LevelOne μετατροπέας μέσου RJ45 σε SFP Managed Gigabit

The LevelOne GVM-1000 is a managed Gigabit media converter that converts 10/100/1000Base-T Ethernet to 1000Base-X fiber via an SFP slot. Designed for local and remote management, the device supports IEEE 802.3ah OAM, allowing monitoring and configuration of remotely connected converters when paired with an OAM-capable switch or media converter. It supports half- and full-duplex operation, VLAN tagging (including Q-in-Q), and provides LED indicators for activity, FDX, link and power.

Advantages

The GVM-1000 provides Web-based and SNMP management, enabling configuration and monitoring of speed, duplex, VLANs and bandwidth control both locally and remotely. It includes IEEE 802.3x flow control to reduce packet loss and built-in Link Fault Pass-through (LFP) including LLCF/LLR for improved link fault visibility. Its SFP fiber connector and Gigabit Ethernet RJ-45 port allow flexible fiber and copper connectivity in compact black housing.

Suitable for

• Extending Ethernet networks over single-mode or multi-mode fiber using SFP modules
• Remote link monitoring and management in OAM-enabled fiber deployments
• Connecting legacy copper devices to fiber backbones at Gigabit speeds

How to use

Install an appropriate SFP module for the desired fiber type, insert it into the SFP slot and connect the fiber cable to the module. Connect copper devices to the RJ-45 port. Power the unit from an appropriate 100–240 V supply. Use the Web UI or an SNMP management system to configure link speed, duplex mode, VLAN tagging (including Q-in-Q), bandwidth limits and OAM settings. When deployed with an OAM-capable remote converter or switch, use the Web interface to monitor remote link status and perform loopback tests.

Recommendations

For reliable operation, use manufacturer-recommended SFP modules that match the fiber type and distance requirements, enable OAM when managing remote links, and configure IEEE 802.3x flow control and LFP to detect and propagate link faults promptly.
