Question Need Advice - 140m Ethernet Run Between Buildings

[Reda_ELF]

Hey community,

I'm facing a technical challenge and could really use your expertise. I need to establish a wired network connection between two points 140 meters apart - well beyond the standard 100m limit for Ethernet.

Key Details:

• Outdoor installation (connecting two separate buildings)
• Requires stable, reliable bandwidth
• Must be wired (WiFi isn't suitable for this application)

Looking for real-world experience:

1. Has anyone successfully implemented a similar long-distance run?
2. What solutions actually worked in practice?
3. Any pitfalls or lessons learned I should know about?

I'm especially interested in hearing about what's worked (or failed) for others in field deployments.

Thanks in advance for sharing your knowledge!

This is really pretty simple. Use multi mode fiber with a converter at each end.
