Industrial Fast Ethernet to Fiber Media Converter  Slim and Compact Fast Ethernet Media Converter Dual Forwarding modes- Switch and Pure converter Supports Auto MDI/MDI-X, Auto Negotiation Supports Multi-mode 2KM, Single-mode 30KM Auto Link Loss Forwarding(LLF) for fault detection Extreme Low Data Forwarding Latency- 1.6 x 10-6 Sec Wide range DC or AC Power input with DC polarity correction IP-31 grade protection with wide range operating temperature 1.5KV Hi-Pot testing passed

JetCon1301 is a compact 1-port Fast Ethernet media converter designed as the size of a cigarette box, which makes it as ideal model that would physically fit into a chassis with limited space, eg machinery control box and duct assembly room. It also supports switch forwarding mode with abnormal packet filtering and pure converter mode for extreme low latency requirement - Fieldbus and EtherCAT, which needs invariant forwarding latency in 64~1522 bytes packet length. For the easy maintenance and time-saving, JetCon1301 features remote Link Loss Forwarding technology which provides remote link down signal forwarding, acknowledging link events occurred on each end of JetCon1301 to main server. To activate forwarding mode and LLF functions, simply adjust DIP switch then reset the converter, the reconfigurations will be applied.
For the field site harsh environment installation such vibrating machinery or duct assembly room, JetCon1301 can be easily mounted directly onto DIN rail and powering with DC 18~32V, or AC 12~27V where DC input is not available. With the Ingress Protection grade 31 and rigid alloy case, JetCon1301 can survive and have excellent performance under -20~70°C temperature range, severe electromagnetic interference and outcoming vibration.
The highly MTBF- 500,000 hours, 5-year global warranty and endurable performance of JetCon 1301 series give you the reliable choices for hazardous applications.

Reliable Life Vibration & Life Shock Tests
To ensure the reliability networking devices operating in harsh environment successfully, Korenix JetCon 1301 series have passed the following life vibration and life shock tests while units in operating.

• IEC 61000-2-6 life vibration
  5~100Hz/Amplitude 1mm, 0.7G/ 90Min. X.Y.Z. 6 axis
  3~50Hz/Amplitude 3.5mm, 1.0G/ 90Min. X.Y.Z. 6 axis
• IEC 61000-2-27 life shock
  50G, 11ms duration, X,Y, Z, 3 shock/axes ( Total 18 shocks) 

Switching Converter Mode and Pure Converter Mode
The JetCon 1301 can be used in two different modes, switching converter mode and pure converter mode. The store-and-forward technology is implemented in switching converter mode. It will filter out abnormal packets to maintain network efficiency, and support the data forwarding rate up to 148810 bps in full wire speed, packet length from 64 to 1522 bytes. In the pure converter mode, the JetCon1301 only converts signal between copper and fiber port without any packet check and operates in the speed of minimum data forwarding latency.
In tradition, media converter is used for the signal converter between electronic and optical. Most of media converters are not capable to handle all kinds of packet sizes. One major drawback is that can't support 10/100Mbps auto negotiation and auto detection function for the cross-over or straight cable. The pure converter mode has the advantage which it supports extreme low transfer latency. Even the packet-with CRC error, and packet length is below 64 bytes. Some of special devices will need pure converter and they need it do as a dumb without any feature.
JetCon 1301 can be configured as Switch Converter or Pure Converter mode by a DIP Switch. For CSMA/CD compliance, the UTP port supports 100Mbps Full Duplex when set JetCon 1301 as pure converter. If set as 100Mbps half duplex mode, the available link distance will be 60 meters only. In the switch mode, it will not have this limitation. The link distance can be reached to 100 meters.
In pure converter mode, the JetCon1301 will operate with the minimum latency,1.6 micro second. The 2 ports of JetCon1301 is inter-connected via MII signals, therefore the internal switch MAC and packet buffer is not used and the packet length will not be limited and up to 1600bytes. The updated configuration will be available after power reset. 

Link Loss Forwarding Technology
When using traditional fiber converters, users often encounter the following problem: a fiber converter acted like an ordinary unmanaged 2-port switch. When one of a fiber converter's ports failed (e.g. the TX port), the other one (e.g. FX port) would continue to receive data via the media (e.g. fiber), confusing the device on the other end of the media that the connection was still intact. But, by the time the disconnection was found, this error had caused a great amount of loss.
If a port had lost the connection for any reason, JetCon 1301 Industrial Ethernet Converter not only triggers the alarm system by relay output, but also activates the 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 failures.
