(Multimode Only)

1.The maximum drive distance (up to 2 km) depends on the quality of the installed multimode 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-LC03 input power must not exceed -3 dBm. Otherwise, saturation could occur.
