Gigabit Ethernet Network Media Converter (10/100/1000Base-T RJ45 to 1000Base-X 1310nm 2km)

The Gigabit Ethernet media converter enhances communication distance and efficiently transmits data through fiber optic cables. It is designed to meet the increasing demand for higher power requirements in network equipment like network cameras, VOIP telephones, wireless LAN access points, and other devices. By leveraging the RJ45 interface, this media converter enables the direct delivery of data and power to network devices without additional power outlets or electrical cabling. The QSFPTEK media converters offer compatibility with a wide range of transceiver modules, including general 1000Base SFP transceivers, BIDI transceivers, CWDM transceivers, and more. It is essential to ensure consistency in the wavelength, speed rate, and distance of the transceiver modules used at both ends of the media converter.

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

  • 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.
  • 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.
