Black Box LMC400A Fast Ethernet Media Converter
Overview
The Black Box LMC400A is a compact Fast Ethernet media converter designed to bridge the gap between copper twisted-pair Ethernet cabling and fiber optic networks. This device is essential for extending network reach beyond the typical 100-meter limit of copper, enabling surveillance systems to connect cameras or NVRs across longer distances or in environments where fiber is the preferred infrastructure. Its 100 Mbps throughput ensures sufficient bandwidth for standard definition or even some higher-resolution IP cameras without becoming a bottleneck. The black, compact form factor allows for discreet installation in network closets or near edge devices.
Compatibility
This media converter is designed to interface with standard 10/100Base-TX Ethernet ports found on most IP cameras, network switches, and NVRs. It requires a compatible 100Base-FX fiber optic transceiver (sold separately) to establish a fiber link. It is compatible with any network device that adheres to the 10/100Base-TX Ethernet standard, making it a versatile component for mixed-media network designs.
Installation Notes
Installation involves connecting a standard RJ45 Ethernet cable from your copper network device (e.g., switch, camera) to the LMC400A's Ethernet port. A fiber optic transceiver module must be installed in the converter's SFP slot to connect to the fiber optic network. Power is supplied via a standard 5V DC power adapter (sold separately). Ensure the operating environment is within the specified temperature range for reliable operation.
