DEV Systemtechnik has thoroughly re-designed its L-band Signal Distribution System DEV 2180, equipping the next appliance generation with a controller and SNMP/Ethernet interface as well as hot-pluggable amplifiers as a standard which can be upgraded without interruption of operations.

The new architecture is space-saving: 16 amplifiers (instead of 12 before) can be housed in one chassis. The existing version of the DEV 2180 may also be obtained as Economy model DEV 2180E at a lower price, which comes without controller and offers a reduced choice of configurations. The new system will be showcased at the IBC2009 in Amsterdam from September 11 to 15 at Stand No. 1.D91. Large cable head-ends and satellite ground stations need to receive and forward signals from multiple satellites. The receivers require either only one of the four L-band signals per satellite or any combination of them. Within 4RU, the Signal Distribution System DEV 2180 accommodates up to three power supplies and 16 amplifiers at the front side. The splitters and/or matrix switches are at the rear side. Each Chassis allows for 16, 32, 48 or 64 outputs —– if desired with mixed impedances (50 or 75 Ohm) for inputs and outputs. Optical inputs are available as an option. The new DEV 2180 with its completely redesigned architecture and new amplifier modules allows for the easy adjustment of variable gain and RF thresholds as well as LNB-bias current via SNMP or Web Interface. The variable tilt functionality for extended L-Band ensures a constant signal level within the entire frequency range – an essential feature for high-availability applications.
