Description

Black Box LMC100A-SC-R3 Fast Ethernet Media Converter

Overview

The Black Box LMC100A-SC-R3 is a Fast Ethernet media converter designed to bridge the gap between copper Ethernet cabling and multimode fiber optic networks. This device is critical for extending network distances beyond the 100-meter limit of standard twisted-pair Ethernet, enabling connectivity in larger facilities or across campus environments. It's particularly useful for integrating legacy copper-based surveillance cameras or network devices into a fiber backbone, ensuring reliable 100-Mbps data transmission where it's needed most. The LMC100A-SC-R3 is built for straightforward deployment in commercial and industrial settings.

Compatibility

This media converter is designed to interface with standard 10/100-MBPS Ethernet ports found on a wide range of network devices. It connects to standard RJ-45 copper Ethernet ports on switches, routers, or end devices. On the fiber side, it utilizes an SC connector for 100-MBPS multimode fiber optic cable, compatible with other 100-MBPS multimode fiber transceivers and network equipment. It functions as a transparent bridge, meaning it does not require specific software or firmware compatibility with the connected devices, only that they adhere to Fast Ethernet standards.

Installation Notes

Installation involves connecting a standard Ethernet cable to the RJ-45 port and a compatible multimode fiber optic cable to the SC port. Ensure the fiber cable is rated for 100-MBPS multimode transmission and matches the wavelength specifications of the converter. The device requires no configuration and draws power from its external power adapter (sold separately). For optimal performance, maintain clean fiber optic connectors and avoid sharp bends in the fiber cable that could exceed its minimum bend radius.
