JetCon Series Industrial Media Converter

JetCon Series offers fast Ethernet to fiber converters and serial to fiber converters, enabling you to expand your network through fiber optic communications and/or serial fiber ring extending your network distance. JetCon can be configured in 2 different ways-Switching Converter Mode or Pure Converter Mode.

Switching Converter Mode or Pure Converter Mode

The JetCon1301 can be used in two different modes- the switching converter mode and the 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 packet 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 ports without any packet checking and operates in the speed of minimum latency of packet transfer.

When Configured as Switching Converter mode:

When Configured as Pure Converter mode:

Traditionally a media converter is used for the electronic to optical signal conversion. Most media converters are not capable of handling all kinds of packet sizes. One major drawback is that some converters 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 that it supports extreme low transfer latency. Even packets with CRC errors and packet length is below 64 bytes. Some of the special devices will need the pure converter and some need it as a dumb unit without any feature.

JetCon 1301 can be configured as Switching Converter or Pure Converter mode by a DIP Switch. For CSMA/CD compliance, the UTP port supports 100Mbps Full Duplex while setting JetCon 1301 as the pure converter. Setting 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 reach 100 meters. In the pure converter mode, the JetCon1301 will operate with the minimum latency, 1.6 microseconds. The 2 ports of JetCon1301 are inter-connected via MII signals. Therefore, the internal switch MAC and packet buffer are not used, and the packet length up is to 1600bytes. The updated configuration will be available after power reset.

JetCon 1302 also a 3-port Switch

Providing two 10/100BaseTX ports and one 100Base-FX uplink, JetCon 1302 can be used as either a 3-port
switch or RJ-45 to fiber optic converter for two devices. For easy diagnosis in the field, the JetCon 1302 provides one relay output to trigger alarm automatically if any port has errors. To upgrade legacy equipments from 10Base-TX (10 Megabit) Ethernet devices to 100 Megabit Ethernet, the JetCon 1302 converter automatically detects speed and provides both 100Base-TX and 100Base-FX uplinks. Any industrial Ethernet device can also connect the JetCon 1302 to a high reliability fiber optic network in fulfilling the following applications, such as fiber enabling any Ethernet devices, linking 2 Ethernet devices to one fiber port, adding fiber link to any Ethernet network and using the second 100BaseTX port for network diagnostics.

Serial Fiber Ring to Expand Connected Devices and Distance

The JetCon 2401 series supports two transmission configurations, Peer to Peer in full duplex and Serial Fiber Ring (SFR) in half duplex. In a Peer-to-Peer configuration, two fibers are required between the
two converters, one for data in each direction (RX and TX). To expand the number of connected serial devices, you can connect the fiber transmitter to the rest of the slaves and eventually back to the master
