Custom IEEE 1394 Cable

The IEEE-1394 interface, also known as Firewire, is a serial interface standard developed by the IEEE standards organization that supports up to 63 nodes, and both synchronous and asynchronous transfer modes.

IEEE-1394 is a commonly used connector for connecting high-speed external hard disks, CD-ROMs, DVD-ROMs, scanners, printers, digital cameras, camcorders, and other devices that require support for high transfer rates (up to 800 Mbps).

Romtronics has an experienced design and manufacturing team, who can create any combination of IEEE-1394 cables that meet high flexibility and environmental specifications. We provide custom FireWire (1394) cable assemblies for numerous industrial applications. Feel free to request a quote and free samples from our factory.

IEEE1394 cable interface form

There are three types of IEEE-1394 interfaces: 9-pin, 6-pin, and 4-pin. 6-pin interfaces are available for hexagonal shapes, and 4-pin interfaces are available for small quad shapes.

The first IEEE1394 interface developed by Apple was the 6-pin interface. Later, Sony saw the advantage of the fast data transfer rate of the 6-pin interface and worked to improve it by creating a new design, which is commonly known as the 4-pin interface, called iLink.

In 2008, IEEE 1394 began promoting 9-pin interfaces and cables to meet the challenges posed by the USB 3.0 specification. As a result, IEEE-1394 is often used in printers, scanners, digital cameras, and other devices.

Transmission Speed

  • IEEE1394 4PIN Transmission Speed 400Mbps.
  • IEEE1394 6PIN Transmission speed is 400Mbps.
  • IEEE1394 9PIN Transmission speed is 800Mbps.
  • IEEE 1394a applies to the 400Mbps standard, while IEEE 1394b applies to the 800Mbps standard. Therefore, the transmission speed of IEEE 1394b is faster than IEEE 1394a, allowing for faster data transfer.
  • Another difference is that IEEE 1394b is backward compatible with IEEE1394a devices. If you need to connect a device that is suitable for IEEE 1394a (400Mbps), you will need to use a cable with 9 pins on one end and 6 or 4 pins on the other (depending on the type of terminals used by the device) to make the connection. Note, however, that the transfer speed will be limited to 400Mbps when connected using this cable.

Advantages

  • IEEE1394 also supports peripheral hot-plugging and plug-and-play.
  • Support synchronized data transmission.
  • 1394A can support the longest theoretical line length of 4.5 meters.
  • IEEE1394 can be used as an external bus but also can be used as an internal bus.

Disadvantages

  • Fewer applications, now support for IEEE1394 equipment is not too much.
  • IEEE1394 bus needs to take up a lot of resources, so you need a high-speed CPU.
