Isi njirimara na ọganihu ọhụrụ nkefotodetector dị elu
Site na mmepe nke sayensị na teknụzụ, ngwa ngwa Photodetector dị elu (modul nchọpụta anya) n'ọtụtụ ebe na-abawanye ụba.Akwụkwọ a ga-ewebata ọsọ ọsọ 10GOnye nyocha foto(modul nchọpụta ngwa anya) nke na-ejikọta nzaghachi ngwa ngwa avalanche photodiode (APD) na ụda ụda dị ala, nwere otu mode / multi mode fiber tinyere ntinye, ntinye njikọ SMA, ma nwee nnukwu uru, nnukwu uche, mmepụta AC jikọtara ọnụ. , na uru dị larịị.
The modul na-eji InGaAs APD detector na a spectral nso nke 1100 ~ 1650nm, nke kwesịrị ekwesị maka elu-ọsọ ngwa anya fiber nnyefe usoro na elu-ọsọ ngwa anya pulse nchọpụta.N'ihe gbasara nkwurịta okwu anya, uche na ọsọ nke fotodetector bụ ihe ngosi arụmọrụ dị oke mkpa.Mmetụta dị elu nke modul ahụ ruru -25dBm na ike anya saturation bụ 0dBm, na-eme ka nnyefe data a pụrụ ịdabere na ya n'okpuru ọnọdụ ike anya dị ala.
Na mgbakwunye, modul na-ejikọta preamplifier na sekit booster, nke nwere ike belata mkpọtụ nke ọma ma melite mgbama na oke mkpọtụ.Mmepụta jikọtara AC nwere ike ibelata mmetụta nke akụrụngwa DC ma melite ogo mgbaàmà.Njirimara ewepụghị uru na-enyere modul ahụ aka inwe uru kwụsiri ike n'ọtụtụ wavelengths, na-eme ka ogo mgbama na-abawanye.
Na ngalaba nke ngwa, modul na-bụ-eji na elu-ọsọ usu nchọpụta, elu-ọsọ oghere ngwa anya na elu-ọsọ ngwa anya eriri nkwurịta okwu.Site na mmepe nke teknụzụ, ihe ndị a na-achọ na mpaghara ndị a na-abawanye.Ya mere, mmepe na ntinye nke modul a dị oke mkpa.
Ọrụ modul na ngwa na-eme ka ọ bụrụ otu n'ime ihe kachasịihe nchọpụta foto dị elun'ahịa taa.Ọ nwere njirimara nke arụmọrụ dị elu, nkwụsi ike dị elu na ntụkwasị obi dị elu, ma nwee ike izute mkpa ngwa nke ubi dị iche iche.N'ọdịnihu mmepe, na-aga n'ihu na nkà na ụzụ na-aga n'ihu na mgbasawanye nke ngwa ngwa, modul ga-eji ọtụtụ ebe ma kwalite.
