1. Maximum distance for 100 Mbps optical datalinks is dependent on the following factors: type of optical
fiber, duplex mode of both end-nodes, and maximum optical loss budget for each of the optical fiber at
the operating optical wavelength.
2. The cable must be non-dispersion-shifted, dispersion-shifted, or non-zero dispersion-shifted
single-mode fiber optic cable.
