Μετατροπέας μέσου οπτικών ινών σε Ethernet MikroTik FTC21 — SFP σε RJ45

The MikroTik FTC21 is a fiber-to-Ethernet media converter that links an SFP fiber module to a standard RJ45 Ethernet port. Designed for extending network reach and integrating fiber segments into copper LANs, it enables simple conversion between optical and copper interfaces for office, ISP, and edge industrial deployments. The unit is compact and available in white.

Advantages

The FTC21 provides a straightforward and protocol-transparent conversion between SFP fiber connections and 10/100/1000 Mbps Ethernet over RJ45, allowing integration of fiber links without replacing existing copper equipment. Its compact design and passive functionality make installation and maintenance simple, while compatibility with standard SFP modules ensures flexible use with different fiber types and distances.

Suitable for

• Extending network links between buildings using fiber and connecting to copper Ethernet switches
• Integrating fiber uplinks from ISPs into office or small-business LANs
• Edge deployments where a fiber segment must be converted to RJ45 for existing equipment

Key specifications

• Interface: SFP slot (fiber) to RJ45 Ethernet port
• Ethernet speed: 10/100/1000 Mbps on RJ45
• Form factor: compact media converter
• Color: white

How to use

Insert a compatible SFP fiber module into the FTC21 SFP slot and connect the fiber cable. Connect the RJ45 port to a switch, router, or endpoint using standard Ethernet cable. Power the unit according to MikroTik instructions and verify link LEDs to confirm negotiation or link status. No additional configuration is required on the converter itself when used as a transparent media converter.

Recommendations

Use SFP modules that match the fiber type and distance required (single-mode or multi-mode) and ensure proper handling of fiber connectors. Place the converter in a protected environment away from moisture and excessive heat; verify link speed compatibility with connected equipment to avoid mismatched duplex or speed settings.
