LAN/WAN network building: test and know how to locate your cabling
Posted by jpluimers on 2025/09/04
I have seen too many sites where cabling was laid en never tested before actual use, which meant locating the cabling and faults was a nightmare.
Be sure to have good (which can be very simple, but more complex when Power over Ethernet is involved) testing hardware and use it during installation. You will thank yourself later.
A few videos that can be helpful:

That last two video were in fact my starting point, but since I run both copper and fiber, I opted for [Wayback/Archive] NOYAFA PoE Multi-Function Network Cable Tester for CAT5 CAT6 Tracker, Optical Power Meter, Cable Length Measurement, Port Flash, with Type C Lithium Battery : Amazon.de: DIY & Tools.

¹ Note that the NOYAFA devices have FC connecotrs do not come with LC female to FC male adapters, so I got this pair: [Wayback/Archive] Guakiili 2pcs LC Female to FC Male Hybrid Converter Adapter Fiber Optic Power Meter Coupler Optical Single Mode Connector : Amazon.de: Electronics & Photo
