Tam sim no, muaj ntau yam txawv teb chaws thiab domestic manufacturers ntawmfiber ntau optic transceiversnyob rau hauv kev ua lag luam, thiab lawv cov khoom kab kuj nplua nuj heev.Cov hom fiber ntau optic transceivers kuj txawv, feem ntau muab faib ua khib-mounted optical transceivers, desktop optical transceivers thiab card-type optical transceivers.
Lub optical fiber ntau transceiver yog Ethernet kis tau tus mob media conversion unit uas sib pauv luv luv twisted-pair hluav taws xob signals thiab ntev-ntev optical signals.Nws tseem hu ua photoelectric converter nyob rau hauv ntau qhov chaw thiab siv nyob rau hauvCov khoom siv kho qhov muag sib txuas lus.
Dav dav dua wider.Optical fiber ntau kis tau tus mob cov khoom xws li xov tooj optical transceivers thiab optical fiber nkag khoom yuav ua tau kom kis tau tus mob ntawm cov pab kiag li lawm los ntawm optical transceivers.Feem ntau, optical transceivers muab faib ua ib hom thiab ntau hom, ib leeg-fiber thiab dual-fiber.Lub neej ntawd interface hom yog SC.FC, LC, thiab lwm yam kuj tuaj yeem teeb tsa raws li cov neeg siv khoom xav tau.Qhov kev ncua deb yog feem ntau 25 kilometers, 40 kilometers, 60 kilometers, thiab 80 kilometers., 100 km, 120 km, thiab lwm yam.
Ib hom thiab ntau hom optical transceivers
Tib hom txhais tau hais tias cov teeb liab optical propagates los ntawm ib tug channel, thaum dual-hom los yog ntau hom yog roughly tib yam thiab propagates los ntawm dual-channel los yog multi-channel.Thaum tus neeg siv xaiv seb puas yuav kis tau los ntawm ib hom lossis ntau hom, qhov tseem ceeb txiav txim siab yog qhov kev ncua deb uas tus neeg siv yuav tsum tau kis.Ib hom kis tau tus mob muaj tsawg attenuation, tab sis qhov kis tau tus mob qeeb qeeb.Nws yog tsim rau kev sib kis mus ntev.Feem ntau, qhov kev ncua deb yog ntau tshaj 5 mais.Nws yog qhov zoo tshaj plaws los xaiv ib hom fiber ntau.Multimode kis tau tus mob muaj ib tug loj attenuation, tab sis qhov kis tau tus mob ceev yog ceev.Rau kev sib kis luv luv, feem ntau qhov kev ncua deb tsawg dua 5 mais, thiab ntau hom fiber ntau yog qhov kev xaiv zoo tshaj.
Tib fiber ntau thiab dual fiber optical transceiver
Ib leeg fiber ntau yog hais txog ib leeg-core optical fiber uas xa mus rau ib tug tub ntxhais;dual fiber ntau yog hais txog lub dual-core optical fiber uas kis tau ntawm ob lub cores, ib qho tau txais thiab ib qho kev xa tawm.Feem ntau, cov neeg siv feem ntau sivdual-fiber, vim tias dual-fiber yog qhov zoo dua ntawm tus nqi.Ib leeg fiber ntau feem ntau yog siv thaum lub optical cable yog nruj heev.Piv txwv li, yog tias 12-core fiber ntau yog dual-core, tsuas yog 6 lub network tuaj yeem kis tau;yog tias 12-core fiber ntau yogib leeg-fiber, 50% ntawm cov xaim tuaj yeem txuag tau.
FC, SC, LC optical transceiver
FC, SC, thiab LC yog hom pigtail interface, thiab SC yog qhov feem ntau siv pigtail interface.Thaum muas ib qho optical transceiver interface, ua tib zoo saib seb qhov kev sib txuas no puas phim lub pigtail interface koj muab.Tau kawg, kuj tseem muaj ntau hom optical cables nyob rau hauv kev ua lag luam, xws li FC ntawm ib kawg thiab SC ntawm lwm qhov kawg.SFP optical modulessiv ntau zaus hauv LC.
Qhov kev ncua deb ntawm lub optical transceiver nyob ntawm tus neeg siv qhov kev xaiv hauv daim ntawv thov tiag tiag, thiab kev sib kis ntawm ob lub cuab yeej tuaj yeem xaiv tau raws li qhov sib thooj optical transceiver.
Cov ntsiab lus: Thaum xaiv ib qho optical fiber transceiver, xyuam xim tshwj xeeb rau daim ntawv thov.Yog tias xaiv qhov optical transceiver tsis ncaj ncees lawm, nws yuav ua rau lub chaw ua haujlwm lossis chaw taws teeb xov tooj optical transceiver lossis lwm yam khoom siv tsis ua haujlwm zoo lossis pigtail interface tsis tuaj yeem txuas nrog.Cov teeb meem ntxaws ntxaws tuaj yeem Tham nrog cov chaw tsim khoom kom paub meej tias koj yuav cov khoom zoo.
