Abstract
An HDMI fiber-optic extender is for providing long-distance signal transmission between a signal transmitting device and a signal receiving device, and includes an HDMI optical transmitter and an HDMI optical receiver. The HDMI optical transmitter uses a tri-direction transmitter optical sub-assembly and a first tri-direction optical sub-assembly to convert HDMI signals (including three high-frequency data signals, a high-frequency clock signal, a low-frequency data signal and a low-frequency clock signal) received from the signal transmitting device into optical signals, and couples the optical signals onto a pair of single-core optical fibers of a fiber-optic assembly. The HDMI optical receiver uses a tri-direction receiver optical sub-assembly and a second tri-direction optical sub-assembly to convert the optical signals received from the fiber-optic assembly into the HDMI signals, and transmits the HDMI signals to the signal receiving device.
