ZatsopanoRF pamwamba pa ulusiyankho
Masiku ano, m'malo ovuta kwambiri a maginito amagetsi komanso kufalikira kosalekeza kwa kusokoneza maginito, momwe mungakwaniritsire kutumiza kwa maginito amagetsi a broadband modalirika, mtunda wautali komanso wokhazikika kwakhala vuto lalikulu pankhani yoyezera ndi kuyesa mafakitale. Chingwe cha RF over fiber analog broadband optical transceiver ndi njira yatsopano.kufala kwa ulusi wa kuwalayankho lopangidwa kuti lithetse vutoli.
Chipangizochi chimathandizira kusonkhanitsa ndi kutumiza ma signal a wideband nthawi yeniyeni kuchokera ku DC kupita ku 1GHz, ndipo chitha kusinthidwa mosavuta kuti chigwirizane ndi zida zosiyanasiyana zodziwira, kuphatikiza ma probes apano, ma probes amagetsi apamwamba ndi zida zina zoyezera ma frequency apamwamba. Mapeto ake otumizira ali ndi mawonekedwe olowera a 1 MΩ/50 Ω osinthika a BNC, okhala ndi kugwirizanitsa kwakukulu. Pakukonza ma signal, ma signal amagetsi amasinthidwa ndikusinthidwa kukhala ma signal a kuwala, omwe amatumizidwa kumapeto olandirira kudzera mu ulusi wa optical wa single-mode ndikubwezeretsedwanso ku ma signal amagetsi oyamba ndi module yolandirira.
Ndikoyenera kunena kuti mndandanda wa R-ROFxxxxT umaphatikiza njira yowongolera mulingo wokha (ALC), yomwe imatha kuthana ndi kusinthasintha kwa chizindikiro komwe kumachitika chifukwa cha kutayika kwa ulusi ndikuwonetsetsa kuti magwiridwe antchito nthawi zonse akamatumiza mtunda wautali. Kuphatikiza apo, gawo lotumizira lili ndi chochepetsera chosinthika komanso chosinthika, chothandizira kusintha katatu kwa 1:1/10:1/100:1. Izi zimathandiza ogwiritsa ntchito kukonza mulingo wolandirira chizindikiro kutengera zochitika zenizeni ndikukulitsa mulingo wosinthika wa dongosololi.
Kuti akwaniritse zofunikira pa mayeso a pa intaneti kapena pafoni, mndandanda wa ma module awa umathandizira magetsi a batri ndi mphamvu yakutali, ndipo uli ndi mawonekedwe anzeru oimirira omwe amalowa okha mumkhalidwe wamagetsi ochepa panthawi yosagwiritsidwa ntchito, zomwe zimapangitsa kuti batri la chipangizocho lizigwira ntchito nthawi yayitali. Magetsi owunikira a LED omwe ali kutsogolo amapereka ndemanga nthawi yeniyeni pa momwe chipangizocho chikugwirira ntchito, zomwe zimawonjezera magwiridwe antchito ndi magwiridwe antchito a chipangizocho.
Kaya muzochitika monga kuyang'anira mphamvu, kuyesa ma wailesi pafupipafupi, kapena kuyesa kafukufuku wasayansi, mndandanda wa R-ROFxxxxT ukhoza kupatsa ogwiritsa ntchito njira zodalirika, zosinthika, komanso zotsutsana kwambiri ndi kusokoneza ma signal akutali.
Kufotokozera kwa Zamalonda
Mndandanda wa R-ROFxxxxTUlalo wa RF pamwamba pa ulusiChingwe cha analog broadband optical transceiver ndi chipangizo chotumizira mauthenga chakutali cha fiber optic chomwe chapangidwira kuyeza nthawi yeniyeni zizindikiro zamagetsi za DC mpaka 1GHz m'malo ovuta amagetsi. Module yotumizira imakhala ndi 1 MΩ/50 Ω BNC input, yomwe imatha kulumikizidwa ku zipangizo zosiyanasiyana zozindikira (ma probe amakono, ma probe amphamvu kwambiri kapena zipangizo zinazake zoyezera pafupipafupi). Mu module yotumizira, chizindikiro chamagetsi cholowera chimasinthidwa ndikusinthidwa kukhala chizindikiro cha kuwala, chomwe chimatumizidwa ku module yolandira kudzera mu ulusi wa kuwala wa single-mode. Module yolandira imasandutsa chizindikiro cha kuwala kubwerera ku chizindikiro chamagetsi. Kutumiza chizindikiro cha kuwala kumayendetsedwa ndi kulamulira kwa mlingo wokha kuti kukhale ndi magwiridwe antchito olondola komanso okhazikika, osakhudzidwa ndi kutayika kwa kuwala. Ma module onse a transceiver amathandizira magetsi a batri ndi kulamulira kwakutali. Module yotumizira mauthenga a kuwala imaphatikizaponso attenuator yosinthika yosinthika (1:1/10:1/100:1) yosinthira mulingo wa chizindikiro cholandiridwa kuti chiwongolere kuchuluka kwa mphamvu. Kuphatikiza apo, chipangizocho chikapanda kugwiritsidwa ntchito, chitha kulowetsedwa kutali mu mode yoyimirira yamphamvu yochepa kuti chisunge mphamvu ya batri, ndipo kuwala kwa LED kumawonetsa momwe ntchito ikuyendera.
Zinthu zomwe zili mu malonda
Bandwidth ya DC-500 MHZ/DC-1 GHZ ndi yosankha
Chiwongola dzanja chothandizira kuyika chowongolera kuwala
Gain imasinthidwa ndipo mtundu wa mphamvu yolowera umakonzedwa bwino
Imathandizira mphamvu yakutali ndipo imagwiritsa ntchito batri, zomwe zimapangitsa kuti ikhale yosavuta kugwiritsa ntchito panja
