Kev piav qhia
DOWELL Attenuators yog tsim nyog rau submarine networking system.
DOWELL Singlemode Attenuators yog tsim los ntawm Tsim Tawm Txheej Txheem kom tau txais kev ua haujlwm ruaj khov thiab ua haujlwm siab ua haujlwm kom muaj kev rov ua tau zoo dua & sib xws.
Patented thev naus laus zis tsom rau txhua qhov kev sib tw fiber ntau & zoo meej polishing tau txais txiaj ntsig zoo rau qhov zoo ntawm qhov tsis tshua muaj ripple, tsis pom khawb, tawg, chips, blemishes lossis pits nyob rau hauv 400X DORC, thiab tshwj xeeb uas RL< -55 rau ib qho nqi dB.
Peb muab 1 ~ 20 dB thiab tus qauv attenuation qhov tseem ceeb ntawm 3, 5, 10, 15 thiab 20 dB, ua kom muaj txiaj ntsig kev lag luam rau cov khoom tsim khoom loj thiab tus nqi tsim nyog ua kom tau raws li koj qhov kev xav tau tshwj xeeb, txhawb nqa los ntawm peb pab neeg ua haujlwm kom tau txais kev sib koom ua ke zoo tshaj plaws .
