The IEEE 1394 High Performance Serial Bus is a versatile., high-speed, and low cost method of transferring digital data between personal computer peripherals and consumer electronics devices. IEEE 1394 can transport data at 100/200/400 Mbps. They called it ¡§Fire Wire¡¨ |

Application |
| |
¡´Digital interface ¡V no need to convert digital data into analog and then digital again for processing, which will have a loss of data integrity.
¡¹ Easy to use ¡V no terminators, devices ID etc¡K.
¡¹ Hot plugged for plug and play applications.
¡¹ Cheap ¡V the high volume consumer market will achieve low-cost implementation.
¡¹ Daisy chain connection.
¡¹ Fast ¡V Consumer electronic devices ( up to 100Mbps data rate), as Video/Game devices, Connect, conventional PC peripheral, Digital audio type (DAT) recorders. Connect electronic components(up to 200Mbps data rate), as High end keyboard synthesizer, Digital camcorders and VCRs. Professional and industrial market can up to 400 Mbps data rate. |

Cable construction. |
| |
The fully shielded connector will have six contacts. The connector plug termination can be made by crimp, insulation displacement, insulation piercing and soldering.
The cable consist of two twisted pairs (signal pair) & two power conductors. The signal pair carry to b alan ced differential data signal, while the power conductors carry the bus power (about 8-40V DC).
The signal pair will have individual braid (60-65%) shield. And overall cable had a outer shield (90-95% braid copper wire over spiral wrap metallized polyester tape, with the metal to the outside).
