Motorola's fiber deep portfolio includes the GX2 optical platform as well as the SG4000 and SG1000 optical nodes. These platforms leverage the latest technologies and allow cable operators to support advanced hybrid-fiber coax architectures such as fiber deep. They also support 1 GHz forward-path passband to accommodate increased bandwidth requirements.
The GX2 is a high-density optical platform with a full complement of application modules for forward-path and return-path, including 1310 nm broadcast transmitters, 1550 nm transmitters, optical amplifiers, high-density analog return receivers, and digital return.
The SG4000 modular node provides an unprecedented level of performance and flexibility. In the fiber deep architecture, the SG4000 is used as the C-node, where optical signals are distributed and collected from the satellite nodes. Specifically for fiber deep applications, Motorola offers an optical switch module for the SG4000 node to enable path redundancy to the C-node, and a series of optical amplifier modules to enable optical signals to travel further into the plant.
The SG4000 also features CWDM or DWDM return path transmitter modules to facilitate node segmentation with the optimum re-use of existing fibers. With the addition of optical passives, forward and return path signals can be wave division multiplexed onto a single fiber. The SG4000 can also be used for the satellite nodes in the fiber deep architecture where its superior capabilities can future-proof the network. As a lower cost option, the SG1000 1X2 node can be used as a satellite node.
