ZatsopanoRF pa fiberyankho

Masiku ano kuchulukirachulukira kwamagetsi amagetsi komanso kufalikira kosalekeza kwa zosokoneza zamagetsi, momwe mungakwaniritsire kukhulupirika kwambiri, mtunda wautali komanso kusasunthika kosasunthika kwa ma sign amagetsi a wideband kwakhala vuto lalikulu pantchito yoyezera ndi kuyesa mafakitale. Ulalo wa RF pa fiber analogi Broadband Optical transceiver ndiwotsogola kwambirikufalikira kwa CHIKWANGWANIyankho lokonzedwa kuti lithetse vutoli.

Chipangizochi chimathandizira kusonkhanitsa nthawi yeniyeni ndi kutumiza ma siginecha a wideband kuchokera ku DC kupita ku 1GHz, ndipo imatha kusinthidwa mosavuta ndi zida zosiyanasiyana zozindikirira, kuphatikiza ma probe apano, ma probe apamwamba kwambiri ndi zida zina zoyezera pafupipafupi. Mapeto ake otumizira amakhala ndi mawonekedwe olowera a 1 MΩ/50 Ω osinthika a BNC, okhala ndi kuyanjana kwakukulu. Panthawi yokonza zizindikiro, zizindikiro zamagetsi zimasinthidwa ndikusinthidwa kukhala zizindikiro za kuwala, zomwe zimatumizidwa kumalo olandirira kudzera muzitsulo zamtundu umodzi wamtundu umodzi ndikubwezeretsedwanso kumagetsi oyambirira amagetsi ndi gawo lolandira.

Ndikoyenera kutchula kuti mndandanda wa R-ROFxxxxT umagwirizanitsa njira yodzitetezera (ALC), yomwe imatha kuthana ndi kusinthasintha kwa zizindikiro zomwe zimayambitsidwa ndi kutayika kwa fiber ndikuwonetsetsa kuti zimagwira ntchito nthawi yayitali. Kuphatikiza apo, gawo lopatsirali lili ndi chosinthira chosinthika komanso chosinthika, chothandizira kusintha katatu kwa 1: 1/10: 1/100: 1. Izi zimathandiza ogwiritsa ntchito kukhathamiritsa mulingo wolandirira ma siginecha kutengera zochitika zenizeni ndikukulitsa kusinthika kwadongosolo.

Kuti mukwaniritse zofunikira pakuyesa kumunda kapena mafoni, ma module awa amathandizira mphamvu ya batri ndi kuwongolera kwakutali, ndipo imakhala ndi njira yoyimilira yanzeru yomwe imalowa m'malo opanda mphamvu panthawi yosagwiritsa ntchito, ndikukulitsa moyo wa batri wa chipangizocho. Zowunikira zowunikira za LED pagawo lakutsogolo zimapereka ndemanga zenizeni zenizeni pa momwe ntchito ikugwirira ntchito, kupititsa patsogolo magwiridwe antchito ndi magwiridwe antchito a zida.

Kaya muzochitika monga kuyang'anira mphamvu, kuyesa maulendo a wailesi, kapena kufufuza kafukufuku wa sayansi, mndandanda wa R-ROFxxxxT ukhoza kupatsa ogwiritsa ntchito njira zodalirika, zosinthika, komanso zotsutsana ndi kusokoneza ma signal akutali.

RF over fiber Kufotokozera

Mndandanda wa R-ROFxxxxTRF pa fiber LinkUlalo wa analog Broadband Optical Transceiver ndi chipangizo chotumizira chakutali cha fiber optic chomwe chimapangidwira kuyeza zenizeni za DC kupita ku 1GHz ma siginecha amagetsi m'malo ovuta kwambiri amagetsi. Module yotumizira imakhala ndi 1 MΩ/50 Ω BNC yolowera, yomwe imatha kulumikizidwa ku zida zosiyanasiyana zowonera (ma probe apano, ma probe okwera kwambiri kapena zida zinazake zoyezera pafupipafupi). Mu gawo lopatsirana, chizindikiro chamagetsi cholowera chimasinthidwa ndikusinthidwa kukhala chizindikiro cha kuwala, chomwe chimatumizidwa ku gawo lolandila kudzera munjira imodzi yokha. Module yolandila imatembenuza chizindikiro cha kuwala kukhala chizindikiro chamagetsi. Kutumiza kwa chizindikiro cha kuwala kumayendetsedwa ndi kuwongolera kwamlingo wodziwikiratu kuti ukhalebe wolondola komanso wokhazikika, osakhudzidwa ndi kutayika kwa kuwala. Ma module onse a transceiver amathandizira mphamvu ya batri komanso kuwongolera kutali. Mpweya wotumizira wa kuwala umaphatikizansopo chosinthira chosinthika (1: 1/10: 1/100: 1) posintha mulingo wa siginecha wolandilidwa kuti muwongolere mawonekedwe osinthika. Kuphatikiza apo, chipangizocho chikapanda kugwiritsidwa ntchito, chimatha kulowetsedwa motalikirapo mumayendedwe ocheperako mphamvu kuti apulumutse mphamvu ya batri, ndipo chowunikira cha LED chikuwonetsa momwe ntchito ikugwirira ntchito.

Bandiwifi ya DC-500 MHZ/DC-1 GHZ ndiyosasankha

Adaptive kuwala kulowetsa chipukuta misozi

Kupindula kumasinthika ndipo mayendedwe osinthika amawongoleredwa

Imathandizira kuwongolera kwakutali ndipo imakhala yoyendetsedwa ndi batri, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito panja
