A Bad Cat6 Cable Led This Homeowner to Run Invisible Fiber Through the Walls
Can't fish Ethernet? Use "invisible" fiber instead
A family townhouse in NYC had a Cat6 run that degraded to 100 Mbps, but re-fishing the cable risked damaging thick walls and a wall-mounted Samsung TV. Instead, the author ran 20 meters of invisible fiber — the kind designed for apartment retrofits — between floors, pairing it with a spare MikroTik switch, two media converters, and bidirectional SC SFP+ transceivers. The result: a respectable ~300 Mbps without hiring a contractor.
So yes, even if you don't have fiber to the home, fiber is still useful in a home network.
