Iimpawu eziphambili kunye nenkqubela phambili yakutshanjeiPhotodetector ekhawulezayo
Ngophuhliso lwesayensi netekhnoloji, ukusetyenziswa kwe-Photodetector ekhawulezayo (imodyuli yokubhaqwa kokukhanya) kwiindawo ezininzi ibanzi ngakumbi nangakumbi. Eli phepha liza kwazisa i-10G ekhawulezayoIsixhobo sokubona iifoto(imodyuli yokubona optical) edibanisa i-photodiode ye-avalanche yempendulo ekhawulezayo (i-APD) kunye ne-amplifier yengxolo ephantsi, ine-single mode/multi-mode fiber coupled input, i-SMA connector output, kwaye ine-gain ephezulu, i-high sensitivity, i-AC coupled output, kunye ne-flat gain.
Le modyuli isebenzisa i-InGaAs APD detector enoluhlu lwe-spectral lwe-1100 ~ 1650nm, efanelekileyo kwiinkqubo zokudlulisa i-optical fiber ezikhawulezayo kunye nokufunyanwa kwe-optical pulse ekhawulezayo. Kwicandelo lonxibelelwano lwe-optical, uvakalelo kunye nesantya se-photodetectors zizibonakaliso ezibalulekileyo zokusebenza. Uvakalelo oluphezulu lwe-module lufikelela kwi--25dBm kwaye amandla e-saturation optical yi-0dBm, okuqinisekisa ukuhanjiswa kwedatha okuthembekileyo phantsi kweemeko zamandla e-optical aphantsi.
Ukongeza, imodyuli ikwadibanisa i-preamplifier kunye ne-booster circuit, enokunciphisa ingxolo ngempumelelo kwaye iphucule umlinganiselo wesignali kwingxolo. Imveliso edibeneyo ye-AC inokunciphisa impembelelo yecandelo le-DC kwaye iphucule umgangatho wesignali. Uphawu lwe-gain flatness luvumela imodyuli ukuba ibe ne-gain ezinzileyo kwii-wavelengths ezininzi, nto leyo ephucula ngakumbi umgangatho wesignali.
Kwintsimi yesicelo, le module isetyenziswa kakhulu ekufumaneni i-pulse ngesantya esiphezulu, unxibelelwano lwe-optical space olukhawulezayo kunye nonxibelelwano lwe-optical fiber olukhawulezayo. Ngophuhliso lwetekhnoloji, imfuno kwezi ndawo nayo iyanda. Ke ngoko, uphuhliso kunye nokusetyenziswa kwale module kubaluleke kakhulu.
Ukusebenza kwemodyuli kunye nokusetyenziswa kwayo kuyenza ibe yenye yezona zibalaseleyoizixhobo zokubona iifoto eziphambiliikwimarike namhlanje. Ineempawu zokusebenza okuphezulu, ukuzinza okuphezulu kunye nokuthembeka okuphezulu, kwaye inokuhlangabezana neemfuno zesicelo seenkalo ezahlukeneyo. Kwixesha elizayo, ngenkqubela phambili yetekhnoloji kunye nokwandiswa okuqhubekayo kweenkalo zesicelo, le module iya kusetyenziswa kwaye ikhuthazwe ngakumbi.
