Examples
Figure 12 is an example of a copper connection loss. The OSD2151 will detect that there is no copper
connection received and then disable the transmission to the fiber port. The 1000Base-X switch will
thus be notified that there has been a copper link loss.
FIGURE 12: COPPER CONNECTION LOSS
Figure 13 is an example of a fiber connection loss. If the OSD2151 does not receive a valid optical
signal from the switch, transmission to copper port will be disabled.
