Mo nga miihini whatunga, kaore pea he tauhouSFPtauranga, matou maha i roto i te whakakā, kōwae whatu, pouara, media converter taputapu whatunga i kite i te oraraa o te reira, engari i reira e tonu etahi kaiwhakamahi e kore e tino mohio ki teSFPtauranga, me te whakatakoto i mua i te raupapa o nga raruraru, penei, he aha te painga oSFPtauranga,
Ko teSFPtauranga he tauranga muka whatu, canSFPtauranga huri RJ 45, aha atu. Ka aro tenei pepa ki te whakautu i nga patai maha e tino awangawangatia ana e nga kaiwhakamahi.
He aha teSFPtauranga?He putanga muka?He aha te mahi o?
SFPKo te tauranga he atanga ki te whakatutuki i te huringa tohu whakaahua hiko gigabit, ko tana mahi matua mo te huringa tohu me te tuku raraunga, ka tutuki ona tauranga ki nga paerewa IEEE 802.3ab (penei i te 1000 BASE-T), te tere o te whakawhiti ki te 1000 Mbps (etahi whakawhitiSFPtautoko tauranga 100 / 1000Mbps urutau), no reira ka kiia hoki he tauranga muka gigabit.
He aha nga painga o teSFPtauranga?Ko nga taputapu whatunga e whakamahia nuitia ana?
SFPKo te tauranga no te atanga I / O wera-wera (e pa ana ki te atanga whakauru / whakaputa), me te kaha ngawari, e tika ana mo nga momo taputapu whatunga, peneiSFPkōwae whatu, Gigabit whakawhiti, me etahi atu, ka taea te whakawhiti ki te 1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX ranei 1000 BASE-BX 10-D / U tauranga.I tua atu, ko teSFPhe hototahi whakararo te tauranga me te tautoko i te 10 / 100 / 1000Mbps.I roto i te poto, teSFPE wha nga painga nui o te tauranga:
● Tautoko i te mono wera, ka taea te whakaiti i te whakaurunga me te wa whakahaere tiaki;
● He ngawari te tauranga;
● Ko te hoahoa pakari ka whakanui i te pono;
● Hototahi ki te 10 / 100 / 1000Mbps.
1. TeSFPtauranga o teSFPkōwae whatu
SFPKo te kōwae whatu he taputapu atanga e huri ana i nga tohu hiko gigabit hei tohu whatu.Ko te paerewa ahumahi iti, me te mono gigabit whatu transceiver kōwae whakauru.E rua nga pito oSFPkōwae whatu: ko tetahi pitoSFPtauranga, ko te nuinga ka whakauruhia ki roto i te whakawhiti, te pouara, te kaitahuri pāpāho me etahi atu taputapu whatunga hei huri i nga tohu hiko ki nga tohu whatu mo te tuku;ko tetahi atu pito ko te atanga LC ranei te atanga RJ 45, e whakamahia ana hei hono i te muka whatu, te taura whatunga ranei mo te tuku raraunga.
2. TeSFPtauranga o te whakakā gigabit
Whakawhiti GigabitSFPKa taea te hono te tauranga ki nga momo momo muka (penei i te aratau kotahi me te muka multimode) me te peke whatunga (penei i te Cat5e me te Cat6) hei whakawhānui ake i te mahi whakawhiti o te whatunga katoa, engari ko te whakawhiti gigabitSFPtauranga i mua i te whakamahi me whakauru tuatahiSFPkōwae whatu, ka whakamahi i te peke muka me te peke whatunga mo te tuku raraunga.Ko nga huringa hinonga katoa i runga i te maakete i enei ra e rua neke atuSFPtauranga ka taea te hanga i nga topologia whatunga annular, whetu ranei i waenga i nga whare rereke, papa, waahi ranei ma nga taura penei i nga muka whatu me nga peke whatunga.
He aha te rereketanga oSFPtauranga me te tauranga RJ 45?
Ahakoa teSFPKo te tauranga me te tauranga RJ 45 kei a raatau katoa te reiti tuku morahi o te 1000Mbps, he rereke nga rereketanga i waenga i a raatau.
1. Nga tono rereke
Hei tauira, ko teSFPKo te tauranga i runga i te whakawhiti me taurite kiSFPkōwae whatu me te whakamahi i te peke muka ki te mohio ki te tuku raraunga;me te tauranga RJ 45 i runga i te whakawhiti ka taea te mohio ki te tuku raraunga tika ma te taura whatunga.
2. He rereke te tawhiti whakawhiti
Ko te tauranga RJ 45 te nuinga e whakahaere ana i te tuku raraunga ma te taura whatunga, ko te tawhiti rawa o te whakawhiti o te taura whatunga he 100 m,SFPMe whakamahi te tauranga i teSFPkōwae whatu ki te hono ki te oumu muka whatu mo te tuku, me tona tawhiti tuku mōrahi ko te tawhiti tuku mōrahi o teSFPkōwae whatu, ara, 160 mita.
SFPka taea te tono tauranga kiOLTme te whakawhiti taputapu.He kaihanga taputapu whatunga a Shenzhen HDV Phoelectron Technology Co., LtdOLTraupapa me te raupapa whakawhiti.I te wa ano, he kaha te roopu taputapu me te raupaparorohiko me te roopu hokohoko i mua i te hoko me muri, ka taea te whakarato i te ratonga pai mo nga kaihoko.
