Ibiranga by'ingenzi n'iterambere riherutse guterwa na Photodetector yihuta cyane

Ibiranga by'ingenzi n'iterambere rya vuba aha ryaicyuma gipima foto cyihuta cyane
Bitewe n'iterambere rya siyansi n'ikoranabuhanga, habayeho ikoreshwa rya Photodetector yihuta cyane (module yo gutahura imbonankubone) mu nzego nyinshi ni nyinshi cyane. Iyi nyandiko izagaragaza umuvuduko wo hejuru wa 10GImashini ipima foto(module detection module) ihuza photodiode yihuta cyane (APD) na amplifier y'urusaku ruto, ifite uburyo bumwe bwo kwinjiza fibre ivanze, SMA connector output, kandi ifite ubushobozi bwo kwinjiza, ubushobozi bwo kwinjiza, ubushobozi bwo kwinjiza AC, na flat gain.

Iyi module ikoresha InGaAs APD detector ifite spectral range ya 1100 ~ 1650nm, ikwiriye sisitemu yo kohereza fibre optique yihuta cyane no kumenya pulse yihuse cyane. Mu rwego rw'itumanaho ry'amajwi, ubushobozi bwo kumenya no kwihuta kwa photodetectors ni ibipimo by'ingenzi by'imikorere. Ubushobozi bwo kumenya amakuru menshi bwa module bugera kuri -25dBm kandi imbaraga zo gupima amakuru ni 0dBm, bigatuma amakuru yoherezwa neza mu gihe hari imbaraga nke za optique.
Byongeye kandi, module ihuza kandi na preamplifier na booster circuit, bishobora kugabanya urusaku neza no kunoza ikigereranyo cy'urusaku ku kimenyetso. Umusaruro wa AC uhujwe ushobora kugabanya ingaruka z'igice cya DC no kunoza ubwiza bw'ikimenyetso. Imiterere y'ubwiyongere bw'umuvuduko ituma module igira inyungu ihamye ku bunini bw'urumuri, birushaho kunoza ubwiza bw'ikimenyetso.
Mu rwego rwo gukoresha, iyi module ikoreshwa cyane cyane mu gupima umuvuduko w'amajwi, itumanaho ryihuse ry'ahantu hakoresha urumuri n'itumanaho ryihuse ry'urumuri. Uko ikoranabuhanga rigenda ritera imbere, abakeneye muri izi nzego nabo barimo kwiyongera. Kubwibyo, iterambere n'ikoreshwa ry'iyi module ni ingenzi cyane.
Imikorere n'ikoreshwa rya module bituma iba imwe mu zizwi cyaneibikoresho bigezweho byo gupima fotoku isoko muri iki gihe. Ifite imiterere yo gukora neza, ituze kandi yizewe cyane, kandi ishobora guhaza ibyifuzo by'ikoreshwa ry'amashami atandukanye. Mu iterambere ry'ejo hazaza, hamwe n'iterambere rihoraho ry'ikoranabuhanga no kwaguka guhoraho kw'amashami akoreshwa, module izakoreshwa cyane kandi itezwe imbere.
