ALLNET ALL-MC102-SC-MM Network Media Converter

The ALLNET ALL-MC102-SC-MM is a multi-mode network media converter designed to bridge copper Fast Ethernet and SC-terminated multimode fiber links. Supporting IEEE 802.3 standards and data rates of 10/100 Mbit/s on the Ethernet side with a single RJ-45 port and a single SC fiber port, the unit enables extension of network segments up to 2000 m over multimode fiber. The compact black housing includes LED indicators for link, power, and speed, and the device operates with a maximum power consumption of 2.5 W, suitable for installations where space and energy efficiency are important.

Advantages

The media converter provides a straightforward way to convert between copper and multimode fiber interfaces without requiring configuration, offering plug-and-play operation. Its support for standard Fast Ethernet speeds (10/100 Mbit/s) and IEEE 802.3 compatibility ensures interoperability with common network equipment. The SC fiber connector and 2000 m maximum transfer distance make it practical for campus, building-to-building, or extended in-building links. Low power consumption and a compact form factor simplify deployment in rack, wall, or desktop locations.

Suitable for

• Extending Ethernet networks over multimode fiber links up to 2000 m
• Connecting switches, routers or network appliances between copper and SC fiber segments
• Small office, campus or enterprise wiring where a single-port converter is required
• Environments requiring compact, low-power media conversion

How to use

Install the ALLNET ALL-MC102-SC-MM on a stable surface or mount it according to site requirements, then connect a Cat5/5e/6 Ethernet cable to the RJ-45 port and an SC-terminated multimode fiber cable to the SC connector. Apply power to the unit and observe the LED indicators: the power LED confirms device power, the link LEDs indicate active connections, and the speed LED shows negotiated Ethernet rate. The device is intended for plug-and-play operation and does not require software configuration; ensure both ends of the fiber link and connected network equipment are set to compatible speeds and duplex modes where applicable.

Recommendations

Place the converter in an environment protected from excessive dust, moisture and heat. Use quality multimode fiber with proper connectors and clean terminations to maintain signal integrity. When integrating into larger networks, verify link speed compatibility and consider using surge protection or proper grounding for fiber-to-copper transition points to improve long-term reliability.
