Iimpawu eziphambili kunye nenkqubela phambili yakutshanje yeisantya esiphezulu seFotodetector
Ngophuhliso lwesayensi kunye netekhnoloji, ukusetyenziswa kweFotodetector yesantya esiphezulu (imodyuli yokubona amehlo) kwiinkalo ezininzi lubanzi ngakumbi.Eli phepha liza kwazisa i-10G yesantya esiphezuluIsikhangeli seefoto(imodyuli yokubona imodyuli) edibanisa i-avalanche photodiode ephendula ngesantya esiphezulu (APD) kunye nesandisi-lizwi esisezantsi, sinemowudi enye/imodyuli yefiber edityanisiweyo, isiphumo sesidibanisi se-SMA, kwaye inenzuzo ephezulu, ubuntununtunu, imveliso edityanisiweyo ye-AC. , kunye nenzuzo ethe tyaba.
Imodyuli isebenzisa i-InGaAs APD detector kunye ne-spectral range ye-1100 ~ 1650nm, efanelekileyo kwiinkqubo ze-high-speed optical fiber transmission kunye ne-high-speed optical pulse monitoring.Kwintsimi yonxibelelwano lwe-optical, uvakalelo kunye nesantya se-photodetectors zizibonakaliso zokusebenza ezibalulekileyo.Uvakalelo oluphezulu lwemodyuli lufikelela kwi-25dBm kwaye amandla optical saturation yi-0dBm, ukuqinisekisa ukuhanjiswa kwedatha ethembekileyo phantsi kweemeko zamandla aphantsi optical.
Ukongeza, imodyuli iphinda idibanise i-preamplifier kunye nesekethe ye-booster, enokunciphisa ngokufanelekileyo ingxolo kunye nokuphucula isignali kumlinganiselo wengxolo.Imveliso edibeneyo ye-AC inokunciphisa impembelelo yecandelo le-DC kunye nokuphucula umgangatho womqondiso.Uphawu lokuzuza umtyaba lwenza ukuba imodyuli ibe nenzuzo ezinzileyo kumaza amaza amaninzi, iphucula ngakumbi umgangatho wesiginali.
Kwintsimi yesicelo, imodyuli isetyenziselwa ukukhangela i-pulse ye-high-speed, i-high-speed space optical communication kunye ne-high-speed optical fiber communication.Ngophuhliso lwetekhnoloji, imfuno kula macandelo iyanda.Ke ngoko, uphuhliso kunye nokusetyenziswa kwale modyuli kubaluleke kakhulu.
Ukusebenza kwemodyuli kunye nokusetyenziswa kwayo kuyenza ibe yenye yezona zibalaseleyoii-photodetectors eziphambilikwimarike namhlanje.Ineempawu zokusebenza okuphezulu, ukuzinza okuphezulu kunye nokuthembeka okuphezulu, kwaye inokuhlangabezana neemfuno zesicelo semimandla eyahlukeneyo.Kuphuhliso lwexesha elizayo, kunye nenkqubela phambili yetekhnoloji kunye nokwandiswa okuqhubekayo kwemimandla yesicelo, imodyuli iya kusetyenziswa ngokubanzi kwaye ikhuthazwe.
