Optical kis tau tus mob yog thev naus laus zis ntawm kev xa tawm hauv daim ntawv ntawm cov teeb liab kho qhov muag ntawm tus xa thiab tus txais. Cov khoom siv kho qhov muag kis tau tus mob yog los hloov ntau yam teeb liab rau hauv cov teeb liab kho qhov muag hauv cov khoom siv kho qhov muag fiber ntau kis tau tus mob, yog li cov cuab yeej siv kho qhov muag niaj hnub no feem ntau yog siv hauv fiber ntau optical. Cov cuab yeej siv kho qhov muag feem ntau yog: optical transceiver, optical MODEM, optical transceiver, optical transceiverhloov, PDH, SDH, PTN thiab lwm yam khoom siv.
Related of optical transmission technology luv luv qhia
Synchronous Optical Network (SONET) thiab Synchronous Digital Hierarchy (SDH): Ib qho kev sib txuas ntawm fiber ntau optic (tus qub yog Asmeskas tus qauv siv hauv North America, tom kawg yog tus qauv thoob ntiaj teb). Nws siv lub synchronous kis tau tus mob module (STM-1,155Mbps) raws li lub tswv yim yooj yim. Lub module yog tsim los ntawm net cov ntaub ntawv thauj khoom, ntu nyiaj siv ua haujlwm, thiab kev tswj xyuas qhov taw qhia. Nws cov yam ntxwv tseem ceeb yog sib xws nrog ntau yam PDH system.
Plesiochronous Digital Hierarchy (PDH): Pre-SONET / SDH digital transmission system, non-optical transmission mainstream khoom. Nws yog tsim los rau lub suab sib txuas lus. Tsis muaj universal standard digital signal rate thiab thav duab qauv, thiab kev sib txuas thoob ntiaj teb yog qhov nyuaj.
Wavelength Division Multiplex (WDM): Qhov tseem ceeb, Zaus Division Multiplex (FDM) yog siv los ntawm fibers optical, uas yog, FDM thev naus laus zis hauv kev kho qhov muag. Nws yog ib txoj hauv kev zoo los txhim kho lub peev xwm ntawm kev sib txuas lus kho qhov muag fiber ntau. Txhawm rau kom siv tag nrho cov peev txheej bandwidth loj hauv cheeb tsam qis ntawm ib hom fiber ntau, qhov qis qis ntawm fiber ntau tau muab faib ua ntau txoj hauv kev raws li qhov sib txawv (lossis wavelength) ntawm txhua qhov channel. Lawv xa lawv cov lus ntawm cov wavelengths sib txawv, yog li lawv tsis cuam tshuam nrog ib leeg txawm nyob rau tib lub fiber ntau. Dense Wavelength Division Multiplex (DWDM): Tsis zoo li cov kab ke WDM, DWDM systems muaj qhov sib nrug me me thiab siv bandwidth zoo dua.
Optical Add/Drop Multiplex (OADM): Ib qho khoom siv uas siv cov lim dej los yog cov khoom sib cais los ntxig lossis cais cov teeb liab kho qhov muag los ntawm kev sib faib wavelength multiplexing kis tau tus mob. OADM muaj cov teeb liab kho qhov muag nyob rau hauv WDM system los xaiv cov saum toj no / hauv qab tus nqi, hom ntawv thiab hom raws tu qauv. Tsuas yog lub teeb liab wavelength uas yuav tsum tau tapped / ntxig rau ntawm qhov node, thiab lwm cov teeb liab wavelength yog optically pob tshab los ntawm cov node. Dynamic ( saj zawg zog, reconfigurable lossis programmable) OADM yog lub hauv paus rau kev ua tiav ntawm lub nroog kho qhov muag network. Siv dynamic OADM nyob rau hauv inter-loj optical nplhaib tes hauj lwm, lub kaw lus muaj peev xwm muab tag nrho wavelength channel kev sib txuas ntawm ob lub nodes.
Optical cross interconnection (OpticalCross-connect, OXC): Cov cuab yeej siv rau optical fiber network nodes, los ntawm kev sib txuas ntawm kev sib txuas ntawm cov teeb liab kho qhov muag, yog ib qho tseem ceeb txhais tau tias kom ua tiav kev ruaj ntseg network tiv thaiv / rov qab thiab tsis siv neeg thaiv thiab saib xyuas. Nws yog tsim los ntawm WDM thev naus laus zis thiab kho qhov muag pom kev sib cais tshuab (opticalhloov).
Tag nrho cov Optical Network (AON): yog hais txog lub network system uas lub teeb liab tsuas yog dhau los ntawm hluav taws xob / kho qhov muag thiab kho qhov muag / hluav taws xob hloov pauv thaum nkag mus thiab tawm hauv lub network, thiab ib txwm muaj nyob rau hauv daim ntawv ntawm lub teeb nyob rau hauv tus txheej txheem ntawm kev sib kis thiab sib pauv hauv lub network. Hauv lwm lo lus, cov ntaub ntawv yeej ib txwm nyob hauv qhov chaw kho qhov muag thaum nws kis tau los ntawm qhov chaw ntawm qhov chaw mus rau qhov chaw ntawm qhov chaw, thiab lub wavelength dhau los ua qhov tseem ceeb tshaj plaws ntawm txhua qhov kev kho qhov muag network. Tag nrho cov-optical network yog pob tshab rau lub teeb liab vim hais tias tag nrho cov teeb liab kis tau tus mob yog nqa tawm nyob rau hauv lub optical domain. Tag nrho-optical network paub txog txoj kev los ntawm kev xaiv cov khoom siv wavelength. All-optical network tau dhau los ua thawj qhov kev xaiv ntawm cov tiam tom ntej high-speed (ultra-high-speed) broadband network vim nws cov pob tshab zoo, wavelength routing yam ntxwv, compatibility thiab scalability.
Li-Fi: Lub tshuab kev sib txuas lus kho qhov muag no siv LED-raws li lub teeb nyob hauv tsev tsis siv xov tooj cua rau kev xa cov ntaub ntawv. Thiab cov pab pawg sab saum toj hauv Li-Fi kev tshawb fawb tab tom saib dhau ntawm kev coj mus rau cov ntaub ntawv xa mus, uas yog laser-based Li-Fi kev sib txuas lus thev naus laus zis, uas tuaj yeem theoretically txhim kho tus nqi ntawm Li-Fi dhau LED los ntawm ntau dua 10 zaug. (Qhov tseeb, ob peb xyoos dhau los, kev sib kis hauv qab dej tsim los ntawm Tuam Tshoj Huako, Tebchaws Meskas thiab Iran tau tuaj yeem nce tus nqi wireless mus rau 300Gb / s ntawm 1 meter nrug. Qhov nruab nrab siv yog huab cua.)
Cov saum toj no yog cov lus qhia luv luv rau cov kev paub txog kev sib kis ntawm optical. Kuv ntseeg tias koj tau to taub dab tsi yog optical transmission technology los ntawm cov lus piav qhia luv luv saum toj no. Shenzhen HDV Phoelectron Technology LTD yog cov chaw tsim khoom tshwj xeeb hauv kev sib txuas lus kho qhov muag raws li cov khoom tseem ceeb. Txhawm rau muab kev pabcuam zoo dua rau peb cov neeg siv khoom, nws tau nruab nrog pab pawg R & D muaj zog thiab zoo heev. Lub tuam txhab cov khoom tseem ceeb yogOLTONU/ ACONU / kev sib txuas lus kho qhov muag module / kev sib txuas lus kho qhov muag module /OLTkhoom siv / Ethernethloovthiab lwm yam, los muab cov kev pabcuam txheeb ze rau ntau yam kev xav tau ntawm cov neeg siv khoom, txais tos koj tuaj.
