Mapulogalamu Atsopano aChowunikira Zithunzi Chachangu Kwambiri
Kuwala, kowala kwambiri kotero kuti kumakhala kosaoneka, komabe kumatsimikiza momwe kulumikizana kwamtsogolo kudzayendera… Mu dziko la gigabit komwe zizindikiro za kuwala zimadutsa kulikonse, kuchedwa kulikonse kwa nanosecond kungatanthauze kutayika kwa deta yofunika kwambiri. Kuzindikira kuthamanga kwa kuwala kwa liwiro lalikulu, machitidwe olumikizirana a 43Gbit/s, maulalo a microwave photonic… Magawo amakono awa nthawi zonse amafunsa kuti: Kodi pali njira yodziwira ya optoelectronic yomwe imaphatikiza kukhudzidwa kwakukulu kwambiri ndi kuyankha mwachangu kwambiri?
Masiku ano, gulu la ROF-PT la ma amplifting a high speed amplifting lapangidwa.chowunikira zithunziMa modules apereka yankho lomveka bwino komanso lodalirika.
Mwa kuphatikiza mozama liwiro lapamwambaZipangizo zozindikira ma PINNdi ma chips enieni a TIA amplification, tapanga ulalo wathunthu wokonzera ma signal kuyambira polowera kupita potuluka. Kulumikizana kwa ulusi wa single-mode kumaonetsetsa kuti ma signal input oyera, ma K connectors amapeza ma output okhazikika komanso ogwira mtima, ndipo bandwidth yofika pa 40GHz ndi nthawi yoyankha yosakwana 10ps zimapangitsa kuti njira ya optical signal isabisike. Kaya ndi kujambulidwa kwakukulu kwa 1200-1650nm spectral range kapena kulinganiza kwa high gain, high sensitivity ndi gain flatness, mndandanda wa ROF-PT nthawi zonse umayesetsa kupeza bwino pakati pa liwiro ndi kulondola.
Poyang'anizana ndi zofunikira kwambiri za ROF microwave link system kapena vuto la ma signature ofooka mu Brillouin sensing, ingathandizenso kutulutsa kosiyana komwe kumapangidwa mwamakonda, zomwe zimathandiza kuti igwirizane mosavuta ndi kapangidwe kake kapamwamba.
Kukulitsa kwa liwiro la ROF-PT mndandanda wa ROF-PTchowunikira chamagetsiModuleyi imapatsa mainjiniya njira yothandiza komanso yodalirika, zomwe zimawathandiza kuti azitha kugwira ntchito zovuta zozindikira zizindikiro za kuwala mofatsa komanso molimba mtima. Iyi si module yokha; komanso ndi maziko a magwiridwe antchito aukadaulo wamtsogolo wa kuwala - apa, njira yowunikira imajambulidwa bwino, ndipo liwiro limafotokozedwa bwino ndi ife.

Mafotokozedwe Akatundu:
Chojambulira cha ROF-PT chapamwamba kwambiri chimaphatikiza chowunikira cha PIN chapamwamba kwambiri ndi chip ya TIA amplification. Chili ndi cholumikizira cha single-mode fiber ndi cholumikizira cha K. Chili ndi gain yapamwamba, sensitivity yapamwamba, AC coupling output, ndi flat gain characteristics. Chotulutsa chosiyana chomwe chimapangidwa mwamakonda chimapezeka. Chimagwiritsidwa ntchito makamaka mumakina otumizira ma fiber optical achangu kwambiri, ROF, ndi makina owonera ma fiber optical, ndi zina zotero.
Zinthu zomwe zili mu malonda:
Mtundu wa Spectral: 1200 - 1650 nm
Bandwidth: 10 GHz, 20 GHz, 40 GHz
Nthawi yoyankha: Yochepera 10 ps
