Overview & Technical Highlights

Technology System & Brand Assurance

Backed by Levinlink’s professional expertise in optical communication technology, its enterprise media converters deliver high MTBF (Mean Time Between Failures), low power consumption, and reliable long-term performance.

Multi-Device Interconnection

Widely compatible with mainstream Ethernet switches, routers, network cameras, and servers from global brands, supporting seamless data interaction without additional configuration.

Flexible Expansion Support

Optional functional modules (e.g., SFP, LFP) and multi-installation methods enable easy capacity expansion and network upgrade without replacing the core device.

Cross-Scenario Adaptability

Seamlessly integrates with enterprise intranets, surveillance systems, and campus networks, maintaining stable performance across different network environments and bandwidth requirements.

Dual-Port Concurrent Access & Gigabit High-Speed Performance

Two gigabit adaptive copper ports enable simultaneous access of multiple devices, supporting low-latency transmission of HD video and large files. The auto-negotiation function adapts to different network environments without manual parameter adjustment.

Long-Distance Transmission & Energy-Saving Stability

The fiber port covers multi-mode (up to 2km@1310nm) and single-mode (up to 120km@1550nm) transmission, solving long-distance connectivity challenges. With low power consumption (≤3W at full load) and 500,000-hour MTBF, it ensures efficient energy use and reliable long-term operation.
