Převodník síťových médií EFB Elektronik EL027V2

The EFB Elektronik EL027V2 is a network media converter designed to bridge copper Ethernet and multimode fiber connections at Gigabit speeds. It provides a 1000Base-T RJ-45 input and a 1000Base-SX SC fiber output supporting multimode fiber types 50/125 µm and 62.5/125 µm with a maximum link distance of up to 550 meters. Housed in a metal enclosure and compliant with FCC and CE standards, the unit includes an external power supply and diagnostic LEDs for link and activity monitoring.

Advantages

The EL027V2 supports autonegotiation and Auto MDI/MDI-X on the copper interface to simplify installation and eliminate the need for crossover cables. Its Gigabit-capable ports ensure up to 1000 Mbit/s throughput while maintaining backward compatibility with 10/100 Mbit/s devices. The SC fiber connector and multimode compatibility make it suitable for common short-range fiber links, and the metal housing provides mechanical durability for rack or desktop placement.

Suitable for

• Extending a Gigabit Ethernet network over multimode fiber up to 550 m
• Connecting switches, routers or network devices between copper and fiber segments
• Small office and enterprise backbone links where multimode fiber is used

How to use

Place the EL027V2 on a stable surface or mount it in a rack if appropriate. Connect the copper network cable to the RJ-45 port and the multimode SC fiber cable to the SC port, ensuring correct fiber type and connector alignment. Attach the included external power supply and verify the diagnostic LEDs for power, link and activity status. The device will autonegotiate the link speed and polarity on the copper side; no special configuration is required for basic operation.

Recommendations

For reliable performance, use multimode fiber that matches the supported core size (50/125 µm or 62.5/125 µm) and observe proper fiber handling practices. Keep cable runs within the specified 550 m maximum for 1000Base-SX links and avoid excessive bending or stress on fiber connectors.
