Network Media Converter EFB Elektronik EL025V2

The EFB Elektronik EL025V2 is a compact network media converter that links copper Ethernet and single-mode fiber networks at Fast Ethernet speeds. Designed for installations that require a reliable fiber extension of an existing 10/100 Mbit/s Ethernet link, this unit supports a maximum data rate of 100 Mbit/s and uses an SC fiber connector at a 1310 nm wavelength to achieve long-range connections up to 10,000 meters. Its metal housing provides mechanical protection and stable operation in rack, cabinet or wall-mounted setups.

Advantages

The device offers a straightforward way to extend network segments over long distances while preserving Fast Ethernet performance. Its single fiber port and RJ-45 Ethernet port simplify integration with standard network equipment. The metal enclosure enhances durability and heat dissipation, reducing the risk of physical damage in demanding environments. Support for single-mode fiber and SC connectors ensures compatibility with common telecom and campus backbone cabling.

Suitable for

• Extending local area networks between buildings or across a campus
• Connecting remote network devices such as switches, routers or CCTV systems
• Integrating fiber links into existing Fast Ethernet infrastructures
• Environments where a robust metal housing is required

Key specifications

• Maximum data transfer rate: 100 Mbit/s (Fast Ethernet)
• Ethernet LAN port: 1 × RJ-45
• Fiber ports: 1 × SC (single-mode)
• Supported fiber wavelength: 1310 nm
• Maximum transfer distance over fiber: up to 10,000 m
• Casing: metal housing for increased durability

How to use

Install the EL025V2 on a stable surface or in a cabinet and connect the copper network device to the RJ-45 port using a standard Ethernet cable. Terminate the single-mode fiber cable with an SC connector and plug it into the fiber port. Ensure correct fiber polarity and use appropriate fiber patch cords or pigtails if necessary. Power the unit according to the supplied power adapter specifications and verify link/activity LEDs to confirm connectivity. Configure connected network devices to operate at Fast Ethernet speeds or allow auto-negotiation if supported.

Recommendations

Place the converter in a ventilated area away from excessive dust and moisture. For long fiber runs, use certified single-mode fiber and test the link with appropriate optical tools to verify signal loss and continuity. Match link speed settings on connected devices to 100 Mbit/s if fixed-speed operation is required. Regularly inspect fiber connectors for contamination and clean them with suitable fiber cleaning tools to maintain optimal performance.
