Black Box LGC125A-R4 Gigabit Ethernet Media Converter
Overview
The Black Box LGC125A-R4 is a 10/100/1000-Mbps Ethernet media converter designed to bridge copper Ethernet networks with fiber optic infrastructure. This unit is essential for extending network distances beyond the limitations of standard Ethernet cabling, making it suitable for connecting surveillance cameras or other network devices located far from the main network switch. Its ability to convert between copper and fiber ensures compatibility and allows for robust, long-distance data transmission in industrial or campus environments.
Compatibility
This media converter is compatible with any network device featuring a standard 10/100/1000-Mbps RJ-45 Ethernet port and any fiber optic network infrastructure utilizing 1000-Mbps SFP modules. It is designed to integrate seamlessly with existing network equipment, including switches, routers, and IP cameras that require a fiber uplink or connection over extended distances. Specific compatibility is not limited to any particular brand of network equipment, provided the interface standards (RJ-45 and SFP) are met.
Installation Notes
Installation requires connecting a standard Ethernet cable (Cat5e or higher) to the RJ-45 port and inserting a compatible 1000-Mbps SFP module into the SFP slot. Power is supplied via an external power adapter (sold separately). Ensure the operating environment is within the specified temperature range for reliable performance.
