Pambuyo pa mawonekedwe a optical module, kuyesa ntchito yake ndi sitepe yofunikira.Pamene zigawo za kuwala mu dongosolo lonse la intaneti zimaperekedwa ndi wogulitsa yemweyo, ngati dongosolo la intaneti likhoza kugwira ntchito bwino, palibe chifukwa choyesera padera zigawozikuluzikulu. a dongosolo.Chifukwa chake, kuyesa magawo a kuwala, makamaka magwiridwe antchito ndi kugwirizana kwa gawo lililonse la kuwala ndikofunikira.Ndiye mumayesa bwanji magwiridwe antchito a Optical module?
Optical module imapangidwa ndi transmitter ndi receiver.Pamene transmitter imagwirizanitsidwa ndi wolandira kudzera mu fiber optical, ngati chiwerengero cha zolakwika za dongosolo lonse sichikukwaniritsa zotsatira zomwe zikuyembekezeredwa, kodi ndi vuto la transmitter kapena vuto lolandira?The test Optical module nthawi zambiri imagawidwa m'magawo anayi, omwe amagawidwa m'mayesero a transmitter ndi wolandila.
Mayeso a Transmitter
Mukayesa, muyenera kulabadira kutalika kwa mawonekedwe ndi mawonekedwe a ma transmitter output waveform, komanso kulolerana kwa jitter ndi bandwidth ya wolandila.Poyesa transmitter, muyenera kulabadira mfundo ziwiri izi: Choyamba: Ubwino wa chizindikiro cholowera chomwe chimagwiritsidwa ntchito poyesa transmitter uyenera kukhala wabwino mokwanira. Kuphatikiza apo, miyeso yamagetsi iyenera kutsimikiziridwa ndi miyeso ya jitter ndi kuyeza kwa chithunzi cha diso.Kuyeza kwachithunzi cha diso ndi njira yodziwika bwino yowonera mawonekedwe a ma waveform a transmitter chifukwa chojambula chamaso chili ndi chidziwitso chochuluka chomwe chikuwonetsa momwe makinawo amagwirira ntchito.
Chachiwiri: Chizindikiro chotulutsa chowulutsira chiyenera kuyezedwa ndi zisonyezo zowoneka bwino monga kuyesa kwa chithunzi cha diso, mawonekedwe owoneka bwino komanso chiŵerengero cha kutha.
Mayeso olandila
Poyesa wolandila, muyeneranso kulabadira mfundo ziwiri izi:
Choyamba: Mosiyana ndi chotumizira mayeso, mtundu wa chizindikirocho uyenera kukhala wosauka mokwanira poyesa wolandila.Chifukwa chake, chojambula chamaso chopepuka choyimira chizindikiro choyipa kwambiri chiyenera kupangidwa.Chizindikiro choyipitsitsachi chiyenera kudutsa jitter.Kuyeza ndi kuyesa mphamvu ya kuwala kumagwiritsidwa ntchito poyesa.
Chachiwiri: Pomaliza, muyenera kuyesa chizindikiro chamagetsi cha wolandila.Pali mitundu itatu yayikulu ya mayeso:
Kuyesa kwazithunzi zamaso: Izi zimatsimikizira kuti "maso" a chithunzi cha diso ali otseguka.Kuyesa kwachithunzi chamaso nthawi zambiri kumatheka ndi kuya kwa kuchuluka kwa zolakwika pang'ono
Mayeso a Jitter: yesani mitundu yosiyanasiyana ya ma jitter
Kulondolera kwa Jitter ndi kulolerana: Yesani kutsatira jitter ndi dera lamkati lobwezeretsa wotchi
Gawo loyesera lopepuka ndi ntchito yovuta, komanso ndi gawo lofunikira kuti liwonetsetse kuti likugwira ntchito.Monga njira yoyezera yomwe imagwiritsidwa ntchito kwambiri, kuyeza kwa chithunzi chamaso kumatha kuyesa bwino emitter ya module ya optical.Mayeso olandila a module ya optical ndizovuta kwambiri ndipo amafuna njira zambiri zoyesera.
