Home networker replaces faulty Cat6 with "invisible" fiber optic cable
Key points
- Faulty Cat6 cable limited to 100 Mbps.
- Used thin fiber optic cable designed for retrofits.
- Employed media converters and SFP+ transceivers.
- Avoided re-fishing or wireless mesh due to home constraints.
Addressing a Network Bottleneck
A homeowner in NYC encountered a problem with a Cat6 Ethernet cable in their townhouse, which degraded to only 100 Mbps. This performance was insufficient for their network, which included devices capable of 2.5 Gbps speeds. Traditional solutions like re-fishing new cables or using wireless mesh were deemed impractical due to the building's construction and the difficulty of the original cable installation.
The "Invisible" Fiber Solution
The user opted for a less common approach: installing "invisible" fiber optic cable. These thin cables are designed for apartment retrofits and can be adhered to surfaces, avoiding the need for invasive installation. The fiber was used to connect two floors, replacing the problematic Cat6 segment.
Hardware Implementation
The fiber setup involved a MikroTik CRS304-4XG-IN switch, two media converters, and a pair of bidirectional SC SFP+ transceivers. The transceivers use the same SC connector type found in PON networks but operate with Active Ethernet. The media converters bridge the fiber connection to the existing copper-based network infrastructure.
Installation Method
Instead of supergluing the fiber, the user chose to use the included adhesive for the installation. This decision was made to allow for easier removal of the cable if needed in the future. The transceivers support both UPC and other SC fiber types, providing compatibility for the chosen fiber.

Reporting from
A home network user replaced a faulty Cat6 cable that was only achieving 100 Mbps with a thin, "invisible" fiber optic cable. This solution avoided re-fishing new Ethernet or relying on wireless mesh in a challenging home environment. The setup uses media converters and SFP+ transceivers to integrate the fiber into an existing network switch.
