Mo nga miihini whatunga, kaore pea he tauhouSFPtauranga, matou maha i roto i tewhakawhiti, kōwae whatu,pouara, Ko nga taputapu whatunga kaitahuri pāpāho i kite i te noho o taua mea, engari kei reira tonu etahi o nga kaiwhakamahi kaore 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 whakawhiti 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 (etahiwhakawhitiSFPtautoko 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 / putanga), me te kaha ngawari, e tika ana mo nga momo taputapu whatunga, peneiSFPkōwae whatu, Gigabitwhakawhiti, 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, te nuinga whakaurua ki rotowhakawhiti, pouara, 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, ka whakamahia te nuinga ki te hono i te muka whatu, te taura whatunga ranei mo te tuku raraunga.
2. TeSFPtauranga o te gigabitwhakawhiti
KikabitwhakawhitiSFPKa 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 gigabit.whakawhitiSFPtauranga 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 roto i 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 teSFPtauranga i runga i tewhakawhitime 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 tewhakawhitika 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 o te tawhiti tuku o te taura whatunga he 100 m,SFPMe whakamahi te tauranga i teSFPkōwae whatu ki te hono ki te whatu muka peke mo te tuku, me tona tawhiti tuku mōrahi ko te tawhiti tuku mōrahi o teSFPkōwae whatu, ara, 160 mita.
SFPka taea te tono tauranga kiOLTawhakawhititaputapu. He kaihanga taputapu whatunga a Shenzhen HDV Phoelectron Technology Co., LtdOLTraupapa mewhakawhitiraupapa. I te wa ano, he kaha te taputapu me te roopu rorohiko me te roopu hokohoko i mua i te hoko me muri, ka taea te whakarato i te ratonga pai mo nga kaihoko.
