SC/UPC Wothandizira Amuna ndi Akazi
Kanema wa Zamalonda
Kufotokozera
DOWELL Attenuators ndi oyenerera pamayendedwe apanyanja apamadzi.
DOWELL Singlemode Attenuators amapangidwa ndi Build Out Process kuti akhazikike bwino pogwira ntchito komanso makina opangira makina kuti akhale obwerezabwereza komanso ofanana.
Ukadaulo wapatent umayang'ana pa ulusi wonse wocheperako & zotsatira zabwino zopukutira zamtundu wabwino molingana ndi kutsika kocheperako, kosawoneka bwino, ming'alu, tchipisi, zilema kapena maenje pansi pa 400X DORC, komanso zapadera zomwe RL< -55 pamtengo uliwonse wa dB.
Timapereka 1 ~ 20 dB ndi ma attenuation okhazikika pa 3, 5, 10, 15 ndi 20 dB, kutukuka kwachuma kuti pakhale zokolola zambiri komanso kutsika kopangidwa mwamakonda kukwaniritsa zomwe mukufuna, mothandizidwa ndi gulu lathu laukadaulo kuti mupeze mgwirizano wabwino kwambiri. .
