, joalo ka 10G SFP DAC/AOC cable, 25G AOC cable, 40G DAC cable, le 100G AOC cable.

2. Melemo le Mathata a Cable ea DAC

Melemo ea Direct Attach Copper Cable

E na le litšenyehelo tse ngata - Ka kakaretso, theko ea likhoele tsa koporo e tlase haholo ho feta ea likhoele tsa optical.Litsenyehelo tsa likhoele tsa koporo tse sa sebetseng li theko e tlase ka makhetlo a 2 ho isa ho a 5 ho feta likhoele tsa fiber tse bolelele bo lekanang.Ka hona, ts'ebeliso ea lithapo tsa lebelo le phahameng le eona e tla fokotsa litšenyehelo tsa cabling tsa setsi sa data kaofela.

Tšebeliso ea Matla a Tlase - DAC e lebelo le phahameng (thapo e hokeletsoeng ka kotloloho) e sebelisa matla a fokolang (ts'ebeliso ea motlakase e batla e le zero) kaha likhoele tse sa sebetseng ha li hloke phepelo ea motlakase.Tšebeliso ea matla ea likhoele tse sebetsang tsa koporo hangata e ka ba 440mW.Haeba u sebelisa likhoele tsa koporo tse hokeloang ka kotloloho sebakeng sa likhoele tsa fiber tsa AOC, u ka boloka li-kilowatt tse likete tse makholo tsa matla a motlakase.

E tšoarella ho feta - E entsoe ka mokhoa oa khokahanyo o se nang seamless oa optical module le optical cable, e fokotsang litšenyehelo le ho netefatsa hore optical port ha e pepesehetse lerole le litšila tse ling.Ka hona, DAC ha e kotsing ea ho senyeha.

E 'ngoe ea likotsi tsa thapo ea DAC ke hore e boima ebile e boima ho feta li-AOC.Ntle le moo, e ka hlaseloa habonolo ke tšitiso ea motlakase le ho fokotseha ha sebaka se selelele ka lebaka la matšoao a motlakase a fetisoang lipakeng tsa mahlakore ka bobeli.

3. Melemo le Mathata a Cable ea AOC

Melemo ea AOC

Boima bo bobebe-Thapo e sebetsang ea optical e entsoe ka li-transceivers tse peli tsa optical le fiber optic patch cable, eo boima ba eona e leng kotara feela ea khoele ea koporo e tobileng, 'me bongata bo ka bang halofo ea mohala oa koporo.

Libaka tse telele - fiber ea AOC e ka fana ka phetisetso e kholoanyane le e telele ho fihla ho 100-300m ka lebaka la mocheso oa eona o betere oa tsamaiso ea likhoele tsa phaposi ea khomphutha le radius e kobehang ea thapo ea optical.

E ts'epahala ho feta - Cable e sebetsang ea Optical ha e kotsing ea ho kena-kenana le motlakase kaha fiber ea optical ke mofuta oa dielectric o ka ts'ehetsang lebala la motlakase le sa fetoheng ka har'a eona.Tekanyo e nyane ea phoso ea ts'ebetso ea phetisetso ea sehlahisoa le eona e betere, mme BER e ka fihla ho 10 ^ -15.

Melemo ea AOC

Bothata bo boholo ba likhoele tsa fiber tse sebetsang tsa AOC ke hore ke tharollo ea kopano e theko e phahameng haholo bakeng sa basebelisi ba setsi sa data se phahameng haholo.Ntle le moo, li-AOC ha li tšoarelle nako e telele haeba li sa laoloe ka nepo kaha li bobebe ebile li le mosesaane li-AOCs li bobebe haholo ebile lia tšesaane tse etsang hore li be kotsing ea ho senyeha haeba li sa sebetsoe ka nepo.

4. U sebelisa lithapo tsa AOC neng?

Leha ho le joalo, sebaka sa phetisetso lipakeng tsa ToRs le li-switches tsa mantlha hangata se ka tlase ho 100m, moo li-circuits tse kopaneng li tsamaisoang ka bongata.Ka hona, thapo e sebetsang ea optical ke tharollo e betere ea ho hokahanya data ka lebaka la boleng ba eona bo bobebe, bophara ba terata e nyane, le tlhokomelo e laolehang ea cabling.Kaha setsi sa data se na le litlhaloso tse tiileng mabapi le phetisetso ea matšoao, thapo e sebetsang ea optical e molemo ho feta thapo ea DAC ea mafahla ka ponts'o ea ponts'o le moralo oa coupling oa optical, e fokotsang liphoso haholo ts'ebetsong ea matšoao.Ho feta moo, lets'oao le phahameng la EMI le sebetsoa ka har'a li-module tsa optical plugable, thapo ea fiber ea AOC e na le ts'ebetso e ntle ea EMI ho feta thapo ea DAC.Ntle ho pelaelo, thapo ea AOC ke khetho ea hau ea pele khokahanong lipakeng tsa li-switches le li-switches ka nako e khuts'oane kapa e mahareng.

5. U Sebelisa Lithapo tsa DAC Neng?

Ho latela meaho ea masela e phatlalalitsoeng ke Facebook, seva le li-switches tsa Top-of-Rack (ToR) li etsa karolo ea mantlha ea setsi sa data.Ka kakaretso, sebaka se pakeng tsa ToR le seva NIC(Network Interface Card) se ka tlase ho limithara tse 5.Boemong bona, thapo ea DAC e molemo ho feta likhoele tsa AOC mabapi le litšenyehelo, tšebeliso ea matla le phallo ea mocheso.Kahoo, DAC ke khetho e ratoang bakeng sa litsamaiso tsa khokahano ea IDC.Ntle le moo, ka linako tse ling tse ikhethang, 100G QSFP28 ho 4 * SFP28 DAC ke khokahano e 'ngoe e tobileng ho latela tlhoko e ikhethileng ea mosebelisi bakeng sa khokahano ea data.
