The Brompton Technology Tessera XD 10G data distribution unit delivers a flexible and sophisticated single box solution designed specifically for the challenges of large LED display systems. It works seamlessly with the Tessera SX40 LED processor to provide a single box solution for data distribution.

The XD comes in a rugged chassis, with two mounting options; rack ears for mounting in a 2U 19” rack, or use the holes in the chassis for attaching clamps for truss mounting. A capacitive touch LCD display provides status information for easy fault finding. This includes link quality monitoring of the 10G connections, link/status indicators for each of the 1G outputs, and the name/port of the connected processor.
Unlike typical managed Ethernet switches, the XD does not require lengthy manual configuration to get the best performance. All configuration is handled automatically by the Tessera processor, and firmware reloads can even be performed from within the Tessera software user interface.
XD AND SX40
Together with the SX40 processor, XD provides a powerful toolkit for easily and cost-effectively supporting the biggest LED projects.
Trunk connections between SX40 and XD, or between XD units, use a 10G Ethernet based backbone to reduce the number of home-run connections required. We use a proprietary multiplexing algorithm, built on top of standard 10G Ethernet, to ensure that tight timing constraints are met and all fixtures remain in sync.
To keep cabling as simple as possible, each 10G trunk supports up to ten independent 1G connections to fixtures, each having the same pixel capacity as a 1G Tessera output, subject to the system capacity. Each is fully Gigabit Ethernet compliant, so off-the-shelf switches can also be used to further split the 1G signals. SX40 and XD support both copper and single mode optical fibre trunk connections, and XD can be used to convert between the two media. They use ruggedised Neutrik etherCON and opticalCON DUO connectors, compatible with standard RJ45 and LC-duplex connectors respectively.
Additional XD units can be daisy-chained together to extend the signal, allowing screens in different locations to be connected to a single 10G trunk. All ten 1G outputs on each XD can be used, as long as the combined pixel load on all ports of the same number does not exceed the pixel capacity of a single 1G link.
