1.2 Description
The HRR 4104 is a high-performance optical return path receiver that is
optimized to operate in the 5 to 100 MHz return band. This compact (half-slot)
plug-in module is designed for use in the Harmonic HLP 4200 equipment
platform. An HMC 4008 module carrier is needed and mounts two HRR 4104
modules in the platform.
The HRR 4104 is a quad receiver card. The four receivers are designed to
operate independently, or can be configured as four redundant pairs with
another HRR 4104 module.
The HRR 4104 has the following key features:
• Very high packing density
• High RF output level
• Many configuration options
• Automatic or manual gain control to compensate for variations in optical
input
