HDMI (High-Definition Multimedia Interface) recently has become increasingly popular in the application of video and audio transmission system. In view of the extreme of electrical performances, however, the traditional copper wire cable imposes limits on signal transmission distance and signal quality. In reality, optical fiber is of low dispersion, which in turn has the strength of longer signal transmission distance and better signal transmission quality in comparison to the traditional copper wire cable. Smartopcom DVI/HDMI extender uses 2 cores fiber without any copper wire inside, where radio frequency interference phenomenon is literally ruled out, which shows the advantage of high performance and good signal quality as well as low cost.


High Performance — The HFX-2100 series is a high performance 4K Optical Extender that transmits high resolution DVI / HDMI signals over extreme distances using 2 cores fiber.  This extender supports HDMI v1.4(non-HDCP) signals with resolutions up to 4K (4096×2160 / 30p) over cable distances up to 60Km(According to the SFP+ Transceivers and fiber).


Fiber Optic Extension — The extender set consists of an optical transmitter module that converts the DVI / HDMI signals into light pulses for transmission over a single strand of Multi-Mode or Single-Mode optical fiber cable. An optical receiver module converts the light pulses back to a DVI / HDMI signal for display on a monitor or projector. The SENDER unit includes an internal EDID memory that can acquire and store the EDID from any display.


Cutting-Edge Optics — Most single-fiber optical extenders transmit signals over multiple optical wavelengths, which can suffer from chromatic dispersion over long cable runs.  To avoid this issue, this extender employs a cutting-edge, high-speed SerDes that combines the DVI / HDMI signal channels into a single uncompressed 10.3 Gbps bit stream.  This enables the optical transmission of the signal over a single optical wavelength, which provides increased signal fidelity, stability and flawless image quality, regardless of cable length.  These features make the HFX-2100 series the ideal future-proof choice for systems designers and integrators who need to transmit high resolution DVI / HDMI signals over extreme distances.
