A Pair of 1.25G/s Bidi Gigabit Multi-Mode Fiber Ethernet Media Converter with 2PCS Bidi SFP LC Dual Transceiver Module Included, 10/100/1000Base-Tx to 1000Base-SX SMF RJ45 to SFP Slot up to 550M

These were great from converting from cat5 to fiber to get from one side of the house to the other, I have a higher end router with an sfp for the wan port, and I wanted to use the fiber, my switches have 10gig sfp ports and I am using those as well

I’m using these to get my internet out to my workshops. Dead easy to install and work as advertised. Will be buying a few more for the other shop.

Needed to extend the fiber Ethernet connection from the router where in comes in from the service provider. WIFI 100 feet away in the home speed was much slower, like 75% slower.. With this pair of media converters and a single LC-LC fiber cable - 30 meters long does the job. Working bi-directional of a single fiber I get the same data rate as seen at the router, about 950 MBPS up and download with no data speed loss. Awesome technology. The transceivers transmit and receive on different wavelengths so it's full duplex.

It works exactly as stated

Connectivity and speed are accurate and works properly. These don't seem to be SUPER durable but are typical for what you would get at this price. I have used these in multiple environments and have had no issues what so ever.
