●PRODUCT OVERVIEW
■The DRB450N Quad Digital Return Receiver utilizes ARRIS's state-of-the-art digital reverse technology to receive 5-50 MHz, 5-65 MHz, or 5-100 MHz RF signals. 5-100 MHz modes can also be used to carry common mid-band splits such as 5-85 MHz RF return. Its' capabilities allow deployment of compact and robust high-speed digital broadband systems.
■ARRIS's DR3450N receiver interfaces with the BPB400C-AS Optical Receiver Back Plate, enabling up to 16 digital receivers (four DRB450N modules per BPB400C back plate) to be installed in four adjacent module slots of ARRIS's BRU CHBOOO chassis. A total of 48 receivers (12 DR3450N modules) and three associated BPB400C back plates can be installed in a single CHBOOO chassis while supported by redundant power supplies.
■In single channel mode, each DRB450N receiver module can terminate digital return transmission from four node clusters. The data extracted from each optical link is converted through a high-speed digital-to-analog converter (DAC), resulting in a single RF output signal. Up to four optical links are received per module in this mode providing four RF outputs. The DR3450N also supports concatenation for daisy chaining of node signals in single channel modes.
■In dual channel "2-fer" mode, each DRB450N module terminates up to two return path wavelengths. The advanced design provides simultaneous conversion of digital return path traffic from two RF return segments coming from the node on the same optical wavelength. Two wavelengths providing a total of four RF outputs are supported by each DR3450N module operating in mode.
■Used in combination with NC2000/NC4000 and VHub based DT4250N Digital Transceivers with CWDM or DWDM SFPs in optical nodes, the "2-fer" mode of the DR3450N allows quick and cost effective doubling of the amount of return bandwidth available from any node in the network, therefore conserving and optimizing the cable operators' investment in the fiber network.
■The DR3450N also supports digital RF Return protocols of ARRIS OM6000, OM4100, OM4120, and OM2741 Nodes using the DT7x30N Digital Transmitter, HLN Nodes using the DT6250N, and CH3000 Chassis/Hubs using the DT3550N Digital Transceivers, providing network integration and inter-operation with mixed ARRIS node and hub platforms.
