Media Converter with One SFP Slot

Ethernet to Fiber Media Converter provides the capability to connect UTP copper-based Ethernet devices to a fiber optic link, allowing for the utilization of the advantages offered by optical fiber. These advantages include:

  • Extending the reach of Ethernet signals: When using unshielded twisted pair (UTP) cable, copper-based Ethernet connections are limited to a maximum data transmission distance of 100 meters. However, by employing an Ethernet-to-fiber conversion solution, it becomes possible to extend this link over distances exceeding 120 kilometers using fiber optic cabling.
  • Safeguarding data transmission from noise and interference: In environments where there is a high level of electromagnetic interference (EMI), such as industrial plants, Ethernet to Fiber Media Converters can be utilized. EMI can lead to data corruption when transmitted over copper-based Ethernet links. However, data transmitted over fiber optic cables are completely immune to this type of noise. By employing an Ethernet to Fiber Media Converter, you can interconnect your copper-Ethernet devices over fiber, ensuring the integrity of your optical data transmission.
  • Allowing for future bandwidth expansion: Fiber optic cables possess significant bandwidth capacity. While the notion of limitless bandwidth is not entirely accurate, typical optical fibers can support bandwidth ranging from approximately 100 MHz/km (using multi-mode fiber) to over 1000 MHz/km (using single-mode fibers). This provides ample room for expanding bandwidth requirements in the future.


Benefits of Ethernet to Fiber Media Converters

  • Ethernet to fiber and fiber back to Ethernet links
  • Create copper-fiber connections with fiber switches
  • Fast Ethernet or Gigabit Ethernet to multi-mode or single mode
  • Provide you with the flexibility to add fiber on a port-by-port basis
  • Protect your investment in existing copper Ethernet-based hardware
  • Enjoy the benefits of fiber without having to make wholesale changes

Furthermore, the 10/100/1000Base-Tx to 1000Base-Fx media converters feature a single SFP slot, making them highly adaptable for gigabit network deployments. They enable the extension of a copper-based gigabit connection over fiber optic cable, allowing for maximum distances of up to 80km.

Additionally, these converters can be easily installed into a standard converter chassis, and the procedures for installation and operation are straightforward. The front panel of the converter is equipped with a set of Diagnostic LEDs, which allows for local monitoring of the operation status.

Moreover, by simply changing the inserted SFP module, the media converter offers effective solutions for networks with different transmission rates (100M and 1000M), modes (single mode and multi-mode), distances (2km, 10km, 20km, 40km, 60km, and 80km), and interfaces (LC/SC, etc).
