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 Thomas Landis

I bought these as a pair of 1.25Gbps singlemode to singlemode fiber optic ethernet converters with a Bought a pair of dual-band SFPs. So far, the best I can get is a transfer rate of 93 Mbit/s. Maybe I have the wrong fiber optic cable? (Jeirdus 2 Meters 6 Feet LC-LC Fiber Optic Cable Jumper Optical Patch Cord Simplex Singlemode 9/125 LC-LC). I also noticed that one SFP-LC transceiver module has the module number SFP-GE-LX-SM1310 and the other module has the model number SFP-GE-LX-SM1550. One module is Tx13/Rx15 and the other module is Tx15/Rx13 so they seem to be compatible. Update: Tried multimode cable (Multimode Simplex Fiber (50/125) - LC-LC) with pretty much the same results, 95Mbps. Still none and almost 1000 Mbps. Last update: I connected a converter to my main router via the RG45 ethernet ports. The router status LED for this connection showed only a 100 BASE-T Ethernet connection.
