Product Features
Technical Overview
This media converter operates at Gigabit Ethernet speeds, supporting both 10/100/1000Base-T over twisted pair and 1000Base-X over fiber optic connections. The single RJ45 port handles copper Ethernet connections up to 100 meters, while the SFP slot accommodates industry-standard small form-factor pluggable modules for fiber optic connectivity. The converter automatically negotiates speed and duplex settings, ensuring plug-and-play compatibility with existing network equipment.
Power is supplied via an included AC-DC adapter with a removable power cord, providing reliable operation in varied electrical environments. The device supports both single-mode and multi-mode fiber optics, allowing deployment in short-distance campus networks or long-distance fiber runs depending on the installed SFP module. The compact dimensions of 5.10" × 0.94" × 3.80" (129.54 × 23.88 × 96.52 mm) and lightweight 10.88 oz (308.44 g) design minimize space requirements in crowded network installations.
Key Product Advantages
The LGC5400A media converter delivers reliable media conversion with several distinct advantages for network infrastructure projects. Its dual fiber mode support provides deployment flexibility, allowing the same hardware to work with either single-mode or multi-mode fiber networks simply by changing the SFP module. The rail-mountable design with included DIN rail bracket kit enables secure installation in industrial control panels and network racks without requiring additional shelf space.
Extended Network Reach
Convert copper Ethernet to fiber optic to overcome the 100-meter distance limitation of twisted pair cabling, enabling network expansion across buildings or campuses.
- Supports fiber runs up to kilometers
- Maintains Gigabit performance over distance
- Eliminates electromagnetic interference concerns
Deployment Flexibility
The SFP slot accepts industry-standard modules, allowing customization for specific fiber types, distances, and connector types without replacing the entire converter.
- Compatible with various SFP manufacturers
- Easy field upgrades
- Reduces spare parts inventory
Deployment / Use Cases
This media converter is ideal for extending network segments between buildings where direct copper connections are impractical. It converts existing copper infrastructure to fiber optic, enabling connections across parking lots, between campus buildings, or in industrial facilities where electromagnetic interference affects copper performance. The rail-mountable design makes it particularly suitable for control rooms, manufacturing floors, and telecom closets where space is limited and organized cable management is essential.
Common applications include connecting network switches in separate buildings, linking security cameras over long distances, integrating industrial Ethernet devices in manufacturing environments, and extending network connectivity in educational campuses. The converter also serves as a cost-effective solution for gradually migrating network backbones from copper to fiber, allowing organizations to leverage existing copper infrastructure while building out fiber capabilities.
Building-to-Building Connectivity
Connect network equipment between separate structures using fiber optic cabling for immunity to lightning strikes and ground potential differences.
Industrial Network Integration
Deploy in manufacturing environments to connect PLCs, HMIs, and other industrial Ethernet devices while withstanding electrical noise and vibration.
Physical Profile
The converter features a slim, industrial design optimized for rail mounting in control panels and network cabinets. The compact footprint occupies minimal space while providing full media conversion functionality. The durable construction withstands typical industrial environments, and the included DIN rail mounting bracket ensures secure installation without additional hardware. The terminal block power connection provides reliable power delivery with screw-down terminals that resist vibration-induced disconnection.

User Manual
FAQ
What types of fiber optic connections does this media converter support?
The Black Box LGC5400A supports both single-mode and multi-mode fiber optic connections through its SFP slot. The specific fiber type, connector style, and transmission distance depend on the SFP module installed. Single-mode modules typically support longer distances (up to tens of kilometers), while multi-mode modules are optimized for shorter campus or building runs (up to 550 meters). You can select the appropriate SFP module based on your existing fiber infrastructure and distance requirements.
How is this media converter powered?
This converter is powered by an included AC-DC power adapter with a removable power cord. The adapter connects to the converter via a terminal block interface, which provides secure screw-down connections that resist vibration and accidental disconnection. The power input accepts standard North American 120V AC power, converting it to the DC voltage required for converter operation. The removable power cord allows for easy replacement if damaged and facilitates installation in various international markets with different plug types.
