Abstract: Aspects of the subject disclosure may include, for example, a device that encodes digital signals representing image data captured by a video camera and provided according to a 4K ultra-high definition (4K-UHD) standard. The digital signals are transmitted as serial digital interface (SDI) streams to a wavelength-division multiplexing (WDM) unit; the WDM unit performs electrical-to-optical conversion of the SDI streams and outputs a multiplexed signal to a single fiber-optic cable. The video camera, encoding unit, and WDM unit form a combined module within a housing; the device connects to a proximal end of a single fiber-optic cable, and a distal end of the single fiber-optic cable is configurable for connection to a demultiplexer of a 4K-UHD video presentation device. The multiplexed signal is transmitted on the single fiber-optic cable unidirectionally from the proximal end to the distal end. Other embodiments are disclosed.
