    2.5G Ethernet Network Mini Media Converter (1x 10/100/1000M/2.5GBase-T RJ45 to 1x 1000M/2.5GBase-X SFP)

     

    This 2.5G fiber to copper Ethernet mini media converter is configured with a 1x 10/100/1000M/2.5GBase-T RJ45 port and a 1000M/2.5GBase-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 2.5Gbps. Media converters are widely used in structured cabling systems to interconnect fiber optic cabling systems with existing copper cables.

    Product details

    Flexible signal extension and conversion

     

    By utilizing media converters and fiber optic cables, the link can be extended to longer distances, allowing for the migration of the network to fiber while leveraging the existing copper cable infrastructure.

     

     

    Easy and Efficient Operation

     

    Hot-swappable design, plug-and-play. Easy to install and troubleshoot, no additional configuration is required for connectivity.

     

     

    LFP Rapid Alarm Link Failure

     

    LFP (Link Fault Pass-through) functionality enables quick detection of failed links within a short timeframe, minimizing potential losses caused by link failures.

     

     

    Questions & Answers

    • All (5)
    • Can this transceiver be used with Cat6 cables?
      Certainly, as long as it has an RJ45 connector.
    • Can this media converter accurately transmit LACP packets?
      The media converter functions as a Copper-to-Fiber converter, extending transmission distances. LACP packets primarily handle link aggregation traffic within the device. In principle, transmission should proceed without any issues.
    • 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.
