1. Yintoni imodyuli ye-QSFP fiber optic transceiver?

- Okokuqala, kufuneka siqonde, yintoni imodyuli ye-SFP fiber optic transceiver? Imodyuli ye-SFP fiber optic transceiver (igama elipheleleyo: Small Form-factor Pluggable), ibhekisa kwizixhobo ezincinci, ze-modular, ezikwaziyo ukutshintshelwa kwi-network interface (ii-transceivers) ezihambelana namazibuko kwiiswitshi, ii-routers, kunye neeseva, ezivumela izixhobo zenethiwekhi ukuba ziqhagamshele ngemidiya eyahlukeneyo efana neentambo ze-fiber optic okanye ze-copper kwizicelo ezahlukeneyo, ukusuka kwi-Gigabit Ethernet ukuya kwi-Fibre Channel.

- Imodyuli ye-QSFP (Quad Small Form-factor Pluggable) ye-fiber optic transceiver yeyona nto idumileyo ye-transceiver form factor kwinethiwekhi yesantya esiphezulu, esetyenziselwa unxibelelwano lwedatha olukhawulezayo kwiindawo zedatha, ixhasa amazinga ukusuka kwi-10G ukuya kwi-400G+ ngokusebenzisa iindlela ezine ezihambelanayo, ivumela i-bandwidth ephezulu kunee-SFP eziqhelekileyo ngobukhulu obuncinci. Utshintsho oluphambili luquka i-QSFP+, QSFP28, QSFP56, kunye ne-QSFP-DD, nganye ixhasa isantya esahlukileyo (40G, 100G, 200G, 400G) ngokunyusa amazinga edatha ngomzila ngamnye (10G, 25G, 50G, 100G) kunye nokusebenzisa uqhagamshelo lwe-copper okanye lwe-fiber optic.

2. Isebenza njani i-QSFP?

- Iimodyuli ze-QSFP fiber optic transceiver zifakelwa kwizixhobo zenethiwekhi, ziguqula imiqondiso yombane ibe yimiqondiso ye-optical okanye ye-copper yokudlulisa idatha ngesantya esiphezulu, zisebenza njengekhonkco elibalulekileyo kwiziseko zophuhliso zenethiwekhi ezifuna uncedo.

- Iiports zeQSFP kwiiswitshi zixhasa iintlobo ezahlukeneyo zemidiya:

+ I-DAC (I-Direct Attach Copper): Ixabiso eliphantsi kwiintambo zonxibelelwano ze-server-to-switch ezikude (ngesiqhelo zingaphantsi kwe-7m).
+ AOC (Intambo ye-Optical esebenzayo): Isebenzisa ifayibha kumgama omde kune-copper kodwa inezihlanganisi ezizinzileyo kuzo zombini iziphelo.
+ Iimodyuli ze-Optical: Ii-transceivers ezixhunywayo (ezifana ne-SR4, i-LR4, okanye i-BiDi) eziqhagamshela kwiintambo ze-fiber optic eziqhelekileyo.
