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.

Gigabit High-Speed Transmission & Adaptive Compatibility

The gigabit-class ports enable high-speed data transmission with low latency, meeting the bandwidth needs of HD video and large-file transfer. The copper port’s 10/100/1000Mbps auto-negotiation adapts to different network speed requirements without manual configuration.

Long-Distance Coverage & Energy-Saving Stability

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