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.
Note
Refer to "Fiber Optic Port Specifications" on page 20 for additional
