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

6-Port Gigabit Ethernet Switch with Fiber Connectivity

The SG70660 provides a combination of four Gigabit copper Ethernet ports and two 1000Base SFP fiber slots in a compact network switch.

This configuration allows network equipment connected through standard RJ-45 Ethernet to communicate with fiber-connected network segments, providing a practical solution for extending Ethernet connectivity over fiber.

The switch supports IEEE 802.3u, IEEE 802.3z, and IEEE 802.3ab standards.

Gigabit Copper and Fiber Connectivity

The four RJ-45 ports support 10/100/1000Mbps Ethernet, allowing the SG70660 to connect to network devices operating at Fast Ethernet or Gigabit Ethernet speeds. The two fiber interfaces accept 1000Base SFP modules with LC connectors.

The copper ports support:

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

This makes the SG70660 suitable for networks containing a mixture of legacy 10/100 Ethernet devices and Gigabit Ethernet equipment.

Flexible SFP Fiber Options

The two SFP slots provide flexibility when extending the network over fiber. The SG70660 supports compatible 1000Mbps SFP modules with LC connectors and can be used with multimode, single-mode, and single-fiber configurations.

Available VERSITRON Gigabit SFP options 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

CWDM and DWDM modules are also available.

The appropriate SFP module should be selected according to the required fiber type, transmission distance, wavelength, and network configuration.

12Gbps Switching Capacity

The SG70660 provides 12Gbps switching capacity with a 1Mb frame buffer and a 1K MAC address table.

This switching capacity provides efficient traffic forwarding between the four copper Ethernet ports and two fiber interfaces.

Auto-Negotiation and Auto-MDI/MDI-X

The SG70660's copper ports support auto-negotiation and MDI/MDI-X, simplifying network installation and connection to compatible Ethernet equipment.

Auto-negotiation allows connected devices to establish an appropriate Ethernet speed and duplex configuration, while Auto-MDI/MDI-X eliminates the need to manually determine whether a straight-through or crossover cable is required.

VLAN and QoS Support

The SG70660 supports VLAN and Quality of Service (QoS) functionality.

VLAN support can be used to segment network traffic, while QoS provides a method for prioritizing traffic when different types of network data share the same infrastructure.

These capabilities make the SG70660 useful for networks where traffic organization and prioritization are important.

Jumbo Frame Support

The SG70660 supports jumbo frames, providing additional flexibility for networks that use larger Ethernet frames.

Jumbo frame capability can be particularly useful in network environments where high-volume data transfers are common.

Flow Control for Reliable Data Transmission

The SG70660 supports IEEE 802.3x flow control for full-duplex operation and back-pressure flow control for half-duplex operation.

Flow control helps regulate traffic between connected devices and can reduce packet loss caused by temporary congestion.

LED Status Indicators

LED indicators provide visual information about switch and port activity. The SG70660 provides a power indicator along with link/activity and speed indicators for the copper ports and link/activity indicators for the fiber ports.

These indicators allow users to quickly check connectivity and link status without requiring additional diagnostic equipment.

Compact Desktop Network Design

The SG70660 measures approximately 5.51 × 3.94 × 1.18 inches (140 × 100 × 30 mm), providing a compact footprint for desktop, shelf, equipment-room, and other space-conscious installations.

The switch uses an external power supply rated for 100–240VAC input and 5VDC, 2A output.

Low Power Consumption

The SG70660 has a specified power consumption of approximately 4W, making it a relatively low-power option for small network deployments.
