10-Port Unmanaged Industrial Switch | 8-10/100 Ethernet, 2-100FX MM ST

Flexible Copper and Fiber Connectivity for Industrial Networks

The SF708532 is designed for industrial Ethernet networks that require reliable 10/100Mbps connectivity with integrated fiber optic transmission.

The switch provides eight 10/100Mbps RJ-45 ports and two 100Mbps fiber ports, while Ports 7 and 8 provide dual connectivity that allows either copper or fiber to be used. This gives network designers additional flexibility when integrating fiber into an existing copper Ethernet network.

100Base-FX Multimode Fiber with ST Connectors

The SF708532 is equipped with two 100Base-FX multimode fiber ports using ST connectors. The model supports multimode fiber with a transmission distance of up to 2 km at 1310nm.

This ST fiber configuration is particularly useful for industrial installations using existing ST-terminated multimode fiber.

• Fiber speed: 100Mbps
• Fiber standard: 100Base-FX
• Connector: ST
• Wavelength: 1310nm
• Maximum distance: 2 km
• Fiber ports: 2

The SF708532-specific fiber specifications are identified in the model table on page 2 of the VERSITRON datasheet.

Dual Copper or Fiber Connectivity

One of the key features of the SF708532 is the dual-connectivity design of Ports 7 and 8.

These ports can provide either copper or fiber connectivity, allowing the switch to adapt to different network configurations without requiring a separate media converter.

This can be especially useful when an industrial network needs to transition between copper Ethernet and fiber optic infrastructure.

Reliable 10/100 Ethernet Switching

The SF708532 uses wire-speed store-and-forward switching for Ethernet traffic. The switch supports IEEE 802.3x flow control for full-duplex operation and back-pressure flow control for half-duplex operation.

The eight copper interfaces support auto-negotiation and Auto-MDI/MDI-X, simplifying connection to compatible Ethernet devices and eliminating the need to manually configure transmission and receiving pairs.

Far End Fault Detection

The fiber ports include a Far End Fault function, providing an additional tool for identifying problems with the fiber connection.

This feature can help network operators identify fiber link issues and troubleshoot connectivity between network locations.

Broadcast Storm Protection

The SF708532 incorporates Broadcast Storm Protection to help maintain network stability when excessive broadcast traffic occurs.

This is useful in industrial networks where maintaining stable Ethernet communications is important for connected equipment and control systems.

Power Failure Alarm

The SF708532 includes a relay output for power failure alarm notification. The relay interface uses two terminal contacts and is rated for up to 30VDC/1A or 120VAC/0.5A.

This provides an additional method for integrating the switch into industrial monitoring or alarm systems.

Industrial Construction for Harsh Environments

The SF708532 is designed for industrial environments with an operating temperature range of -30°C to +70°C and a storage temperature range of -30°C to +85°C. Relative humidity is specified at 5% to 95%, non-condensing.

The product is also designed to provide industrial-rated emission and immunity performance, supporting reliable operation in electrically demanding environments.

DIN-Rail and Panel Mounting

The SF708532 supports both DIN-rail and panel mounting, providing flexibility when installing the switch inside control cabinets, equipment enclosures, or directly within industrial systems.

The optional mounting hardware identified in the datasheet includes the DRB-1 DIN Rail Mounting Kit and PMB-1 Panel Mounting Kit.

Compact Industrial Design

The switch measures approximately 5.51 × 4.17 × 1.57 inches and consumes a maximum of approximately 7.3W.

Its compact form factor makes it practical for installations where industrial network equipment needs to fit within limited cabinet or enclosure space.

Compatible Fiber Configurations

The SF7085x family includes several fiber configurations, allowing VERSITRON to provide models with different fiber types, connectors, and transmission distances.

For the SF708532, the specified configuration is:
