At Cable-Tec Expo, Aurora Networks is unveiling the fifth generation of its Universal Digital Return transmitter, repackaged for the company's recently acquired PWRBlazer node platforms. Aurora's digital return technology implementation in the DT6250N is intended to enable operators to upgrade the performance of their PWRBlazer nodes while reducing power consumption.While the PWRBlazer line, including the HLN3144 and HLN3142 nodes, already supports digital return, Aurora's new backward-compatible DT6250N transmitter platform is more cost and power efficient. The new transmitters use 8.5 watts for their CWDM and DWDM versions, more than halving the power consumption for each.
