2 Channel 1080P AHD Fiber Optical Video Converter BNC to fiber video converter with RS485/RS232/RS422 data optical
Overview
AHD coaxial HD optical transceiver can convert the HD videos scanned line by line into optical signals by the
use of analog modulation technology in accordance with the coaxial cable-based HD video transmission
specifications. Due to the adoption of PFM modulation technology, its transmission range can exceed 20Km. As an
upgraded product in the analogue monitoring technology architecture, it is still a closed-type analogue monitoring
system. Two-way transmission of image and data signals can be realized in an optical fiber based on the use of
wavelength division multiplexing technology, to meet the actual demand of monitoring project. It is widely used in such
HD monitoring systems as remote expressway and railway monitoring system, bank and school.
