GoKawiilHome user bypasses failed Cat6 run with retrofit-style invisible fiber cable
A New York City homeowner found one of their in-wall Cat6 Ethernet runs had degraded to 100 Mbps despite having 2.5 Gbps-capable switches and access points. Rather than fish a new cable through difficult walls or fall back to a weak wireless mesh setup, they installed a thin 'invisible' fiber optic cable—originally designed for apartment and rental retrofits—using a MikroTik switch, media converters, and bidirectional SC SFP+ transceivers to restore high-speed connectivity between floors.
GoKawiil's interpretation of the reporting above, not reported fact.
The case illustrates how fiber cables marketed for landlord- or HOA-restricted retrofits are increasingly being repurposed by general consumers facing tricky in-wall wiring problems, offering a middle path between full cable-fishing projects and unreliable wireless mesh. It also highlights that thick walls and VLAN segmentation needs can rule out typical consumer mesh systems like Eero or Orbi, pushing more technically inclined users toward enterprise-style networking gear repurposed for home use.
- A Cat6 cable degraded to 100 Mbps despite 2.5 Gbps-capable network hardware.
- The user avoided re-fishing cables or using wireless mesh by installing thin, wall-friendly fiber optic cable marketed for apartment retrofits.
- The setup used a MikroTik 10G switch, media converters, and bidirectional SC SFP+ transceivers to connect two floors.
TP-Link MC220L Fiber Media Converter — Since you're running invisible fiber between floors, you'll need media converters on each end to bridge fiber back to Ethernet for your switches and APs. The TP-Link MC220L is a reliable, inexpensive gigabit fiber-to-Ethernet converter that's a popular choice for exactly this kind of home retrofit. It'll let you finally get past that bottlenecked 100 Mbps run without fishing new cable through your walls.
