3 Overview
3.1 FRAS overview
3.1.1 Product description
The Analog Forward Path Receiver - Standard (FRAS) is designed to plug into the latest generation Advanced Intelligent
Multi-services Access platform - the AIMA3000.
The FRAS is available in single and dual port configurations. It incorporates a low noise front-end circuit that receives
optical wavelengths from 1260 nm to 1620 nm and converts them into RF signals for Master Antenna Television (MATV),
CATV, and broadband applications. The supported RF bandwidth is from 45 to 1218 MHz.
The module oers a superior frequency response with a low distortion profile and low noise characteristics.
The FRAS optical receiver module features automatic gain control (AGC), which is based on broadband detection or
through optional pilot signal detection.
The RF output AGC threshold level and the slope can be managed remotely.
3.1.2 Product Key Features
■Plug-and-play AIMA3000 platform module
■Superior performance with a low noise profile and minimal distortion characteristics
■High RF output for flexible deployment
■Supports Automatic Gain Control (AGC) for a stable RF output
■Electronic slope control
■Electronic gain setting and AGC adjustable thresholds
■Broadband GaAs amplifier technology
■Support for CENELEC and NTSC standards up to 110 channels (analog and digital)
■Comprehensive status monitoring and alarm with the NMS network management software
■HMS compliant
■Remote firmware upgrade and auto upload/download of configuration files through ASMM web interface or using
the NMSE
■Bulk firmware updates through the NMSE
■FCC, CE and RCM(1) compliant
(1) See Declaration of Conformity for current status.
