Chithunzi Chojambulidwa cha LC/UPC Chachimuna ndi Chachikazi Choteteza

LC/UPC Attenuator ya Amuna ndi Akazi

Kufotokozera Kwachidule:

● Kutalika kwa Mafunde Kodziyimira Payokha

● Kuthamanga kochepa

● Kukhazikika kwabwino kwa chilengedwe

● Kapangidwe kovomerezeka kopitilira 200mW mosalekeza

● Mphamvu yogwiritsira ntchito mphamvu popanda kuwonongeka kwa magwiridwe antchito

● Kuwunikira kumbuyo kumawoneka bwino mpaka < -55dB

● Ya UPC ndi < -60dB ikupezeka ya APC

● Kusamva kugawanika kwa ma polarization

Ma DOWELL Attenuators ndi oyenerera kugwiritsa ntchito njira yolumikizirana ndi sitima zapamadzi.

Ma DOWELL Singlemode Attenuators amapangidwa ndi Build Out Process kuti apeze kukhazikika kwabwino pakugwira ntchito komanso malo ogwirira ntchito odziyimira pawokha kuti akhale ndi kubwerezabwereza komanso kufanana kwabwino.

Ukadaulo wokhala ndi patent umayang'ana kwambiri pa ulusi wonse wochepa komanso zotsatira zabwino kwambiri zopukuta kuti zikhale zabwino kwambiri pankhani ya kugwedezeka kochepa, palibe kukanda kooneka, ming'alu, ming'alu, zipsera kapena mabowo pansi pa 400X DORC, komanso zapadera zomwe RL< -55 pa dB iliyonse.

Timapereka 1 ~ 20 dB ndi miyeso yokhazikika ya attenuation pa 3, 5, 10, 15 ndi 20 dB, zomwe zimapangitsa kuti pakhale kuchuluka kwa zinthu zomwe zingagwiritsidwe ntchito popanga zinthu zambiri komanso kuti attenuation ikhale yogwirizana ndi zosowa zanu, mothandizidwa ndi gulu lathu laukadaulo kuti tipeze mgwirizano wabwino kwambiri.
