Optical fiber ntau transceiver yog Ethernet kis tau tus mob media conversion unit uas sib pauv luv luv twisted khub hluav taws xob signals thiab ntev-ntev optical signals.Nws yog feem ntau muab faib ua ib leeg-fiber optical transceivers thiab dual-fiber optical transceivers raws li lawv xav tau Tom ntej no, peb yuav qhia kom meej dab tsi yog ib hom single-fiber / dual-fiber optical transceiver?Dab tsi yog qhov txawv ntawm ib hom ib leeg-fiber thiab ib hom dual-fiber transceivers?Cov phooj ywg txaus siab, cia peb saib!
Dab tsi yog ib hom single-fiber optical transceiver?
Tib hom ib leeg-fiber optical fiber ntau transceiver, ib leeg-fiber khoom yuav txuag tau ib nrab ntawm cov fiber ntau optical, uas yog, txais cov ntaub ntawv thiab kev sib kis ntawm ib qho fiber ntau.
Ib leeg-fiber optical fiber transceiver: Cov ntaub ntawv tau txais thiab xa tawm yog kis ntawm ib qho fiber ntau optical.Raws li lub npe qhia, cov khoom siv fiber ntau tuaj yeem txuag tau ib nrab ntawm cov khoom siv kho qhov muag, uas yog, kom tau txais thiab xa cov ntaub ntawv ntawm ib qho fiber ntau, uas yog qhov tsim nyog nyob rau hauv qhov chaw uas muaj fiber ntau nruj.Cov khoom siv no siv cov thev naus laus zis ntawm wavelength division multiplexing, thiab cov wavelengths siv feem ntau yog 1310nm thiab 1550nm.Txawm li cas los xij, vim tias tsis muaj kev sib koom ua ke thoob ntiaj teb tus qauv rau ib leeg-fiber transceiver cov khoom, cov khoom ntawm cov tuam txhab sib txawv yuav tsis sib haum thaum sib cuam tshuam.Tsis tas li ntawd, vim yog siv wavelength division multiplexing, ib leeg-fiber transceiver khoom feem ntau muaj cov yam ntxwv ntawm cov teeb liab loj attenuation.Tam sim no, feem ntau ntawm cov optical fiber transceivers ntawm kev ua lag luam yog dual-fiber khoom.Cov khoom zoo li no yog cov paub tab thiab ruaj khov, tab sis xav tau fiber ntau optical.
Dab tsi yog ib hom dual-fiber optical transceiver?
Ib hom dual-fiber optical transceiver, ib leeg-fiber bidirectional optical transceiver hom yog photoelectric hloov dua siab tshiab cov cuab yeej, qhov kom zoo dua yog txuag ib nrab ntawm optical fiber.
Ib leeg-fiber bidirectional optical fiber transceiver yog ib tug photoelectric hloov dua siab tshiab ntaus ntawv uas siv wavelength division multiplexing thev naus laus zis los xa thiab tau txais cov ntaub ntawv ntawm ib leeg fiber ntau optical thiab hloov network hluav taws xob thiab cov teeb liab kho qhov muag.Ib leeg-fiber bidirectional fiber optic transceivers tau dhau los ua neeg nyiam nyob rau xyoo tas los no.Qhov zoo dua yog tias nws tuaj yeem txuag tau ib nrab ntawm cov khoom siv kho qhov muag, thiab qhov tsis muaj ib nrab ntawm cov khoom siv kho qhov muag yog tias tam sim no tsis muaj kev sib koom ua ke thoob ntiaj teb.Cov khoom tsim los ntawm ntau lub tuam txhab yog feem ntau sib xws thiab me ntsis ruaj khov dua li cov khoom siv fiber ntau dual.Tam sim no, fiber ntau optic transceivers ntawm kev ua lag luam tseem yog cov khoom lag luam dual-fiber.
Dab tsi yog qhov txawv ntawm ib hom ib leeg-fiber thiab ib hom dual-fiber transceivers?
Ib hom multimode nyob ntawm qhov kho qhov muag cable.Ib leeg-fiber dual-fiber hais txog ib-core optical fiber kis tau tus mob los yog ob-core optical fiber kis tau tus mob;single-mode hais txog kev siv ib hom optical fiber cable.Ob qho tib si txuas nrog cov tub ntxhais no, thiab cov transceivers ntawm ob qhov kawg siv qhov sib txawv ntawm qhov sib txawv, yog li lawv tuaj yeem xa cov teeb liab kho qhov muag hauv ib qho tseem ceeb.Lub dual-fiber transceiver siv ob lub cores, ib qho xa tuaj thiab ib qho tau txais, thiab ib qho kawg yog qhov kawg xa thiab lwm qhov kawg yuav tsum tau muab tso rau hauv qhov chaw txais khoom, uas yog, ob qhov kawg yuav tsum hla.
Hauv cov ntawv thov tshwj xeeb, ib hom ob hom, ntau hom ntau hom yog siab dua li ib hom, feem ntau nyob rau hauv cov kab hluav taws xob tsawg dua 500m, ntau hom tuaj yeem sib ntsib, txawm hais tias qhov kev ua tau zoo tsis zoo li ib leeg. - hom.Ib hom yog siv nyob rau hauv ib puag ncig ntawm ntau tshaj 500m los yog siab bandwidth yuav tsum, feem ntau nyob rau hauv loj-scale venues xws li enterprise-theem daim ntawv thov.Vim tias kev ua haujlwm ruaj khov thiab kev ua haujlwm ntawm optical fiber modules zoo dua li transceivers, nyob rau hauv ib hom ntawv thov ib puag ncig nrog kev ua haujlwm siab, ob peb lub tuam txhab yuav siv transceivers, tab sis ncaj qha siv modules hloov.Muaj tsawg dua manufacturers ntawm analog transceivers thiab tus nqi siab dua.
Ib qho fiber ntau thiab dual fiber ntau feem ntau muaj ob qhov chaw nres nkoj, thiab ob qhov chaw nres nkoj ntawm dual fiber ntau nyob ze rau ib leeg.Lawv raug cim TX, RX, ib qho kev xa tawm thiab ib qho tau txais, feem.Ob qhov chaw nres nkoj ntawm ib leeg fiber ntau yog P1.P2 qhia tias ob qhov chaw nres nkoj tuaj yeem xa thiab tau txais nyias, uas yog, ib qho chaw nres nkoj yog siv los xa thiab txais, yog li nws hu ua ib qho fiber ntau.Lub optical transceivers TX thiab RX sawv cev tau txais thiab xa.Muaj ob hom optical transceivers: ib qho yog ib hom thiab ib qho yog dual-hom, ib yam li txoj kev loj yuav tsuas yog congested yog tias tsuas muaj ib kab xwb, tab sis nws yog ntau smoother yog tias nws yog ob-kab, yog li Nws yog pom tseeb tias qhov kev ruaj ntseg ntawm dual-hom receiver Zoo point.
Ib qho fiber ntau tsuas yog ib qho kev sib txuas ntawm ob lub transceivers, dual fiber ntau dua, koj yuav tsum siv ob fibers, tus nqi ntawm ib fiber ntau dua me ntsis.Lub multi-mode transceiver tau txais ntau hom kev sib kis, qhov sib kis ntawm qhov deb kuj luv, thiab ib hom transceiver tsuas tau txais ib hom nkaus xwb;qhov kis tau tus mob nyob deb kuj ntev.Txawm hais tias ntau hom tau raug tshem tawm, tab sis vim yog tus nqi qis, tseem muaj ntau yam siv hauv kev saib xyuas thiab kev sib kis luv luv.Multi-mode transceivers sib xws rau ntau hom optical fibers, ib hom thiab ib hom sib txuas, thiab tsis tuaj yeem sib xyaw.
