Media converter MikroTik Sedir 1x SFP 1x RJ45 1000Mb/s, max 1000 Mb/s, metal housing, 100–240V AC

The MikroTik Sedir media converter provides protocol-neutral conversion between fiber and copper Ethernet links, featuring one SFP slot and one RJ45 Gigabit port. Designed for 10/100/1000Base-T to 1000Base-FX conversion, it supports up to 1000 Mb/s throughput and can extend fiber links depending on the installed SFP module. The unit comes in a black metal housing with front-panel LEDs for link, activity and power status, and accepts 100–240 V AC power input.

Advantages

The compact metal housing ensures durability and shielding in rack or desktop installations while built-in LEDs allow quick visual diagnostics of link and activity. With an SFP modular connector the converter supports a range of fiber transceivers to match distance and fiber type requirements. Universal AC power input makes the device compatible with standard power sources in office and industrial environments.

Suitable for

• Integrating single-mode or multi-mode fiber segments into Ethernet networks
• Extending backbone or access links where copper runs are impractical
• Connecting fiber runs from ISP or transit links to switch or router RJ45 ports
• Environments requiring a small, durable media conversion appliance

Key specifications

• Interfaces: 1 × SFP slot, 1 × RJ45 Gigabit (10/100/1000Base-T)
• Maximum throughput: up to 1000 Mb/s
• Fiber reach: dependent on installed SFP module (manufacturer example reach up to 10,000 m or more when using appropriate transceivers)
• Indicators: LEDs for link, activity and power
• Housing: metal, black
• Power input: 100–240 V AC, 50–60 Hz, 0.3 A

How to use

Install an SFP transceiver compatible with the required fiber type and distance into the SFP slot, then connect the fiber optic cable to the transceiver and the RJ45 copper cable to the Gigabit port. Apply AC power within the specified range and verify LED indications for power and link status. No additional configuration is required for basic media conversion; the device transparently converts electrical Ethernet frames to the optical domain and vice versa.

Recommendations

Choose SFP modules that match your fiber type (single-mode or multi-mode), wavelength and distance requirements. For reliable operation, use quality patch cords and ensure correct transceiver and cable compatibility. Place the converter in a ventilated area and verify power requirements before installation.
