blog About Ruijie Unveils RGSF2920 Series for Highspeed Fibertothehome Networks

In today's digital era, network infrastructure performance and reliability have become critical indicators for measuring regional and enterprise competitiveness. Traditional network equipment faces significant challenges in meeting future high-speed, high-density access requirements. Ruijie Networks' RG-SF2920 series of all-optical PoE switches offers an innovative solution with its forward-looking design, exceptional performance, and deep understanding of future networking needs.

Technical Innovation: Setting New Standards for Optical Access

The RG-SF2920 series represents more than just hardware advancement—it embodies a fundamental rethinking of network architecture through several key breakthroughs:

Integrated Optical Ethernet and FTTR Architecture

The series combines all-optical Ethernet architecture with Fiber-to-the-Room (FTTR) deployment, extending fiber connectivity directly to endpoints. This eliminates the limitations of traditional copper cables in speed, distance, and interference resistance, providing unprecedented bandwidth for applications like 4K/8K video, VR/AR, and cloud gaming.

Multi-Rate Ethernet Port Evolution

The switches feature flexible port configurations including standard 1GE RJ45 ports alongside innovative 2.5GE/5GE RJ45 ports—critical for supporting Wi-Fi 6/6E access points at full capacity. Two 10GE SFP+ uplink ports provide robust aggregation capabilities for growing traffic demands.

Enhanced PoE/PoE+ Power Delivery

Certain models support PoE/PoE+ across multiple ports, with the RG-SF2920-8GT2MG2XS-P model delivering up to 30W per port and 150W total power output. This integrated power and data transmission simplifies cabling while improving reliability.

Independent Optical Module Design

Unlike traditional POL solutions with onboard optical modules, the RG-SF2920 series uses discrete modules that eliminate soldering-related reliability issues. This point-to-point transmission design ensures stable data forwarding with low error rates.

Robust Environmental Protection

The switches feature 8kV surge protection on service ports and 6kV protection on power ports. With an operating temperature range of -40°C to +70°C and resistance to humidity/altitude variations, they're suitable for telecom cabinets, wall mounting, or concealed installations.

Application Scenarios: Versatile Deployment Options

The compact, flexible RG-SF2920 series serves diverse networking environments:

Smart Offices and Enterprise Networks

Ideal for modern workplaces requiring high bandwidth and PoE-powered devices (IP phones, APs, cameras), the fanless design (<20dB noise) suits noise-sensitive environments.

Hospitality and Multi-Dwelling Units

The FTTR model provides dedicated fiber connections to individual rooms. The sleek form factor allows discreet installation in telecom boxes or wall cavities.

Education and Healthcare

High-reliability design and security features support mission-critical operations in schools, research facilities, and medical institutions.

Smart Campuses and Data Center Edge

High-speed ports (2.5GE/5GE/10GE) make these switches effective access/aggregation layer devices for bandwidth-intensive environments.

Performance Advantages: Foundation for Reliable Networks

High Switching Capacity

The RG-SF2920-8GT2MG2XS-P delivers 76 Gbps switching capacity and 56.5 Mpps forwarding rate, ensuring smooth traffic handling.

Advanced Thermal Design

A "shark fin" heatsink and die-cast metal enclosure increase heat dissipation by 37%, enabling fanless operation while maintaining sub-20dB noise levels.

Enhanced Durability

Metal construction (housing and RJ45 ports) plus independent optical modules contribute to a 300,000-hour MTBF rating.

Space-Efficient Installation

Compact dimensions (210×235×55mm) with multiple mounting options accommodate space-constrained deployments.

Management Simplicity: Unified Intelligent Operations

Integrated with Ruijie's Unified Network Controller (RG-UNC), the series enables:

Visualized Automation

Real-time monitoring, granular alerts, and centralized configuration through a single interface streamline deployment and maintenance.

Zero-Touch Replacement

Automated fault diagnosis and device swapping minimize service disruption during hardware failures.

Comprehensive Feature Set

Support for VLAN, STP/RSTP/MSTP, ERPS, LLDP, DHCP, static routing, IGMP Snooping, ACL, QoS, and 802.1X authentication enables complex network policies.

Conclusion

The RG-SF2920 all-optical PoE switch series represents a significant leap forward in network infrastructure. By combining cutting-edge optical technology, flexible connectivity options, robust performance, and intelligent management, it provides a future-proof foundation for digital transformation across industries.
