Industrial 2-Port Gigabit Redundant Fiber Media Converter with Dual SFP

The UF-IS6212G is an unmanaged industrial 2-port Gigabit redundant fiber media converter with two 10/100/1000BASE-T RJ45 ports and two 100/1000BASE-X SFP ports. It supports 1+1 fiber link redundancy with automatic protection switching and auto-recovery, redundant 12–58VDC power input, and -40°C to +80°C industrial operation. Designed for critical Ethernet networks, it provides a compact and reliable way to maintain network connectivity when the primary fiber link fails.

The UF-IS6212G is a compact unmanaged industrial Gigabit fiber media converter designed for Ethernet networks that require fiber link redundancy and reliable operation in harsh environments.

It provides two 10/100/1000BASE-T RJ45 ports and two 100/1000BASE-X SFP fiber ports. The two SFP ports can be configured as a 1+1 redundant fiber pair, enabling automatic protection switching from the primary fiber link to the backup link when the active connection fails. The system also supports automatic recovery when the primary link becomes available again.

For industrial power environments, the UF-IS6212G supports redundant 12–58VDC power input with reverse-polarity and over-voltage protection. Its fanless IP40 aluminum housing, DIN-Rail mounting, 4KV surge protection and -40°C to +80°C operating temperature make it suitable for industrial Ethernet, transportation, oil & gas, chemical processing, IP surveillance and factory automation networks.

Fiber transmission distance depends on the selected SFP transceiver, allowing the converter to be configured for different fiber types and transmission distances.

How Does 1+1 Fiber Redundancy Work?

The UF-IS6212G uses two SFP fiber ports to create a redundant optical link between network locations.

In a typical point-to-point deployment:

Primary Fiber Link → UF-IS6212G → Remote UF-IS6212G

A second fiber connection provides the backup path:

Backup Fiber Link → UF-IS6212G → Remote UF-IS6212G

When the primary fiber link is active, Ethernet traffic is transmitted through the primary path. If the active fiber connection becomes link-down, the converter automatically switches traffic to the backup fiber port.

When the primary fiber link becomes available again, the redundant system supports automatic recovery.

This 1+1 fiber redundancy architecture is designed for Ethernet networks where maintaining connectivity is important, including industrial automation, transportation, surveillance and other critical network infrastructure.

Note: Fiber transmission distance depends on the selected SFP transceiver. The UF-IS6212G supports 100/1000BASE-X SFP modules, allowing different fiber transmission distances and fiber types to be selected according to the network design.

Daisy-Chain Fiber Network Applications

The dual SFP architecture of the UF-IS6212G can also be used in fiber-based daisy-chain network architectures.

This topology can help connect multiple industrial Ethernet nodes along production lines, transportation infrastructure and distributed field networks while reducing the amount of individual fiber cabling required between network locations.

The UF-IS6212G supports Star, Bus and Tree network topologies, providing flexibility for different industrial Ethernet deployments.

What Problems Does the UF-IS6212G Solve?

A conventional fiber media converter normally relies on a single fiber link. If that link is disconnected or fails, communication between network segments can be interrupted.

The UF-IS6212G adds a backup fiber path to help maintain network connectivity in critical Ethernet applications.

Problem: Single Fiber Link Failure

A damaged fiber cable, disconnected connector or failed optical path can interrupt network communication.

Solution:
The UF-IS6212G supports 1+1 fiber redundancy. The two SFP ports can operate as a primary and backup fiber pair, allowing automatic protection switching when the active link goes down.

Problem: Network Recovery After Fiber Failure

Manual recovery can increase downtime and require maintenance personnel to access the equipment.

Solution:
The redundant fiber mode supports automatic recovery. When the primary fiber path becomes available again, the system can restore the connection automatically.

Problem: Unstable Power in Industrial Environments

Industrial equipment may require more than one power source to improve power availability.

Solution:
The UF-IS6212G supports redundant 12–58VDC power input with reverse-polarity and over-voltage protection.

Problem: Harsh Installation Conditions

Commercial media converters may not be designed for temperature extremes, vibration and electrical interference found in industrial environments.

Solution:
The UF-IS6212G uses a fanless IP40 housing, DIN-Rail installation, 4KV surge protection and a -40°C to +80°C operating temperature range.
