** Maximum distances attainable on multimode Gigabit Ethernet fiber circuits are primarily dependent upon multimode distor-tion, also known as modal dispersion. Larger aperture fiber optic cable allows more modes to be generated at the launch point; these modes cause the pulse width to spread across a Gigabit Ethernet bit time interval to a point where accurate determination of data (i.e., ones and zeroes) is not possible. These are physical properties that are not specific to this product. These proper-ties also apply to competing products operating in the same frequency spectrum over multimode fiber cable having the same modal bandwidth.
*** Maximum distances attainable on singlemode fiber circuits are dependent upon a circuit's conditions; i.e., the number of splices and patch panels and the number of bends in the circuit path. For comparison with competing products, please use the Link Power Budget for meaningful comparisons.
