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.
