Ensure that the dust covers are installed when the fiber is not in use. Dirty or scratched connectors can lead to high losses
on a fiber link.
3.3.10 IRIG-B
There is a round IRIG-B connector at the back of the CPU module, marked "IN". Use is optional.
IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The
IRIG-B code allows time accuracies of up to 100 ns. The GE MultiSync 100 1588 GPS Clock as well as third-party equipment
are available for generating the IRIG-B signal. This equipment can use a global positioning system (GPS) satellite system to
obtain the time reference so that devices at different geographic locations can be synchronized. The IRIG time code
formats are serial, pulse width-modulated codes that can be either DC level shifted or amplitude modulated (AM). Using
IRIG-B input, the D30 operates an internal oscillator with 1 µs resolution and accuracy.
Figure 3-33: Options for IRIG-B connection
Using an amplitude-modulated receiver causes errors up to 1 ms in event time stamping.
