BLACK BOX 10/100/1000TX/1000 SFP Media Converter

The BLACK BOX LGC135A-R3 is a high-performance Ethernet media converter that seamlessly bridges 10/100/1000Base-TX copper networks with 1000Base-SX/LX fiber optic networks via an SFP slot. Designed for reliable and cost-effective network extension, this converter supports auto-negotiation, auto MDI/MDI-X, and jumbo frames up to 9K bytes. Its metal housing ensures durability in demanding environments, while Link Fault Pass-Through (LFP) aids in rapid fault isolation. Ideal for connecting distant network segments or integrating fiber into existing copper infrastructures.

Advantages

Extend network reach up to 80 km (with appropriate SFP module) while maintaining full Gigabit throughput. The plug-and-play design requires no configuration, and the DIP-switch configurable LFP feature simplifies troubleshooting. Low power consumption (max 3.5W) and compact metal chassis make it suitable for desktop or rack-mount installations.

Suitable for

• Connecting remote offices or campus networks over fiber
• Upgrading legacy copper networks to fiber backbone
• Industrial or commercial environments requiring reliable media conversion
