JetCon 2302 Industrial 2-Channel Fast Ethernet to Fiber Media Converter

JetCon 2302 is not only a compact 4-port switch, but also a 2 channel RJ45 to fiber media converter – an ideal model that would physically fit in harsh environments with intensive severe electromagnetic interference. In switch mode, JetCon 2302 is an Industrial 4-port 10/100Mbps Fast Ethernet Fiber Switch, incorporating 3.2Gbps switching fabric with non-blocking store and forward technology to fulfill the high transmission performance requirements. In converter mode, JetCon 2302 is an Industrial 2-channel 10/100 TX to 100 FX media converter, with an alarm relay to trigger out a real alarm signal for port or power events.

To avoid interferences as well as to extend the network coverage, Single-mode or Multi-mode fiber optic ports meet your needs for up to 30KM long distance transmission.

In addition, to withstand under hazardous environmental conditions, JetCon 2302 provides dual redundant power inputs with wide DC10~60V range, 1.5KV Hi-Pot isolation protection and wide operating temperature for avoiding any power interruption and providing reliable network performance. With its rugged aluminum case, CE/FCC regulatory approvals and 5-year global warranty, JetCon 2302 is your reliable choice for industrial field site applications.

Two-Channel Media Converter and 4-Port Fiber Switch
The JetCon 2302 can be configured by DIP switch in two different operation modes: media converter or fiber switch. In media converter operation mode JetCon 2302 has 2 channels 10/100 TX to 100 FX. For traditional media converter it only has one channel TX to FX. Therefore, JetCon 2302 can be used to substitute two traditional media converters as a result saving cost and power use.

Switch Mode – the device works as a switch equipped with 2 10/100TX RJ-45 ports and 2 100Mbps fiber ports. The packet forwarding uses store and forward technology, which means all the packet flow that goes through the device will be checked and dropped in case if it contains error information. The MAC address table can be updated per 300 micro seconds.

Converter Mode – the device works as a 2-channel media convert with independent traffic path, channel-A and channel-B. The forwarding technology still supports store and forward technology, but the device will not learn and update the MAC address table. All the traffic will be recognized as unknown destination packet flooding with each other and will act as a 2-channel Fast Ethernet media converter.

Excellent system Anti-Electromagnetic Interference

Traditionally, the interference is presented in positive system and disturbs the communication. To prevent the communication from these noise disturbances, some of telecom devices use negative power system to ensure the communication quality. In this regard, JetCon 2302 also can be applied with DC negative power and therefore can provide better anti-jamming ability; not only for the fiber cable anti-interference, but also for the device’s power system.

Wide Range Redundant Power Inputs & True Reliability
In field site applications, unstable power input always impacts on the reliability of system and causes an interruption of communication. To provide a higher reliability, JetCon 2302 has a wide range redundant power input 10~60VDC. In addition, with -25~75°C and -40~75°C (JetCon 2302-w model) wide operating temperature range, the JetCon 2302 can ensure high performance data transmission under harsh environments.
