1. Iyini imodyuli ye-QSFP fiber optic transceiver?

- Okokuqala, kufanele siqonde, iyini i-module ye-SFP fiber optic transceiver? I-module ye-SFP fiber optic transceiver (igama eligcwele: I-Small Form-factor Pluggable), ibhekisela kumadivayisi amancane, aguquguqukayo, ashintshashintshayo enethiwekhi (ama-transceiver) angena kuma-port kuma-switch, ama-router, kanye namaseva, okuvumela amadivayisi enethiwekhi ukuthi axhumeke ngemidiya ehlukene njengezintambo ze-fiber optic noma zethusi zezinhlelo zokusebenza ezahlukahlukene, kusukela ku-Gigabit Ethernet kuya ku-Fibre Channel.

- I-module ye-transceiver ye-fiber optic ye-QSFP (Quad Small Form-factor Pluggable) iyindlela ethandwayo ye-transceiver form factor yokuxhumana ngesivinini esikhulu, esetshenziselwa ukuxhumana kwedatha okusheshayo ezikhungweni zedatha, isekela amazinga kusukela ku-10G kuya ku-400G+ ngokusebenzisa imizila emine ehambisanayo, ivumela i-bandwidth ephezulu kune-SFP ejwayelekile ngobukhulu obuncane. Izinguquko ezibalulekile zifaka phakathi i-QSFP+, QSFP28, QSFP56, kanye ne-QSFP-DD, ngayinye isekela isivinini esihlukile (40G, 100G, 200G, 400G) ngokwandisa amazinga edatha ngomzila ngamunye (10G, 25G, 50G, 100G) kanye nokusebenzisa ukuxhumana kwe-copper noma i-fiber optic.

2. Isebenza kanjani i-QSFP?

- Amamojula e-QSFP fiber optic transceiver axhuma emishinini yenethiwekhi, aguqula izimpawu zikagesi zibe izimpawu ezibonakalayo noma zethusi zokudlulisa idatha ngesivinini esikhulu, esebenza njengesixhumanisi esibalulekile sengqalasizinda yenethiwekhi edingayo.

- Amachweba e-QSFP kumaswishi asekela izinhlobo ezahlukene zemidiya:

+ I-DAC (I-Direct Attach Copper): Ibiza kancane ekuxhumaneni kwe-server-to-switch okufushane (ngokuvamile <7m).
+ AOC (Ikhebula Elisebenzayo Elibonakalayo): Isebenzisa i-fiber ekude kunethusi kodwa inezixhumi eziqinile kuzo zombili izinhlangothi.
+ Amamojula Okukhanya: Ama-transceiver axhunywayo (njenge-SR4, i-LR4, noma i-BiDi) axhuma kumakhebula ajwayelekile e-fiber optic.
