Simplify plant upgrades with modular RF design • Improve amplifier reach with optional GaN technology and increased station tilt • Maintain current amplifier spacing with high output GaAs technology • Expand return path bandwidth with plug‐in diplex filter support to 85 MHz • Minimize RF drift over temperature with optional analog or QAM ALC
Drop‐in RF modules are a cost‐effective way for operators to upgrade networks with existing legacy C‐COR 2‐port housings—such as the FlexNet 700 series, Flex Max® FM340 series, and Flex Max® FM330 series line extenders—with minimal network disruption. The FM331‐LE 1 GHz Line Extender Amplifier is designed to extend existing systems or build out new networks, providing operators with the ability to quickly add high output capacity with minimal disruption. By integrating the FM331‐LE into their design systems, operators can more cost‐effectively upgrade 750/870 MHz system bandwidths.
The FM331‐LE maintains operating specifications, such as gain and tilt, at 750 MHz and 870 MHz, with extended gain and tilt out to 1 GHz. These unique design considerations eliminate the additional cost of resplicing by enabling operators to reuse legacy line extender housings and existing spacing, making the FM331‐LE line extender drop‐in RF module an ideal choice for 1 GHz system upgrades. The FM331‐LE also provides excellent forward and return path performance. The unit features 1 GHz GaAs technology that improves distortion performance and minimizes system performance issues relative to Composite Second Order (CSO) and Composite Triple Beat (CTB). Optional GaN technology provides higher output capacity for extended reach or fiber deep applications. FM331‐LE line extenders are available with three level control options: automatic level control (ALC), thermal level control (TLC), and no level control (NLC). The ALC models offer a variety of common analog and QAM/digital pilot frequencies. In addition, ARRIS offers an ALC pilot frequency option with a gain hold feature, which enables the amplifier to adjust output levels to the mid‐range automatically if its pilot frequency level drops by 10 dB or more. The gain hold option also allows operators to choose between 609 MHz and 711 MHz pilot frequencies. ARRIS also offers several frequency split options for the FM331‐LE, including the 85/105 MHz frequency split for expanding broadband networks. The unit’s plug‐in filter design allows for bench upgradability to any offered frequency split for maximum flexibility.
