1.25G Gigabit Ethernet Media Converter, SingleMode Dual SC Fiber to Ethernet RJ45 Converter for 10/100/1000Base-Tx to 1000Base-LX, up to 20-km, Pack of 2

It converts media.

I inserted these 2 units into my network, between the Cisco switch and my audio streamer. This broke the electrical connection and replaced it with a fibre optic one. This has the advantage of not transferring electrical noise from my server. I have powered the last optical receiver in this chain, not with the supplied power adapter, but with a spare 5v 1amp DC lead from my linear power supply. Im very pleased with the affect on my hifi system.

I plan on using these for a long run to my Starlink dish and router in an off-grid location. I wanted to avoid Ethernet as the location of the dish exceeds the recommended length for a single Ethernet run (I also dont like the idea of running a long string of copper between my dish and house as we have a lot of lighting storms.) I tested the units inside my office for a couple of weeks in place of my existing Ethernet cable and never even noticed they were there and worked perfectly. The low power requirements also make this perfect for my off-grid scenario.

Good product to establish a fiber connection between two points. For me, lightning surge prevention was the reason to buy it after a nearby lightning strike damaged two switches. One needs the proper cable and always a pair of these. Product is plug&play and works nice at 1GBit.

so far so good!! we ran a fiber line 3000 ft to give internet access on the back side of our farm,and it came right up

Perfect. Worked flawlessly.

Used in conjunction with a 70 meter fiber optic cable to run internet into my detached garage. Low power consumption, no latency albeit theyre transducers per say. Low price, easy to deploy, and extremely dependable.

Excellent price for the speed and ease of use.

I live in an area that frequently sees strong lightning storms, and the cable system often delivers high-voltage surges on the coax that not only fries the modem, it often goes on (across the ethernet cable) to fry connected routers, switches, etc. on the network. Thats a big pain to deal with, never mind expensive. The fix: this kit plus a short (2m) loop of fiber creates an effective air gap that stops those surges from zapping the rest of the gear. Of course, one of the media converters could get fried itself, but thats cheaper than the rest of the gear. It is totally plug and play between my cable modem and the router.
