I-Avalanche photodetector: Ithwebula izimpawu zokukhanya okucacile

Isitholi sesithombe se-Avalanche: Ibamba izimpawu zokukhanya okucacile

I-data torrent engu-10Gb ngomzuzwana idlula kuma-optical fibers. Ama-optical signals abuthakathaka afana nezimpukane olwandle olujulile. Angabanjwa kanjani futhi akhuliswe ngokunembile? I-Rofea Optoelectronics' esanda kwethulwa i-ROF-APR 10G high-speed Avalanche photodetector module iyisisombululo esiyinhloko sale nkinga. Akuyona nje i-receiver kodwa "i-amplifier" enamandla yama-optical signals, eklanyelwe ngqo ukunqoba imikhawulo yokuthola ama-optical signals asheshayo.

✅ Ingqimba yeqhwa elisheshayo: Impendulo yesivinini esiphezulu eyakhelwe ngaphakathii-photodiode yeqhwa(i-APD photodiode), njengomzingeli wezithombe obukhali, ibangela "umphumela we-avalanche" ngaphansi kwezibonakaliso zokukhanya ezibuthakathaka, okufeza ukuphindaphindwa kabili kwesibonakaliso sokuqala.

✅ Ukukhulisa okunembile komsindo ophansi: I-amplifier ehlanganisiwe yomsindo ophansi iqinisekisa ukuthi isignali igcina isilinganiso esiphezulu sesignali-kuya-kumsindo ngesikhathi sokukhulisa, ngemininingwane ecacile nehlukanisayo.

✅ Ukufinyelela okuguquguqukayo: Kokubili okokufaka kwefayibha yemodi eyodwa kanye neyemodi eminingi kungaphathwa kalula, futhi umphumela wesixhumi esibonakalayo se-SMA uxhumeka futhi udlale, okwenza kube lula ukuhlanganiswa ohlelweni lwakho.

✅ Ukusebenza okuvelele: ukutholakala okuphezulu kanye nokuzwela okuphezulu kuqinisekisa ukuthi amasignali abuthakathaka awanandawo yokucasha; Izici zokukhishwa okuhlanganisiwe kwe-AC kanye nokutholakala kwe-gain flat zinikeza isisekelo esiqinile sokucutshungulwa okulandelayo.

Incazelo Yomkhiqizo

I-ROF-APR-10G photodetector yesivinini esikhulu seqhwa (Isitholi sezithombe se-APD) ihlanganisa i-photodiode ye-avalanche yokuphendula ngesivinini esikhulu (i-APD photodiode) kanye ne-amplifier yomsindo ophansi, okokufaka kwe-fiber-coupled yemodi eyodwa/yemodi eminingi, kanye nokukhipha kwesixhumi se-SMA. Ifaka i-gain ephezulu, ukuzwela okuphezulu, ukuphuma kwe-AC-coupled, kanye ne-flat gain. Isetshenziswa kakhulu ezinhlelweni zokudlulisa i-fiber ye-optical yesivinini esikhulu kanye nokutholwa kwe-pulse ye-optical yesivinini esikhulu kanye neminye imikhakha.

Izici zomkhiqizo:

Ububanzi be-Spectral: 1100-1650nm

Isitholi se-InGaAs APD

Ukuzwela okuphezulu: -26 DBM

Amandla okukhanya agcwele yi-1dBm

Ihlanganisa i-preamplifier kanye nesekethe yokukhulisa

Izinkambu zohlelo lokusebenza:

Ukutholwa kwe-pulse yesivinini esiphezulu

Ukuxhumana kwe-optical kwesikhala esisheshayo

Ukuxhumana ngefayibha ye-optical esheshayo

Kwa-Rofea Optoelectronics, sinikeza izinhlobo ezahlukene zemikhiqizo ye-electro-optic ukuze ihlangabezane nezidingo zakho, okuhlanganisa i-modulator ye-electro-optic yezentengiselwano, imithombo ye-laser, i-photodetector, ama-amplifiers optical, nokuningi.
Umkhiqizo wethu ubonakala ngokusebenza kwawo okuhle kakhulu, ukusebenza kahle okuphezulu, kanye nokuguquguquka. Siyaziqhenya ngokunikeza izinketho zokwenza ngokwezifiso ukuze kuhlangatshezwane nezicelo ezihlukile, ukunamathela ezimisweni ezithile, kanye nokunikeza isevisi ekhethekile kumakhasimende ethu.
