Incazelo
1. Iyini i-100G QSFP28 ikhebula le-AOC esebenzayo?
I-100G AOC ikhebula elibonakalayo elisebenzayo libhekisela kukhebula lokuxhumana esebenzisa amandla angaphandle ukuguqula amasignali kagesi abe amasignali optical noma amasignali optical ibe amasignali kagesi.Ama-transceivers optical kuzo zombili iziphetho zekhebula le-optical ahlinzeka ngokuguqulwa kwe-optical kanye nemisebenzi yokudlulisa optical, futhi izinga lokudlulisela lifinyelela ku-100 GB / s.
2. Iyini i-DAC ye-100G yethusi enesivinini esikhulu?
Intambo yethusi ye-100G yesivinini esiphezulu se-DAC yamukela i-conductor ene-silver plated kanye ne-foam insulated core wire, enokusebenza okuhle kakhulu kokunciphisa nokusebenza kokulibaziseka okuphansi, ukudluliswa kwesignali okunembile, futhi ingathuthukisa isivinini sokudlulisela.Kuyisixazululo sokuxhumeka kwebanga elifushane ukufaka amamojula optical.Intengo yayo iphansi kakhulu kunaleyo yamamojula afanayo optical, ngakho-ke yamukelwa kabanzi kuzinhlelo zokusebenza zokuxhumanisa amabanga amafushane.

Ukwakheka Komkhiqizo
1. Isakhiwo se-AOC sekhebula le-100G elisebenzayo
Ikhebula le-optical elisebenzayo lakhiwa ama-transceiver amabili e-fiber optical kanye ne-jumper eyodwa yekhebula optical.Yakhiwe ngama-transceivers e-fiber optical emikhawulweni yomibili kanye nezinhlobo ezahlukene ze-fiber optical OM3 kanye ne-OM4 i-multimode optical fiber.
2. Isakhiwo se-DAC se-100G se-copper esisheshayo
Izintambo zethusi ezinesivinini esikhulu zingahlukaniswa zibe izintambo zethusi ezinesivinini esiphezulu kanye nezintambo zethusi ezisebenzayo ezinesivinini esikhulu.Ikhebuli yethusi esebenzayo enesivinini esiphezulu ine-chip eyodwa yomshayeli kunekhebula lethusi elinesivinini esiphezulu."Amamojula okukhanya" kuzo zombili iziphetho ze-DAC yethusi enesivinini esikhulu awawona amamojula wangempela optical.Azinazo izingxenye futhi zingadlulisa amasignali kagesi kuphela.Ngakho-ke, i-DAC yethusi enesivinini esikhulu ishibhile kunamanye amadivaysi ajwayelekile okubona.Ngisho noma imbobo efanayo isetshenziswa njengesixhumi esibonakalayo semojula yefayibha, ikhebula le-copper elinesivinini esiphezulu lingonga izindleko futhi linciphise ukusetshenziswa kwamandla ezinhlelweni zebanga elifushane.Yingakho abantu bekhetha izintambo zethusi ezinesivinini esikhulu.I-DAC yethusi enesivinini esiphezulu, exhunywe kumaswishi noma amaseva kuzo zombili iziphetho, ivumela ukudluliswa kwebanga elifushane.
Ukwahlukanisa
