Cov Yeeb Yaj Kiab Txog Khoom
Kev piav qhia
DOWELL Attenuators tsim nyog rau submarine networking system.
DOWELL Singlemode Attenuators yog tsim los ntawm Build Out Process kom tau txais kev ruaj khov ua haujlwm zoo heev thiab chaw ua haujlwm tsis siv neeg kom muaj kev rov ua dua zoo dua & kev sib xws.
Cov thev naus laus zis patented tsom mus rau txhua qhov fiber attenuated & cov txiaj ntsig zoo meej polishing kho rau qhov zoo hauv cov nqe lus ntawm qis ripple, tsis pom khawb, tawg, chips, blemishes lossis qhov hauv qab 400X DORC, thiab tshwj xeeb uas RL <-55 rau txhua tus nqi dB.
Peb muab 1 ~ 20 dB thiab tus qauv attenuation tus nqi ntawm 3, 5, 10, 15 thiab 20 dB, qhov zoo ntawm kev lag luam rau kev muab khoom loj thiab kev cai attenuation tus nqi ua tau raws li koj qhov xav tau tshwj xeeb, txhawb nqa los ntawm peb pab neeg kev tshaj lij kom tau txais qhov zoo tshaj plaws synergy.
