Hariho ubwoko bwinshi bwa modul ya SFP, kandi abakoresha basanzwe akenshi ntibafite uburyo bwo gutangira muguhitamo modul ya SFP, cyangwa se ntibanasobanukirwe namakuru, bizera buhumyi uwabikoze, bikaviramo kutabasha guhitamo ibyabo bikwiye cyangwa byiza.Hasi ni urutonde rwamasomo ya SFP muburyo butandukanye kugirango igufashe guhitamo.
Gutondekanya ukurikije igipimo cyo kohereza:
Ukurikije ibipimo bitandukanye, hariho 155M, 622M, 1.25G, 2.125G, 4.25G, 8G, na 10G.Muri byo, 155M na 1.25G (byose muri mbps) bikoreshwa cyane kandi bikoreshwa cyane ku isoko.Ikoranabuhanga ryo kohereza rya 10G ryakuze buhoro buhoro, igiciro nacyo kigenda kigabanuka buhoro buhoro, kandi icyifuzo kiratera imbere mu kuzamuka;Ariko, kubera igipimo gito cyurusobe rwinjira muri iki gihe, igipimo cyo gukoresha kiri kurwego rwo hasi kandi iterambere riratinda.Igishushanyo gikurikira: Module ya SFP ifite 1.25G na 10G yihuta
Ibyiciro byumurongo
Ukurikije uburebure butandukanye (optique yumurongo wa optique), hariho 850nm, 1310nm, 1550nm, 1490nm, 1530nm, 1610nm.Muri byo, module ifite uburebure bwa 850nm ni multimode, hamwe nintera yohereza munsi ya 2KM (ikoreshwa mugukwirakwiza intera ndende kandi ngufi, inyungu iri munsi yikiguzi cyinsinga zumuyoboro, kandi igihombo cyohereza kiri hasi).Module ifite uburebure bwa 1310nm na 1550nm nuburyo bumwe, hamwe nintera yo kohereza ya 2KM-20KM, ikaba ihendutse ugereranije nubundi burebure butatu, Noneho rero irakoreshwa cyane, muri rusange guhitamo muri ubu buryo butatu birahagije.Module yambaye ubusa (ni module isanzwe hamwe namakuru ayo ari yo yose) irashobora kwitiranya bitagoranye.Mubisanzwe, abayikora bazatandukanya ibara ryimpeta yo gukurura, nkimpeta yo gukurura umukara kuri multimode, hamwe nuburebure bwa 850nm;Ubururu ni module ifite uburebure bwa 1310nm;Umuhondo ugereranya module ifite uburebure bwa 1550nm;Umutuku ni module ifite uburebure bwa 1490nm.
Nkuko bigaragara ku gishushanyo cyavuzwe haruguru, amabara atandukanye ahuye nuburebure butandukanye
Nkuko bigaragara ku gishushanyo cyavuzwe haruguru, ni module ya 850nm ya SFP
Ibyiciro bishingiye kuburyo bwo kohereza
Multimode SFP
Ukurikije ubunini, fibre optique hafi ya yose ni 50 / 125mm cyangwa 62.5 / 125mm, naho umurongo mugari (ubushobozi bwo kohereza amakuru ya fibre optique) muri rusange 200MHz kugeza 2GHz.Iyo ukoresheje transimeri ya optique ya optique, fibre optique irashobora kohereza intera igera kuri kilometero 5.Gukoresha diode cyangwa urumuri rusohora urumuri.Gukurura impeta cyangwa ibara ry'umubiri ni umukara.
Uburyo bumwe SFP
Ingano ya fibre yuburyo bumwe ni 9-10 / 125mm, kandi ugereranije na fibre fibre, ifite umurongo utagira ingano hamwe nibiranga igihombo cyo hasi.Kubwibyo, iyo wohereje intera ndende, uburyo bumwe bwo kohereza burahitamo.Uburyo bumwe optique transceiver ikoreshwa mugukwirakwiza intera ndende, rimwe na rimwe igera kuri kilometero 150 kugeza 200.Koresha LD cyangwa LED hamwe n'imirongo migufi igaragara nkumucyo.Gukurura impeta cyangwa ibara ry'umubiri ni ubururu, umuhondo, cyangwa umutuku.(Uburebure bwumurongo uhuye namabara atandukanye birasobanuwe neza kuri bo.)
