Arris Group Inc. said Insight Communications Co. Inc. will be the first cable operator to deploy its new 2.5 Gigahertz digital return transmitter, a technology designed to lower costs by minimizing the number of active elements on a cable network.

Insight initially will deploy the technology in Louisville, Ky.; and Evansville and Bloomington, Ind.

Arris' digital return transmitter uses dense wave division multiplexing, and enables up to 20 wavelengths to be multiplexed onto a single fiber in an optically-passive hub.
