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 POE Integration & Multi-Device Adaptation

Combines gigabit high-speed data transmission with IEEE802.3af/at-compliant POE power supply, delivering max 30W per port to power front-end PD devices. Two copper ports support concurrent access of IP cameras, wireless APs and other devices, simplifying deployment.

Long-Distance Transmission & Stable Operation

The fiber port supports multi-mode (up to 2km) and single-mode (up to 120km) transmission, overcoming long-distance connectivity limits. With ESD protection, surge resistance and 500,000-hour MTBF, it maintains reliable performance in complex environments.
