Black Box LGC120A-R4 Gigabit Ethernet Media Converter
Overview
The Black Box LGC120A-R4 is a compact, unmanaged Gigabit Ethernet media converter designed to extend network distances beyond the limitations of copper cabling. It facilitates the connection of a standard Ethernet network to a fiber optic network, enabling data transmission over significantly longer runs. This device is critical for deployments in environments where existing copper infrastructure is insufficient, such as large industrial facilities, campus networks, or long-haul surveillance camera installations. The LGC120A-R4 provides a cost-effective solution for bridging different network media types without requiring complex configuration.
Compatibility
This media converter is designed to interface with standard Gigabit Ethernet (1000BASE-T) copper ports and single-mode fiber optic ports operating at 1310nm. It is compatible with any network device featuring a standard RJ45 Ethernet port and a compatible SFP module slot, enabling seamless integration into existing network infrastructure. It functions as a transparent bridge, supporting all standard Ethernet protocols and frame sizes up to 1536 bytes, making it suitable for a wide range of network equipment, including switches, routers, and IP cameras that utilize SFP transceivers.
Installation Notes
Installation requires a standard RJ45 Ethernet cable for the copper side and a compatible SFP transceiver (sold separately) for the fiber side. Ensure the SFP transceiver's wavelength and fiber type match the connected fiber optic infrastructure. The unit is powered via a standard 5VDC power adapter (included). Operating temperature range is -40°C to 60°C (-40°F to 140°F), making it suitable for demanding environmental conditions found in industrial settings.
