ALLNET 102459 network media converter

The ALLNET 102459 is a compact Gigabit Ethernet network media converter that enables signal conversion between copper and multi-mode fiber links at data rates up to 1000 Mbit/s. Designed for installation in small server rooms, wiring closets, and distributed network segments, it supports IEEE networking standards and provides SC fiber optic connectivity for multi-mode fiber runs. The unit operates on a 5 V input and typically consumes around 3 W, offering a small, black enclosure that fits into rack-mounted or standalone deployments where space is limited.

Advantages

This media converter supports full Gigabit Ethernet speeds over multi-mode fiber up to 550 m, ensuring high-throughput links for backbone and aggregation connections. The single RJ-45 copper port negotiates 10/100/1000 Mbps to maintain compatibility with existing Ethernet equipment. The SC fiber connector provides a reliable physical interface for standard multi-mode cabling, while the low power consumption and lightweight design simplify deployment and reduce operating costs.

Suitable for

• Extending Ethernet segments between buildings or floors using multi-mode fiber.
• Connecting switches, routers, or servers to fiber infrastructure in enterprise and SMB networks.
• Replacing or bridging legacy copper links where fiber offers improved distance or noise immunity.

• Product colour: Black
• Weight: 0.23 kg

How to use

Install the ALLNET 102459 by connecting the copper Ethernet cable to the RJ-45 port and the multi-mode fiber cable to the SC fiber connector, ensuring proper connector seating and fiber polarity. Apply the required 5 V power input using a compatible power adapter or power source. Once powered, the device negotiates link speed on the RJ-45 side and establishes the optical link; monitor LEDs or link indicators on connected equipment to confirm successful operation. Place the unit in a ventilated location, avoid direct exposure to moisture, and handle fiber connectors with care to prevent contamination.

Recommendations

For reliable performance, use quality multi-mode fiber cabling and clean SC connectors before connection. Verify that connected network devices support auto-negotiation for proper speed and duplex settings, and keep cable runs within the specified maximum distance of 550 m for multi-mode fiber to maintain Gigabit throughput.
