Thaum peb kis tau los ntawm qhov deb, peb feem ntau siv fiber ntau los kis. Vim hais tias qhov kev ncua deb ntawm optical fiber ntau nyob deb heev, feem ntau hais lus, qhov kev ncua deb ntawm ib hom optical fiber ntau yog ntau tshaj 10 kilometers, thiab qhov kev ncua deb ntawm multi-mode optical fiber yuav ncav cuag 2 km. Hauv fiber ntau optic tes hauj lwm, peb feem ntau siv fiber ntau optic transceivers. Yog li, yuav ua li cas txuas lub fiber-optic transceiver? Cia peb xav.
1. Lub luag haujlwm ntawm optical fiber-optic transceivers
1. Fiber transceiver tuaj yeem txuas Ethernet kis nrug deb thiab nthuav dav Ethernet kev pab cuam lub vojvoog.
2. Lub fiber ntau transceiver tuaj yeem hloov dua siab tshiab ntawm 10M, 100M, lossis 1000M Ethernet hluav taws xob interface thiab optical interface.
3, siv cov fiber ntau optical transceiver los tsim lub network tuaj yeem txuag cov peev hauv network.
4. Fiber optic transceiver ua rau kev sib tshuam ntawm server, repeater, hub, davhlau ya nyob twg thiab lub davhlau ya nyob twg zoo dua.
5, fiber ntau transceiver muaj microprocessor thiab kuaj mob interface, tuaj yeem muab ntau yam ntaub ntawv txuas cov ntaub ntawv ua haujlwm.
2. Qhov twg yog qhov tso tawm lossis qhov twg tau txais fiber ntau transceiver?
Thaum siv optical fiber transceiver, ntau tus phooj ywg yuav ntsib cov lus nug no:
1. Yuav tsum siv cov fiber ntau optic transceiver ua khub?
2, optical fiber transceiver tsis muaj cov ntsiab lus, ib qho yuav tau txais ib qho yog xa? Los yog siv tau ob fiber ntau transceivers los ua ib khub?
3. Yog hais tias lub optical fiber transceiver yuav tsum tau siv ua khub, ib khub yuav tsum yog tib hom thiab qauv? Los yog koj tuaj yeem siv kev sib xyaw ua ke ntawm ib lub npe?
Ntau tus phooj ywg tej zaum yuav muaj lo lus nug no nyob rau hauv tus txheej txheem ntawm kev siv qhov project, yog li nws yog dab tsi? Teb: optical fiber ntau transceiver li photoelectric hloov dua siab tshiab cov cuab yeej feem ntau yog siv nyob rau hauv khub, tab sis kuj yuav tshwm sim optical fiber transceiver thiab optical fiber hloov, optical fiber transceiver thiab SFP transceiver pairing siv kuj yog ib txwm, nyob rau hauv txoj cai, ntev li ntev raws li lub optical kis tau tus mob wavelength. tib yam, lub teeb liab encapsulation hom ntawv yog tib yam thiab txhawb qee qhov kev cai tuaj yeem paub txog kev sib txuas lus fiber ntau. General ib hom ob fiber ntau (ib txwm kev sib txuas lus xav tau ob fiber ntau) transceiver tsis hais txog ntawm lub transmitter thiab tau txais kawg, tsuav yog ob leeg siv tau. Tsuas yog ib qho fiber ntau transceiver (kev sib txuas lus ib txwm xav tau fiber ntau) yuav muaj qhov sib kis sib kis thiab qhov kawg tau txais.
Txawm hais tias nws yog ob chav fiber ntau transceiver los yog ib qho fiber ntau transceiver yuav tsum tau siv ua khub, cov hom sib txawv tuaj yeem sib haum nrog kev sib tshuam. Tab sis tus nqi, wavelength, thiab qauv yog tib yam. Qhov ntawd yog hais tias, tus nqi sib txawv (100 thiab gigabit), qhov sib txawv wavelengths (1310nm thiab 1300nm) tsis tuaj yeem sib txuas lus nrog ib leeg, ntxiv rau, txawm tias tib hom ntawm ib leeg fiber ntau transceiver thiab ob chav fiber ntau ua ib khub tsis sib txuas. Yog li cov lus nug yog, dab tsi yog ib qho fiber ntau transceiver, thiab dab tsi yog ob lub fiber ntau transceiver? Qhov txawv ntawm lawv yog dab tsi?
3. Dab tsi yog ib qho fiber ntau transceiver? Dab tsi yog ob-fiber transceiver?
Tib fiber ntau transceiver yog hais txog kev siv ib hom kev kho qhov muag cable, ib leeg fiber ntau transceiver tsuas yog ib qho tseem ceeb, ob qho kawg yog txuas nrog cov tub ntxhais, ob qho tib si kawg ntawm lub transceiver siv lub teeb wavelengths sib txawv, yog li nws tuaj yeem xa cov teeb liab teeb liab hauv ib qho tseem ceeb. Muab ob npaug rau fiber ntau transceiver yog siv ob lub hauv paus, ib qho xa tuaj, ib qho kawg yog cov plaub hau, lwm qhov kawg yuav tsum tau muab tso rau hauv qhov chaw nres nkoj, yog ob qhov kawg los hla.
1, ib leeg fiber ntau transceiver
Ib qho fiber ntau transceiver yuav tsum paub txog ob qho tib si kis tau tus mob thiab qhov tau txais kev ua haujlwm. Nws siv cov nthwv dej faib multiplexing thev naus laus zis los xa ob lub teeb pom kev kho qhov muag ntawm qhov sib txawv wavelengths hauv ib qho khoom siv fiber ntau kom paub txog kev sib kis thiab kev txais tos.
Yog li ib hom ib leeg-fiber transceiver kis tau los ntawm fiber ntau, yog li kev xa tawm thiab tau txais lub teeb kis tau los ntawm cov tub ntxhais fiber ntau tib lub sijhawm. Hauv qhov no, ob lub wavelengths ntawm lub teeb yuav tsum tau siv kom ua tiav kev sib txuas lus ib txwm.
Yog li ntawd, lub optical module ntawm ib hom ib leeg-fiber transceivers muaj ob lub qhov muag wavelengths, feem ntau 1310nm / 1550nm, yog li ob lub terminals ntawm ib khub ntawm transceivers yuav txawv. Ib-kawg transceiver kis 1310nm thiab tau txais 1550nm. Ntawm qhov kawg, nws tawm 1550nm thiab tau txais 1310nm. Yog li yooj yim rau cov neeg siv kom paub qhov txawv, feem ntau yuav siv cov ntawv hloov. Qhov kawg A (1310nm / 1550nm) thiab kawg B (1550nm / 1310nm) tshwm sim. Cov neeg siv yuav tsum yog AB ua khub siv, tsis yog AA lossis BB txuas. AB tsuas yog siv los ntawm ib leeg fiber ntau transceiver.
2, ob chav fiber ntau transceiver
Ob chav fiber ntau transceiver muaj TX chaw nres nkoj (chaw nres nkoj) thiab RX chaw nres nkoj (ceiv chaw nres nkoj). Ob qhov chaw nres nkoj muaj tib lub wavelength ntawm 1310nm, thiab kev txais tos yog 1310nm, yog li ob qhov sib npaug ntawm cov khoom siv kho qhov muag tau siv rau kev sib txuas.
3, yuav ua li cas paub qhov txawv ntawm ib leeg fiber ntau transceiver thiab ob fiber ntau transceiver
Muaj ob txoj hauv kev kom paub qhov txawv ntawm ib qho fiber ntau transceivers los ntawm ob lub fiber ntau transceivers.
① Thaum lub optical fiber transceiver yog embedded nyob rau hauv lub optical module, lub optical fiber transceiver muab faib mus rau hauv ib tug fiber ntau transceiver thiab ob fiber ntau transceiver raws li tus naj npawb ntawm cov kev cob cog rua optical fiber jumper cores. Ib qho fiber ntau transceiver (txoj cai) txuas nrog lub fiber core, uas yog lub luag haujlwm rau ob qho tib si xa cov ntaub ntawv thiab tau txais cov ntaub ntawv, thaum ob lub fiber ntau transceiver (sab laug) txuas nrog ob lub fiber ntau cores, ib qho yog lub luag haujlwm rau kev xa cov ntaub ntawv thiab cov lwm tus yog lub luag haujlwm rau kev txais cov ntaub ntawv.
② Thaum lub optical fiber ntau transceiver tsis muaj embedded optical module, nws yog tsim nyog los paub qhov txawv seb lub fiber ntau transceiver los yog dual fiber ntau transceiver raws li lub inserted optical module. Thaum lub fiber ntau optical transceiver yog ntxig nrog ib qho fiber ntau bidirectional optical module, uas yog, lub interface yog ib hom, qhov fiber ntau transceiver (txoj cai); Thaum lub fiber ntau transceiver yog ntxig nrog ob fiber ntau bidirectional optical module, los yog interface yog duplex hom, lub transceiver yog ob fiber ntau transceiver (sab laug daim duab).
