CDMA 800MHz Fiber Optic Repeater SERIES
Brief Introduction:
CDMA Optical Fiber Repeater is the one transmitting the CDMA signals by optical
fibers, with five specifications of 1w, 2w, 5w, 10w, 20w.
It can be used as the signal resource for CDMA indoor cover system as well as for
other areas, such as area without signals, area where we cannot establish the wireless
repeater and area with bad environment for signal coverage.
Highlight Features
