Optical Cables
The maximum cable length is the cable length that the signal can travel without suffering from critical attenuation (degradation).
The maximum distance that any optical link can support is dependent upon attenuation and dispersion at a particular wavelength, maximum bit rate, receiver sensitivity, splice and connector loss, and the data rate used. Refer to SFP specifications for operating parameters.
