- Supports twisted pair and optical fiber
- Auto-negotiates speed and duplex
Rugged Deployment
Rail and wall-mountable form factor suits industrial control panels, manufacturing floors, and outdoor enclosures where space is limited and environmental resilience is critical.
Deployment / Use Cases
This converter is engineered for scenarios where fiber optic cabling must interface with copper Ethernet devices, such as connecting fiber backbones to IP cameras, PLCs, or access points in industrial automation, transportation, or utility networks.
Typical applications include extending network segments in factories, connecting remote buildings via fiber with local copper drops, or integrating legacy copper equipment into modern fiber-based infrastructure. Its TAA compliance also makes it suitable for government and educational installations requiring certified hardware.
Industrial Automation
Connect fiber-optic plant backbones to copper-based sensors, controllers, and HMIs on the factory floor, ensuring noise immunity and long-distance signal integrity.
Outdoor/ Harsh Environments
Deploy in weatherproof enclosures or rail-mounted cabinets for traffic systems, oil and gas sites, or renewable energy installations where environmental durability is essential.
