LevelOne RJ45 to SC Managed Fast Ethernet Media Converter, Multi-Mode Fiber

FVM-1101 is a remote managed Fast Ethernet fiber media converter that converts between 10/100Base-TX and 100Base-FX. It supports both half-duplex and full-duplex modes and is designed for dual-fiber multimode links up to 2 km. The device provides web-based management and IEEE 802.3ah OAM compatibility for remote operation and monitoring when paired with an OAM-capable media converter or switch.

Advantages

The FVM-1101 offers centralized remote management via a built-in web interface and SNMP, allowing administrators to configure and monitor connected converters over fiber. Compliance with IEEE 802.3ah OAM enables interoperability with other OAM-compliant fiber switches, supporting functions such as loopback and dying gasp. Additional features include Link Fault Pass-through (LFP) for transparent fault propagation and IEEE 802.3x flow control to reduce packet loss on congested links.

Key specifications

• Media conversion: 10/100Base-TX to 100Base-FX
• Fiber type: multimode, dual fiber
• Maximum fiber distance: 2 km
• Duplex modes: half-duplex and full-duplex
• Management: web-based interface and SNMP
• OAM: IEEE 802.3ah compliant (supports loopback and dying gasp)
• Link fault handling: Built-in LFP (LLCF/LLR)
• Flow control: IEEE 802.3x
• VLAN support: tag-based VLAN, Q-in-Q

How to use

Install the FVM-1101 by connecting the 10/100Base-TX copper port to a switch or router and the 100Base-FX port to the multimode fiber link. Power the unit and access the web management interface locally or remotely over the network to configure duplex, speed, VLANs, bandwidth control and monitoring options. When used with an OAM-capable remote device, enable IEEE 802.3ah features for remote diagnostics, loopback tests and automatic fault notification.

Recommendations

For reliable operation, use multimode fiber within the specified 2 km range and ensure connected remote equipment supports IEEE 802.3ah if you require OAM features. Keep firmware updated and configure VLANs and flow control according to your network design to minimize packet loss and ensure proper fault signaling.
