Review on 🔌 1.25G/s Bidi Gigabit Single-Mode Fiber Ethernet Media Converter (2PCS Bidi SFP LC Transceiver Module Included) - 10/100/1000Base-Tx to 1000Base-SX SMF RJ45 to SFP Slot, Up to 30KM by Badpuppy Warton

I used to have a very long CAT5e cable for my internet (my ISP's RJ45 connector is in the worst place so it has to run a long way to my router). Sometimes I had disconnections because the cable was too long. I bought a set of two of these modules (no modules), added two used SFP modules I got cheap, and ran speed tests that confirmed they could run at full gigabit with no problems. do not heat up at all, so consume almost no energy, which is a plus. The only thing I want to see might be throughput, but not a display limiter for my use case.
