Lightware’s Ubex (Ultra Bandwidth Extender) is a versatile networked AV extender which can operate as a virtual matrix using a standard Ethernet switch as a crosspoint, while also working as a conventional point-to-point extender.

Video signals are handled fully uncompressed and transmitted over 20Gbps optical links. Ubex is designed to be future proof while also delivering on all current needs and expectations of AV professionals.

A primary advantage of this new architecture is scalability. The number of I/O ports in a Ubex-based virtual matrix only depends on the size of the standard Ethernet switch used in the network. The maximum reachable extension distance with multimode modules (OM4) is 400m, 10km with short range singlemode modules, and up to 80km with long range singlemode modules.

The unit is designed to work as transmitter, receiver or transceiver. The change between these modes can be implemented by a firmware change. In transceiver mode the device can transmit and receive 4K signals simultaneously. Ubex supports operating in daisy chain mode, making it especially suitable for large digital signage projects.

Lightware also introduces the HDMI20-OPTC-TX/RX220-Pro, a HDMI 2.0 compatible 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 centres. The extender can transmit HDMI 2.0 signals with 18Gbps over one multimode fibre to a distance of up to 600m.

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 fibre connection.

The device features Pixel Accurate Reclocking, a Lightware technology to eliminate jitter and skew generated by low quality sources and multiple daisy-chained devices. 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.
