Arris ARCT02477 AD Cable Access Module 24 Upstream

The Arris ARCT02477 AD is a high-density Advanced Density (AD) Cable Access Module (CAM) designed for the C4 CMTS (Cable Modem Termination System) platform. This specialized hardware component provides 24 upstream ports, significantly expanding the return-path capacity of the headend chassis. It is engineered to meet the increasing demand for upstream bandwidth driven by high-speed data services, video conferencing, and cloud-based applications in DOCSIS 3.0 and EuroDOCSIS environments. The module enables cable operators to implement advanced upstream channel bonding, effectively increasing throughput and reducing latency for end-users across the HFC (Hybrid Fiber-Coaxial) network.The ARCT02477 AD incorporates sophisticated Analog-to-Digital converters and dedicated Digital Signal Processors (DSPs) for each of the 24 channels. This architecture provides superior ingress noise cancellation and advanced frequency agility, allowing the module to maintain stable performance even in challenging RF environments with high levels of interference. The "Advanced Density" design allows for a smaller physical footprint per port, maximizing the slot efficiency of the C4 chassis and reducing the overall cost per upstream channel. The module supports a wide range of modulation profiles, from QPSK to 64-QAM, ensuring optimal data rates based on real-time plant conditions.
Carrier-grade reliability is ensured through a ruggedized mechanical design and high-retention RF connectors that minimize signal leakage and physical wear. The ARCT02477 AD is fully hot-swappable, allowing for capacity scaling or hardware replacement without interrupting services on adjacent modules. It integrates seamlessly with Arris C4 management software for comprehensive monitoring of upstream power levels, signal-to-noise ratios (SNR), and uncorrectable error counts. This module is an essential component for MSOs (Multi-Service Operators) looking to optimize their network for symmetrical bandwidth demands and high-reliability VoIP and data deployments.
