Optical Implementation Using IEEE-1394.b

power_lol

IEEE Std 1394b-2002 specification allows the use of optical media for longer distances at higher speeds. The use of optical media provides galvanic isolation, lower electromagnetic interference (EMI), and lower interference from the environment. Interfacing 1394.b physical-layer devices (PHYs) may require additional components, depending on the type of fiber-optic transceiver (FOT) selected. This application report addresses the issues associated with using optical transceivers for 1394.b networks with the TI TSB81BA3 PHY device (S800) and TI TSB41BA3 PHY device (S400 and below).
