1. The maximum drive distance (up to 70 km) depends on the quality of the installed single-mode 
fiber-optic cable segment. Use the Link Power Budget to calculate the maximum cable length of the 
attached segment. The Link Power Budget must not exceed those specified in this table. The 
MGBIC-08 input power must not exceed -3 dBm. Otherwise, saturation could occur.
