The Arris S33 architecture is centered around the Broadcom BCM3390 chipset, which provides the computational overhead required for 2.5 Gbps throughput. Structural dimensions are minimized for a compact footprint, necessitating a vertical orientation to manage the high thermal density of the processor. The I/O panel features a single 2.5 Gbps port and a secondary 1 Gbps port, though concurrent utilization is restricted to environments with multiple ISP-assigned IP addresses.
Performance metrics confirm support for DOCSIS 3.1 OFDM/OFDMA subcarrier processing, ensuring low-latency delivery for synchronous applications. The chassis material is engineered for passive heat dissipation, though performance can be compromised if placed in environments lacking active airflow. Diagnostic status is provided via a single multi-color LED, requiring access to the internal WebUI for detailed signal analysis.
- Data Interface: 1x 2.5G Base-T, 1x 10/100/1000 Base-T.
- Silicon: Broadcom BCM3390 with LLD support.
- Configuration: 32x8 SC-QAM and 2x2 OFDM.
If your setup requires a more traditional multi-port Link Aggregation design, the Motorola MB8600 provides four ports for bonded connections. This unit represents the current performance peak for the DOCSIS 3.1 modems hardware class.
