Mini Gigabit Ethernet Network Media Converter (1x 10/100/1000Base-T RJ45 to 1x 1000Base-X SFP)


This fiber to Gigabit Ethernet media converter is configured with a 1x 10/100/1000Base-T RJ45 port and a 1000Base-X SFP port. It is used to contact the RJ45 port switch with the SFP port switch by transferring the copper network to a fiber network and extending the transmission distance of the copper network system at speeds of 1Gbps. Media converters are widely used in structured cabling systems to interconnect fiber optic cabling systems with existing copper cables. 


The fiber optic media converter is compatible with a wide range of 1G SFP transceivers, including 1000BASE-SX/LX, BiDi SFP, CWDM SFP, etc. All of the optical transceivers are available at QSFPTEK.

Convert and Extend Signals


The 1000BASE-X SFP to RJ45 Ethernet Converter extends links over greater distances with fiber optic cable, solving the problem that the transmission distance using the copper cable is limited to 100meters.


Questions & Answers

  • Does this transceiver have any requirements for the brand of the optical module?
    No, It is generic, can be adapted with multi brands of transceivers.
  • Does the 1g sfp to rj45 converter support all VLANS?
    Yes, but you can't configure it.
  • Can this be used with 1g bd sfp? such as T1310/R1490 Bidirectional SFP module.
    Yes, it is. The media converter can support a wide range of transceiver modules, including BIDI SFP, CWDM SFP, DWDM SFP.

    I saw the video on youtube and bought it later, very flexible converter. Use them for 100 and 1000 Mbit sfp:s. Already ordered a few.

    Plug and play, no more configuration required. The LFP function allows me to monitor the LAN, process accidental link issues the first time. btw, they don't list network switches, if there are, I will buy one for a try.
