Hunhu hukuru uye kufambira mberi kwazvino kwePhotodetector inomhanya zvikuru
Nekuvandudzwa kwesainzi netekinoroji, kushandiswa kwePhotodetector inokurumidza (module yekuona maziso) munzvimbo dzakawanda yakakura zvikuru. Pepa rino richaunza 10G inokurumidza zvikuruChinoongorora mufananidzo(optical detection module) inobatanidza high-speed response avalanche photodiode (APD) uye low noise amplifier, ine single mode/multi-mode fiber coupled input, SMA connector output, uye ine high gain, high sensitivity, AC coupled output, uye flat gain.
Module iyi inoshandisa InGaAs APD detector ine spectral range ye1100~1650nm, iyo yakakodzera masisitimu ekutumira mafiber emagetsi anomhanya nekukurumidza uye high-speed optical pulse detection. Mundima yekutaurirana kwemaziso, kunzwisisika nekumhanya kwema photodetectors zviratidzo zvakakosha zvekushanda. Kunzwa kwakanyanya kwemodule kunosvika -25dBm uye simba re saturation optical i0dBm, zvichiita kuti data ritumirwe zvakanaka pasi pesimba remagetsi rakaderera.
Pamusoro pezvo, module iyi inobatanidzawo preamplifier ne booster circuit, izvo zvinogona kuderedza ruzha zvinobudirira uye kuvandudza ratio yesignal kune noise. AC coupled output inogona kuderedza simba reDC component uye kuvandudza mhando yesignal. Hunhu hwe gain flatness hunoita kuti module ive ne stable gain pa multiple wavelengths, zvichiwedzera kugadzirisa kunaka kwesignal.
Mubasa rekushandisa, module iyi inonyanya kushandiswa mukuona pulse nekukurumidza, kutaurirana kwemaziso munzvimbo nekukurumidza uye kutaurirana kwefiber yemagetsi nekukurumidza. Nekuvandudzwa kwetekinoroji, kudiwa kwenzvimbo idzi kuri kuwedzerawo. Saka, kugadzirwa nekushandiswa kwemodule iyi kwakakosha zvikuru.
Mashandiro emodule iyi uye mashandisirwo ayo zvinoita kuti ive imwe yeanonyanya kukosha.michina yekuongorora mifananidzo yepamusoroiri pamusika nhasi. Ine hunhu hwekushanda kwepamusoro, kugadzikana kwakanyanya uye kuvimbika kwakanyanya, uye inogona kusangana nezvinodiwa zvekushandisa muminda yakasiyana. Mukuvandudzwa kweramangwana, nekufambira mberi kwetekinoroji uye kuwedzera kuri kuramba kuchiitwa kweminda yekushandisa, module iyi ichashandiswa zvakanyanya uye ichakurudzirwa.
