Yes, it is optic fiber internet.
Hi there, I have a query. We just purchased a new apartment in China and made extensive renovations. The walls were replaced, the wiring updated, and I wanted a LAN port in every room with CAT6 cables since they’re priced similarly to CAT5. Now we have a 500mbps internet connection. As the cable enters the wall and heads outside, I’m trying to figure out what it is. The engineer connected the incoming line to our new modem, and eventually only a blue optical connector remained. My concern is whether using a regular RJ45 cable for the blue connector means it’s converting to fiber optics, or if I’m just seeing something. The speed test came back at 439mbps.
The blue connector isn't compatible with RJ45 ports. It's designed specifically for fiber cables only. A fiber modem transmits light signals, not electrical ones, so mixing it with a copper cable doesn't work. The way data travels is entirely different. Unless you're linking the wide area network to a standard LAN connection, it's surprising. I might be mistaken—can you share an image of the cable?
I'm also based in China telecom (Beijing) and can verify that it's genuine fiber optic.
Fiber connection needs to be changed to copper at the end user's location. It is usually transformed into Ethernet or coaxial cable, which is mainly used for broadcasting services.
