    The HR-731 is a kit of Sender and Receiver modules to extend HDMI and bi-directional RS-232 up to 1 Km (3280 ft) on a single (simplex) multi-mode fiber optic cable (uses SC connector).

    The unit is fully HDCP compliant and supports HDMI 1.4 deep-color and 3D. EDID pass-through from the remote display to the source guarantees trouble free operation. Virtually all PC (DVI) and HDTV resolutions are supported.

    The Sender / Receiver modules are housed in sturdy and compact metal enclosures and include surface mounting provisions.

    Please Note: Both the Sender HR-731-S and the Receiver HR-733-R use a single SC connector and require a
    multi-mode fiber-optic cable. The extender is not compatible with single-mode cables.
