Modern high-speed Ethernet relies on optical transceivers to carry data over fiber for long distances, especially in data centers, enterprise networks, and carrier infrastructure where copper cannot meet speed or reach requirements.

Here are two different types of optical transceivers 😎👇

So, I put an #Ethernet cable under a floor mat, and the friction tore the outer casing apart!

Surprisingly, the inner casings on the conductors inside are still intact, but the destruction of the outer casing has untwisted them. They're just straight wires now.

Also surprisingly, despite the cable now being majorly out of spec, it still carries 100Mbps without incident. Now that's some quality electrical engineering.

Anyway, I got a rubber floor conduit to protect the untwisted pairs.
