The DVI-7340 and DVI-7341 from DVIGear are 4K optical extenders designed for demanding system requirements. Each extender set consists of an optical transmitter module that converts the AV signals into light pulses for transmission over a single strand of multimode or single-mode optical fiber cable. An optical receiver module converts the light pulses back to AV signals for the display as well as other downstream devices. The units handle cable distances of up to 1,000ft. (300m) with or without HDCP. In applications where HDCP compliance is not required, optical links up to 1.2 miles are supported. The extenders manage multiple signals such as uncompressed HDMI or DVI, embedded audio, balanced or unbalanced external audio, bidirectional IR, RS-232, and ethernet using a single fiber optic cable. Managing HDMI with embedded audio as well as independently routed balanced audio signal extension, they support resolutions up to 4K (UHD), and offer three EDID modes.
