LevelOne RJ45 to SC Managed Fast Ethernet Media Converter, Single-Mode Fiber, 20km

The LevelOne Web Smart Media Converter FVS-3120 converts between 10/100BASE-TX and 100BASE-LX single-mode fiber (SMF) with SC connectors. It provides web-based management that allows an administrator to access the converter remotely to monitor status, configure settings and perform firmware updates, improving overall network reliability and supporting higher-bandwidth applications.

Advantages

The converter supports HTTP management with remote firmware upgrade, simplifying maintenance. Built-in DHCP client, ICMP and ARP support enable straightforward network integration. IEEE 802.1Q VLAN and Q-in-Q (double VLAN) support allow flexible traffic segmentation, while 802.3x flow control and LLR (Link Loss Return) improve data integrity and link resilience.

Key specifications

• Media conversion: 10/100BASE-TX to 100BASE-LX SMF (SC)
• Management: Web-based HTTP management
• Remote update: Firmware upgrade via web interface
• Protocols supported: ICMP, ARP
• IP setup: DHCP Client
• Link features: LLR (Link Loss Return)
• VLAN: IEEE 802.1Q and Double VLAN (Q-in-Q)
• Flow control: IEEE 802.3x flow control

How to use

Install the converter between the copper Ethernet device (10/100BASE-TX) and the single-mode fiber link (100BASE-LX SC). Assign or obtain an IP address using the DHCP client, then access the web management interface through a browser using the device IP. Use the web interface to configure VLANs, enable flow control and perform firmware upgrades as needed. Monitor link status and logs via the management pages to verify operation.

Recommendations

For reliable operation, use single-mode SC fiber compatible with 100BASE-LX specifications and ensure proper fiber connectors and cleanliness. Keep firmware up to date via the web management interface and enable flow control if connecting to devices that support 802.3x to reduce packet loss.
