Nrog rau qhov xav tau ntau ntxiv ntawm lub network, ntau yam khoom siv hauv network tau tsim los ua kom tau raws li qhov xav tau no.Fiber media converter yog ib qho tseem ceeb ntawm cov khoom siv no.Nws nta muaj peev xwm bandwidth siab, kev ua haujlwm ntev thiab kev ntseeg tau, ua rau nws nrov hauv kev sib txuas lus niaj hnub.Cov ntawv tshaj tawm no yuav los tshawb txog qee lub hauv paus thiab nthuav qhia ntau daim ntawv thov piv txwv ntawm fiber ntau media converter.

Basics ntawm Fiber Media Converter

Fiber Media Converter yog ib qho khoom siv uas tuaj yeem hloov lub teeb liab hluav taws xob rau hauv lub teeb nthwv dej ntawm tooj liab UTP (unshielded twisted khub) tes hauj lwm thiab fiber ntau optic tes hauj lwm.Raws li peb txhua tus paub, piv nrog Ethernet cable, fiber ntau optic cables muaj kev sib kis ntev dua, tshwj xeeb tshaj yog ib hom fiber ntau cables.Yog li ntawd, fiber ntau media converters pab cov neeg ua haujlwm daws cov teeb meem sib kis tau zoo kawg nkaus.
Fiber media converters feem ntau yog cov txheej txheem tshwj xeeb thiab muaj los txhawb ntau hom network thiab cov ntaub ntawv tus nqi.Thiab lawv kuj muab fiber ntau-rau-fiber hloov dua siab tshiab ntawm ib hom thiab multimode fiber ntau.Tsis tas li ntawd, qee qhov fiber ntau media converters xws li tooj liab-rau-fiber thiab fiber-rau-fiber media converters muaj peev xwm ntawm wavelength hloov dua siab tshiab los ntawm kev siv SFP transceivers.

Raws li cov qauv sib txawv, fiber ntau media converters tuaj yeem muab faib ua ntau hom.Muaj kev tswj hwm kev hloov pauv hloov pauv thiab tsis tswj hwm kev hloov pauv hloov pauv.Qhov sib txawv ntawm lawv yog tias tom kawg tuaj yeem muab kev saib xyuas network ntxiv, kev kuaj pom qhov tsis raug thiab kev teeb tsa chaw taws teeb.Kuj tseem muaj tooj liab-rau-fiber media converter, serial rau fiber ntau media converter thiab fiber-rau-fiber media converter.

Daim ntawv thov ntawm Hom Fiber Media Converters
Nrog rau ntau qhov zoo uas tau hais los saum no, fiber ntau media converters tau dav siv los txuas tooj liab tes hauj lwm thiab kho qhov muag.Qhov no feem ntau yog los qhia ob hom fiber ntau media converter daim ntawv thov.

Fiber-rau-Fiber Media Converter
Hom fiber ntau media converter no tso cai rau kev sib txuas ntawm ib hom fiber ntau (SMF) thiab multimode fiber (MMF), suav nrog ntawm qhov sib txawv "lub zog" fiber ntau thiab ntawm ib leeg-fiber thiab dual fiber.Hauv qab no yog qee qhov kev thov piv txwv ntawm fiber-rau-fiber media converter.

Multimode rau Ib Hom Fiber Daim Ntawv Thov
Txij li thaum SMF txhawb kev ncua ntev dua MMF, nws yog ib qho uas pom tias kev hloov ntawm MMF rau SMF hauv kev lag luam tes hauj lwm.Thiab fiber ntau-rau-fiber media converter tuaj yeem txuas MM network hla SM fiber ntau nrog kev ncua mus txog 140km.Nrog rau lub peev xwm no, kev sib txuas ntev ntawm ob lub Gigabit Ethernet keyboards tuaj yeem pom tau siv ob peb Gigabit fiber ntau-rau-fiber converters (raws li qhia hauv daim duab hauv qab no).

Dual Fiber rau Ib-Fiber Hloov Daim Ntawv Thov
Ib leeg-fiber feem ntau ua haujlwm nrog ob-txoj kev wavelengths, feem ntau hu ua BIDI.Thiab feem ntau siv wavelengths ntawm BIDI ib leeg-fiber yog 1310nm thiab 1550nm.Nyob rau hauv daim ntawv thov nram qab no, ob lub dual fiber media converters yog txuas los ntawm ib hom fiber ntau cable.Txij li thaum muaj ob qhov sib txawv wavelengths ntawm fiber ntau, lub transmitter thiab receiver ntawm ob qhov kawg yuav tsum tau sib phim.

Serial rau Fiber Media Converter
Hom xov xwm converter no muab fiber ntau txuas rau serial raws tu qauv tooj liab sib txuas.Nws tuaj yeem txuas nrog RS232, RS422 lossis RS485 chaw nres nkoj ntawm lub khoos phis tawj lossis lwm yam khoom siv, daws cov teeb meem ntawm ib txwm muaj RS232, RS422 lossis RS485 kev sib txuas lus tsis sib haum xeeb ntawm qhov deb thiab tus nqi.Thiab nws kuj txhawb point-to-point thiab multi-point configurations.

Daim ntawv thov RS-232
RS-232 fiber ntau converters tuaj yeem ua haujlwm raws li cov khoom siv asynchronous, txhawb kev nrawm mus txog 921,600 baud, thiab txhawb nqa ntau yam ntawm cov khoom siv hluav taws xob ntws tswj kom muaj kev sib txuas tsis sib haum nrog cov khoom siv sib txuas feem ntau.Hauv qhov piv txwv no, ib khub ntawm RS-232 converters muab cov kev sib txuas ntawm lub PC thiab lub davhlau ya nyob twg uas tso cai rau nkag mus rau ntau yam ntaub ntawv los ntawm fiber ntau.

Daim ntawv thov RS-485
RS-485 fiber ntau converters yog siv nyob rau hauv ntau qhov chaw siv ntau qhov chaw uas ib lub computer tswj ntau yam khoom siv sib txawv.Raws li pom hauv daim duab hauv qab no, ib khub ntawm RS-485 converters muab ntau qhov kev sib txuas ntawm cov khoom siv hauv tsev thiab txuas nrog ntau cov khoom siv poob ntawm fiber ntau.

Cov ntsiab lus
Kev cuam tshuam los ntawm kev txwv ntawm Ethernet cables thiab nce kev sib txuas ceev, cov tes hauj lwm tau dhau los ua qhov nyuaj.Daim ntawv thov ntawm fiber ntau media converters tsis tsuas yog kov yeej cov kev txwv nyob deb ntawm cov tsoos network cables, tab sis ua rau koj cov tes hauj lwm sib txuas nrog ntau hom xov xwm xws li twisted khub, fiber ntau thiab coax.

Yog tias koj xav tau ib qho kev hloov pauv xov xwm rau koj cov haujlwm FTTx & Optical Access nyob rau theem no, thov hu rau peb ntawminfo@jha-tech.comyog xav paub ntxiv.
