Kev piav txog
Dowell hostrenators yog tsim nyog rau submarine networking system.
Dowell Singlemode cov delentreators yog tsim los ntawm kev tsim tawm cov txheej txheem kom tau txais kev ua haujlwm zoo thiab muaj kev siv tshuab ua kom muaj cov kev ua haujlwm zoo dua & kev sib dhos.
Kev siv thev naus laus zis ua rau muaj fiber ntau & zoo meej polution kev kho kom zoo, tawg, tawg, thiab tshwj xeeb uas rl <-55 rau txhua tus nqi DB.
Peb muab 1 ~ 20 dB thiab cov qauv kev ua raws li qhov tseem ceeb ntawm 3, 5, 15 thiab 20 pab pawg ua haujlwm tau txais kev pab thiab txhawb nqa los ntawm peb cov pab pawg ua kom tau txais cov synergy zoo tshaj plaws.
