Product Features
Technical Overview
This media converter operates with Gigabit Ethernet technology and supports multiple network standards including 1000Base-T, 100Base-TX, 100Base-FX, and 1000Base-X. The two RJ-45 ports provide copper connectivity, while the two SFP+ expansion slots allow for fiber optic module insertion, offering flexibility in media selection based on distance and environmental requirements.
The device efficiently converts signals between twisted pair and optical fiber media, extending network reach beyond typical copper limitations. With a power draw of just 7 watts from the included adapter, it delivers reliable performance without excessive energy usage.
Relevant factors for this section include Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
Key Product Advantages
This converter provides essential advantages for network professionals needing reliable media conversion in space-constrained installations.
Dual Media Support
Simultaneously handles twisted pair and optical fiber connections, allowing mixed-media network designs without separate conversion devices.
- Supports both copper and fiber optic cables
- Enables hybrid network topologies
Compact Industrial Design
The DIN rail mountable form factor saves space in industrial control panels and network cabinets while providing secure mounting.
- Fits standard DIN rails
- Minimal footprint for crowded installations
Flexible Expansion
Two SFP+ slots accept industry-standard optical modules, providing customization options for different fiber types and distances.
- Accepts various SFP+ transceivers
- Future-proofs fiber connectivity
Deployment / Use Cases
The LGC340A-R2 media converter is ideal for extending network segments between buildings, connecting fiber backbone networks to copper-based edge devices, or integrating legacy equipment with modern fiber infrastructure.
Common applications include industrial automation systems where control networks need to span long distances, surveillance camera installations requiring extended cable runs, and data center environments where fiber connectivity must interface with copper-based servers or switches.
Industrial Network Extension
Connect PLCs, sensors, and control devices across manufacturing floors using fiber for noise immunity and distance.
Building-to-Building Links
Extend network connectivity between structures using fiber for lightning protection and longer reach than copper alone.
Physical Profile
Measuring 3.50" high, 0.90" wide, and 3.90" deep, this compact converter fits easily into tight spaces while providing full conversion functionality. The DIN rail mounting capability ensures secure installation in industrial panels, and the approximately 1-pound weight makes it easy to handle during deployment.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 3.50" (88.90 mm), 0.90" (22.86 mm), 3.90" (99.06 mm), 1 lb (453.59 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
