The Motorola SG4000 1GHz Modular 4 x 4 Node provides the network segmentation solutions required by today's expanding broadband communication networks. A true 4 x 4 node, the SG4000 allows operators to independently and incrementally segment the downstream and upstream paths.

As the focus of a fiber deep collector node topology, the SG4000 supports advanced modules, such as optical amplifiers, optical switches and ruggedized optical passives.

The SG4000 node accepts the new DOCSIS®-based status monitor transponder to allow operators to monitor and control node parameters using their existing DOCSIS infrastructure. This node is available as a RoHS-compliant model.
