LevelOne Convertitore media Gigabit gestito RJ45 a SC, fibra multimodale

The LevelOne GVM-1101 Managed Gigabit Media Converter is a compact network device that converts between copper Gigabit Ethernet and multimode fiber connections. It supports data rates up to 1000 Mbit/s, multiple fiber connector types (ST, SC, FC) and a maximum multimode transfer distance of 500 m at an 850 nm wavelength. The unit includes LED indicators for activity, full-duplex, link and power status and accepts 100–240 V input power.

Advantages

The GVM-1101 provides managed operation with web-based and SNMP management, enabling configuration and monitoring. It implements IEEE 802.3x flow control to reduce packet loss and includes Link Fault Pass-through (LFP) functionality (LLCF/LLR) for improved fault transparency. Tag-based VLAN and Q-in-Q support allow flexible network segmentation while maintaining Gigabit Ethernet performance.

Suitable for

• Extending Ethernet networks over multimode fiber up to 500 m
• Integrating fiber links with copper Gigabit Ethernet switches or routers
• Managed network environments requiring SNMP or web-based monitoring
• Deployments needing VLAN tagging or Q-in-Q encapsulation

How to use

Install the GVM-1101 on a stable surface or mount it according to the manufacturer’s instructions. Connect the copper Gigabit Ethernet device to the RJ-45 port and connect the multimode fiber cable to the appropriate fiber connector (ST, SC or FC) matched to your fiber cabling. Power the unit with a compatible 100–240 V supply. Use the web-based interface or SNMP to configure management settings, enable VLAN or Q-in-Q as required, and verify link status via the front-panel LEDs.

Recommendations

For reliable multimode fiber performance, use certified multimode fiber cable rated for 850 nm, keep fiber connectors clean, and ensure proper matching of connector types. Configure IEEE 802.3x flow control and LFP settings according to network requirements to minimize packet loss and to maintain link fault transparency.
