1.The numbers given for multimode fiber-optic (MMF) cable refer to the core diameter.

2.Cable distances are based on fiber loss. Additional factors, such as the number of splices and the optical quality of the fiber, can affect cabling distances.

3.ITU-T G.652 SMF as specified by the IEEE 802.3z standard.

Note The minimum cable distance for all 100-MB SFP transceivers listed, both MMF and SMF (G.652), is 6.5 feet (2 meters).

Table B-2lists the fiber loss budgets for the 100-MB SFP transceivers.
