4-Port Unmanaged Switch | 2-RJ45 Ethernet Ports, 2-SFP Fiber Ports

Compact Gigabit Switch with Fiber Connectivity

The SG70460 provides two 10/100/1000Mbps copper Ethernet ports and two 1000Base SFP fiber slots in a compact 4-port switching platform.

This combination makes the switch particularly useful when only a small number of Ethernet connections are required but fiber connectivity is also needed.

The SG70460 supports IEEE 802.3u, IEEE 802.3z, and IEEE 802.3ab standards for Fast Ethernet and Gigabit Ethernet connectivity.

Two Gigabit Copper and Two Gigabit Fiber Ports

The SG70460 features two RJ-45 ports supporting 10/100/1000Mbps Ethernet and two SFP slots supporting 1000Base Gigabit fiber modules.

The copper ports support:

• 10Mbps Ethernet
• 100Mbps Fast Ethernet
• 1000Mbps Gigabit Ethernet
• Auto-negotiation
• Auto-MDI/MDI-X
• Full-duplex operation
• Half-duplex operation

The fiber ports accept SFP modules with LC connectors, providing flexibility for different fiber types and transmission distances.

Flexible SFP Fiber Options

The SG70460 supports compatible 1000Mbps SFP modules, allowing the fiber interfaces to be configured according to the network's fiber type and required transmission distance.

VERSITRON's available Gigabit SFP configurations include:

• Multimode fiber up to 220 meters
• Multimode fiber up to 550 meters
• Multimode fiber up to 2 km
• Single-mode fiber up to 10 km
• Single-mode fiber up to 20 km
• Single-mode fiber up to 40 km
• Single-mode fiber up to 70 km
• Single-mode fiber up to 100 km
• Single-fiber bidirectional options up to 10 km
• Single-fiber bidirectional options up to 20 km
• Single-fiber bidirectional options up to 40 km
• Single-fiber bidirectional options up to 60 km
• Single-fiber bidirectional options up to 80 km

The available SFP modules use LC connectors, and the datasheet also identifies CWDM and DWDM modules as available.

This modular approach allows the SG70460 to be configured for different network distances without changing the switch itself.

8Gbps Switching Capacity

The SG70460 provides 8Gbps switching capacity, with a 1K MAC address table and 512Kb frame buffer memory.

This provides efficient traffic forwarding between the switch's copper and fiber interfaces for Gigabit network applications.

Auto-Negotiation and Auto-MDI/MDI-X

The SG70460 supports auto-negotiation and MDI/MDI-X on its Ethernet ports.

Auto-negotiation allows compatible Ethernet devices to establish an appropriate connection speed and duplex mode, while Auto-MDI/MDI-X simplifies cable connections by automatically accommodating different Ethernet wiring configurations.

VLAN and QoS Support

The SG70460 supports VLAN and Quality of Service (QoS) functionality.

VLAN support allows compatible networks to segment traffic, while QoS can help prioritize selected traffic when multiple types of network data share the same Ethernet infrastructure.

Broadcast Storm Protection

The SG70460 includes Broadcast Storm Protection to help maintain network stability when excessive broadcast traffic occurs.

This feature can be useful in network environments where controlling unnecessary broadcast traffic helps maintain consistent network performance.

Jumbo Frame Support

The SG70460 supports jumbo frames, providing additional flexibility for network applications involving larger Ethernet frames.

Jumbo frame support can be beneficial for networks handling larger volumes of data between compatible devices.

Flow Control for Reliable Data Transmission

The SG70460 supports IEEE 802.3x flow control for full-duplex operation and back-pressure flow control for half-duplex operation.

These flow-control functions help regulate traffic between connected devices and reduce the effects of temporary network congestion.

LED Status Indicators

LED indicators provide at-a-glance information about the switch and connected ports. The SG70460 provides power indication, while the copper ports provide link/activity and speed indicators and the fiber ports provide link/activity indicators.

This allows users to quickly check basic connectivity and port status.

Low Power Consumption

The SG70460 has a specified power consumption of approximately 3W, making it an efficient option for small network deployments.

Its low power requirement is particularly useful in installations where minimizing equipment power consumption is important.

Compact Network Design

The SG70460 measures approximately 4.92 × 3.35 × 1.06 inches (125 × 85 × 27 mm), providing a compact footprint for desktop, shelf, equipment-room, and other space-conscious installations.

The switch uses an external power supply with a 100–240VAC, 50–60Hz input and 5VDC, 3A output.

Copper-to-Fiber Network Expansion

The SG70460 is well suited for extending Ethernet networks from copper connections into fiber infrastructure.

A typical installation can use the two RJ-45 ports for nearby Ethernet devices while using the two SFP interfaces to connect to fiber optic network segments. This provides a compact solution for applications where a larger switch is unnecessary.

Typical Applications

The SG70460 is suitable for network installations requiring a small number of Gigabit copper and fiber connections.

Typical applications include:

• Small and medium business networks
• Home and SOHO networks
• IoT applications
• Surveillance systems
• Video conferencing
• Commercial Ethernet networks
• Fiber network extensions
• Copper-to-fiber network connections
• Small network aggregation points
• Data and communications networks
