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.
