Product Description

Apply to VHF interphone communication system and trunking communication system signal coverage extension. This is also known as “VHF Fiber Optic BDA”.

Product Features：
☞One Donor Unit can link 4 Remote Units at most
☞Adopting Wavelength Division Multiplexing technology to realize long distance transmission via a fiber
☞Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
☞Details repeater parameters and status monitor, such as RSSI, temperature, output power level, gain, ATT, return loss, VSWR etc.
☞Configure RS-232 ports to links to laptop for local test
☞ Monitor the Remote Unit via Donor Unit.
☞Can choose SMS, GPRS or TCP/IP for remote monitoring.
