2:1 bdr Dual Receiver Module 
On the receive end, typically in a large hub or headend, the bdr Dual Receiver 
Module receives the optical signal, performs conversion back to the baseband data 
stream, demultiplexes the data stream and converts the two resultant data streams 
back to analog reverse path signals for routing to termination equipment. 
The bdr Dual Receiver Module contains two independent receivers, each with its 
own optical input and pair of RF outputs, integrated into one module. This 
equipment is housed in the Prisma II Chassis, the industry’s first carrier-class 
platform – providing critical network reliability, equipment density, and high 
performance functionality. For instructions on installing the receiver, refer to the 
Prisma II™ Integrated bdr 2:1 Dual Receiver Module Installation and Operation Guide
part number 4021745. 
The following block diagram shows the receiver module's internal components.
