ʻO nā hiʻohiʻona nui a me ka holomua hou o ka Photodetector kiʻekiʻe

ʻO nā hiʻohiʻona nui a me ka holomua hou okiʻekiʻe wikiwiki Photodetector
Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ka noi ʻana o ka wikiwiki kiʻekiʻe Photodetector (module ʻike maka) ma nā kahua he nui a ʻoi aku ka laulā. E hoʻolauna kēia pepa i kahi 10G kiʻekiʻe-wikiwikiMea ʻike kiʻi(mode ʻike maka) e hoʻohui i kahi kiʻi kiʻi avalanche pane kiʻekiʻe (APD) a me kahi mea hoʻonui haʻahaʻa haʻahaʻa, loaʻa kahi hoʻokomo hoʻokahi mode/multi-mode fiber i hui pū ʻia, puka mea hoʻohui SMA, a loaʻa ka waiwai kiʻekiʻe, ʻike kiʻekiʻe, AC hui pū ʻia. , a loaa palahalaha.

Hoʻohana ka module i ka InGaAs APD detector me kahi spectral range o 1100 ~ 1650nm, i kūpono no nā ʻōnaehana hoʻoili fiber optical kiʻekiʻe a me ka ʻike pulse optical kiʻekiʻe. Ma ke kahua o ka kamaʻilio optical, ʻo ka naʻau a me ka wikiwiki o nā photodetectors he mau hōʻailona hana koʻikoʻi. ʻO ka sensitivity kiʻekiʻe o ka module hiki i -25dBm a ʻo ka mana optical saturation he 0dBm, e hōʻoiaʻiʻo ana i ka lawe ʻana i ka ʻikepili ma lalo o nā kūlana mana optical haʻahaʻa.
Eia kekahi, hoʻohui pū ka module i kahi preamplifier a me booster circuit, hiki ke hoʻohaʻahaʻa maikaʻi i ka walaʻau a hoʻomaikaʻi i ka hōʻailona noise ratio. Hiki i ka AC hui pū ʻia ke hōʻemi i ka mana o ka mea DC a hoʻomaikaʻi i ka maikaʻi o ka hōʻailona. ʻO ke ʻano o ka loaʻa ʻana o ka flatness e hiki ai i ka module ke loaʻa ka loaʻa paʻa i nā lōʻihi hawewe he nui, e hoʻonui hou i ka maikaʻi o ka hōʻailona.
Ma ke kahua o ka noi, hoʻohana nui ʻia ka module i ka ʻike ʻana i ka pulse kiʻekiʻe, ke kamaʻilio ākea ākea ākea a me ke kamaʻilio fiber optical kiʻekiʻe. Me ka hoʻomohala ʻana o ka ʻenehana, ke hoʻonui nei ka makemake i kēia mau ʻāina. No laila, he mea nui ka hoʻomohala ʻana a me ka hoʻohana ʻana i kēia module.
ʻO ka hana a me ka hoʻohana ʻana o ka module e hana ia i kekahi o nā mea nui loanā mea nānā kiʻi kiʻi kiʻi kiʻima ka makeke i keia la. Loaʻa iā ia nā hiʻohiʻona o ka hana kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me ka hilinaʻi kiʻekiʻe, a hiki ke hoʻokō i nā pono noi o nā kahua like ʻole. I ka hoʻomohala ʻana i ka wā e hiki mai ana, me ka holomua mau o ka ʻenehana a me ka hoʻonui mau ʻana o nā kahua noi, e hoʻohana nui ʻia ka module a hoʻolaha ʻia.
