The HDMI20-OPTC-TX/RX220-Pro is a HDMI 2.0 compatible, HDCP 2.2 compliant extender pair for video, RS-232 and Gigabit Ethernet signals, supporting uncompressed 4K UHD resolution at 60Hz 4:4:4. This extender pair is particularly recommended for rental and staging applications, 4K live events, and for future-proof operation centers. The extender can transmit HDMI 2.0 signals with 18Gbps over one multimode fiber to a distance of up to 700 meters*. Video and Ethernet signals are transferred over a single optical line.

Using the factory, custom or transparent EDID emulation the user can fix and lock EDID data on the HDMI connector. Advanced EDID Management forces the required resolution from any video source and fixes the output format conforming to the system requirements. The unit offers bi-directional and transparent RS-232 transmission and two separate Gigabit Ethernet signals over the fiber connection.

All devices can be mounted on a rack shelf or used standalone, rack ears also serve easy handling and bump protection, mounting threads on top and one of the sides to conform strict installation safety regulations.

The device features Pixel Accurate Reclocking, a Lightware technology to eliminate jitter and skew generated by low quality sources and multiple daisychained devices. Single fiber technology makes these units fully HDMI compliant without need of a second fiber cable or copper connections.

Galvanic isolation between source and display helps avoiding ground loops and hum effects. No delay occurs in the signal during optical conversion, the video image is transported without frame latency. This feature is crucial in 3D applications and systems where audio is processed separately.

Lightware’s HDMI20-OPTC series supports both HDR10 and Dolby Vision in the HDMI signal at 10 or 12 bit speeds respectively, within its frame bandwidth of 18 Gbps maximum.
