Black Box LMC270A-MM-ST Industrial Ethernet Media Converter
Overview
The Black Box LMC270A-MM-ST is a ruggedized industrial media converter designed to extend Fast Ethernet (100-Mbps) network connectivity over multimode fiber optic cable. This device bridges the gap between standard copper Ethernet ports and fiber optic infrastructure, enabling reliable data transmission in environments where standard network equipment would fail. Its robust construction makes it suitable for deployment in factory floors, transportation hubs, or any location with significant vibration, temperature extremes, or electrical interference. The LMC270A-MM-ST model specifically supports ST connectors for multimode fiber, providing a cost-effective solution for shorter-range fiber links up to 2 kilometers.
Compatibility
This media converter is designed to interface with any standard 10/100Base-TX Ethernet device, including industrial switches, IP cameras, and automation controllers. It supports the IEEE 802.3u Fast Ethernet standard. The multimode fiber port is compatible with standard 100Base-FX transceivers using ST connectors.
Installation Notes
The unit requires a 12-48 VDC power input, which must be supplied separately. It is designed for DIN-rail mounting, common in industrial control cabinets. Ensure proper ventilation around the device to maintain optimal operating temperature.
