Isebenza kanjani i-Optical fibre transceiver module SFP?

1. Iyini imojula ye-transceiver?

Amamojula we-Transceiver, njengoba igama libonisa, aqondiswa kabili, futhi i-SFP ingenye yawo.Igama elithi “transceiver” liyinhlanganisela ye-“transmitter” kanye “nereceiver”.Ngakho-ke, ingasebenza njengesidluliseli nomamukeli ukuze isungule ukuxhumana phakathi kwamadivaysi ahlukene.Okuhambisana nemojula yilokho okubizwa ngokuthi ukuphela, lapho imojula ye-transceiver ingafakwa khona.Amamojula e-SFP azochazwa ngokuningiliziwe ezahlukweni ezilandelayo.
1.1 Yini i-SFP?

I-SFP imfushane kokuthi I-Small Form-factor Pluggable.I-SFP iyimojula ye-transceiver ejwayelekile.Amamojula e-SFP angahlinzeka ngoxhumo lwesivinini se-Gbit/s kumanethiwekhi futhi asekele ama-multimode namafiber emodi eyodwa.Uhlobo lwe-interface oluvame kakhulu yi-LC.Ngokubukeka, izinhlobo zefiber ezixhumekayo nazo zingabonakala ngombala wethebhu yokudonsa ye-SFP, njengoba kuboniswe kuMfanekiso B. Indandatho yokudonsa eluhlaza okwesibhakabhaka ngokuvamile isho ikhebula lemodi eyodwa, futhi indandatho yokudonsa isho ikhebula lemodi eminingi.Kunezinhlobo ezintathu zamamojula we-SFP ahlukaniswe ngokwejubane lokudlulisela: SFP, SFP+, SFP28.
1.2 Uyini umehluko phakathi kwe-QSFP?

I-QSFP imele “i-Quad Form-factor Pluggable”.I-QSFP ingabamba iziteshi ezine ezihlukene.Njenge-SFP, kokubili imicu yemodi eyodwa kanye nemodi eminingi ingaxhunywa.Isiteshi ngasinye singadlulisela amanani edatha afika ku-1.25 Gbit/s.Ngakho-ke, inani lenani ledatha lingafika ku-4.3 Gbit/s.Uma usebenzisa amamojula e-QSFP+, iziteshi ezine zingaphinda zihlanganiswe.Ngakho-ke, izinga ledatha lingafika ku-40 Gbit/s.
