JetCon 2301 Industrial Fast Ethernet to Fiber Media Converter

JetCon 2301 is a single port Fast Ethernet to Fiber media converter, compliant with EMC requirements of EN 50121-3-2 Railway standard to provide excellent performance under harsh environments featuring intensive vibration/shock and severe electromagnetic interference. Users can benefit from the Single-mode and Multi-mode fiber optic ports of the media converter for providing extended distance transmission of up to 30KM.

The JetCon 2301 supports 4 types of forwarding modes – store and forward, modify cut-through, pure converter and converter modes with auto-changeforwarding modes for various applications, depending on your transmission speed and size preferences. To forward link status changes for alerting remote or central management systems, JetCon 2301 features remote Link Loss Forwarding technology, as a result providing easy maintenance and greatly saving time. Users can easily activate forwarding mode and LLF functions by adjusting the DIP switch and resetting the converter to apply reconfigurations. Moreover, the device provides alarm relay to trigger out a real alarm signal for port or power events.

JetCon 2301 provides power redundancy with wide range DC10V~60V inputs and built-in reverse polarity protection for ensuring the power continuity in the system. Combining 1.5KV Hi-Pot isolation protection and -25~75°C wide operating temperature range, JetCon 2301 withstands vibration and shock in heavy machinery industry and interferes electromagnetic allying power substation environments while keeping your applications running non-stop.

Real-time & Enhanced Data Transmission via 4 Forwarding Modes
JetCon 2301 outstands from other media converters by supporting 4 forwarding switch modes, which makes it a perfect solution for various applications, depending on your transmission speed and size preferences. The 4 operation modes are:

  • Switching mode – to support up to 148810 packets per second and maintain network efficiency by filtering abnormal packets.
  • Modify Cut-through mode – to provide enhanced error checking and avoid possible collisions.
  • Pure Converter mode – to achieve extreme low data forwarding latency by simply converting signal between copper and fiber ports without packet check.
  • Converter mode with Auto-Change-forward function – to enhance transmission by changing packet forwarding speeds.

Auto Fault Detection through Link Loss Forwarding
When using traditional fiber converters, users often encounter the following problem: a fiber converter acting like an ordinary unmanaged 2-port switch. When one of the fiber converter’s ports fails (e.g. the TX port), the other one (e.g. FX port) continues to receive data via the media (e.g. fiber), confusing the device on the other end of the media by indicating that the connection is still intact. But, by the time the disconnection is found, this error causes a great amount of data loss.

If a port loses the connection for any reason, it will act ivate Link Loss Forwarding to shut down the other port; hence, allowing the device on the other end of the media to detect the disconnection. The administrator over the network can be informed of the disconnection immediately, and react promptly to the situation, greatly reducing loss caused by any link failure.
