    Hoʻokaʻawale i nā modula SFP

    Ka manawa hoʻouna: Iulai-26-2023

    Nui nā ʻano o nā modula SFP, a ʻaʻohe ala e hoʻomaka ai nā mea hoʻohana maʻamau i ke koho ʻana i nā modula SFP, a i ʻole maopopo ʻole i ka ʻike, manaʻoʻiʻo makapō i ka mea hana, e hopena i ka hiki ʻole ke koho i kā lākou pono a i ʻole ka hui maikaʻi loa. Aia ma lalo kahi hoʻohālikelike o nā modula SFP mai nā hiʻohiʻona like ʻole e kōkua iā ʻoe e koho.
    Hoʻokaʻawale ʻia e ka helu hoʻouna:
    Wahi a nā uku like ʻole, aia nā 155M, 622M, 1.25G, 2.125G, 4.25G, 8G, a me 10G. Ma waena o lākou, 155M a me 1.25G (nā mbps āpau) i hoʻohana nui ʻia a hoʻohana nui ʻia i ka mākeke. ʻO ka ʻenehana hoʻouna ʻana o 10G ua ulu mālie, ke emi mālie nei ke kumukūʻai, a ke ulu nei ka noi i kahi ʻano piʻi; Eia naʻe, ma muli o ka liʻiliʻi o ke komo ʻana o ka pūnaewele i kēia manawa, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana a ua lohi ka ulu. ʻO kēia kiʻi: SFP module me 1.25G a me 10G wikiwiki

    Hoʻokaʻawale ʻana o ka nalu
    Wahi a nā nalu nalu like ʻole (nā nalu optic), aia nā 850nm, 1310nm, 1550nm, 1490nm, 1530nm, 1610nm. Ma waena o lākou, ʻo ka module me ka nalu o 850nm he multimode, me kahi mamao o ka hoʻouna ʻana ma lalo o 2KM (hoʻohana ʻia no ka hoʻouna ʻana ma waena a me ka pōkole, ʻoi aku ka maikaʻi ma mua o ke kumukūʻai o nā kaula pūnaewele, a ʻoi aku ka haʻahaʻa o ka lawe ʻana). ʻO ka module me ka hawewe lele o 1310nm a me 1550nm he mode hoʻokahi, me ka mamao o ka lawe ʻana o 2KM-20KM, ʻoi aku ka liʻiliʻi ma mua o nā hawewe ʻekolu ʻē aʻe, no laila ua hoʻohana nui ʻia, koho maʻamau mai kēia mau koho ʻekolu ua lawa. Hiki ke huikau me ka ʻike ʻole ʻia o nā modula olohelohe (he mau modula maʻamau me kekahi ʻike). ʻO ka mea maʻamau, e hoʻokaʻawale nā ​​mea hana i ke kala o ke apo huki, e like me ke apo huki ʻeleʻele no ka multimode, me ka nalu o 850nm; ʻO Blue kahi modula me ka lōʻihi o ka nalu o 1310nm; Hōʻike ka melemele i kahi module me ka lōʻihi nalu o 1550nm; ʻO ka poni he modula me ka lōʻihi nalu o 1490nm.

    E like me ka mea i hōʻike ʻia ma ke kiʻi ma luna, pili nā kala like ʻole me nā lōʻihi nalu like ʻole

    wps_doc_5

    E like me ka mea i hōʻike ʻia ma ka kiʻi ma luna, he module 850nm SFP ia

    Hoʻokaʻawale ma muli o ke ʻano hoʻoili
    Multimode SFP
    Ma nā ʻōlelo o ka nui, aneane ʻo 50/125mm a i ʻole 62.5/125mm nā multimode optical fiber, a ʻo ka bandwidth (ka hiki ke hoʻouna i ka ʻike o ka fiber optical) ʻo 200MHz a i 2GHz. Ke hoʻohana nei i ka transceiver optical multimode, hiki i nā fiber optical multimode ke hoʻouna i nā mamao a hiki i 5 mau kilomita. Ke hoʻohana nei i nā diodes māmā a i ʻole nā ​​laser e like me nā kumu kukui. He ʻeleʻele ke apo huki a i ʻole ke kala kino.
    SFP mode hoʻokahi
    ʻO ka nui o ka fiber mode hoʻokahi he 9-10 / 125mm, a hoʻohālikelike ʻia me ka fiber multimode, loaʻa iā ia ka bandwidth palena ʻole a me nā hiʻohiʻona haʻahaʻa haʻahaʻa. No laila, i ka hoʻouna ʻana i nā mamao lōʻihi, ʻoi aku ka makemake o ka hoʻouna ʻana i ke ʻano hoʻokahi. Hoʻohana pinepine ʻia ka transceiver optical mode hoʻokahi no ka hoʻouna ʻana i kahi lōʻihi, i kekahi manawa a hiki i 150 a 200 mau kilomita. E hoʻohana iā LD a i ʻole LED me nā laina kikoʻī liʻiliʻi e like me ke kumu kukui. ʻO ke apo huki a i ʻole ke kala o ke kino he uliuli, melemele, a poni paha. (Ua wehewehe maopopo ʻia nā lōʻihi nalu e pili ana i nā kala like ʻole.)
