Description
Our AHD Video over Fiber Converters can simultaneously transmit 1-8 channels AHD over one multimode or single-mode optical fiber. Electronic and optical adjustments are never required. LED indicators are provided for instantly monitoring system status. Devices are available for either standalone or rack-mount installation,
which is suitable for different working environment. Compatible with AHD-H, AHD-M, AHD-L. Lossless non-compression real time transmission.
Its optical module and core circuit adopt the imported components that have high stability, and all optical & electrical interfaces conform to the international standards, which is applied to the different working environment. This optical transceiver with video status indication can monitor the normal operation of system.
