1The numbers given for multimode fiber-optic (MMF) cable refer to the core diameter.
2Cable 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.
3Use with MMF only.
5ITU-T G.652 SMF as specified by the IEEE 802.3z standard.
6Use with SMF only.
7Dispersion-shifted single-mode fiber-optic cable.
8The minimum link distance for ZX GBICs is 6.2 miles (10 km), when an 8-dB attenuator is installed at each end of the link. Without attenuators, the minimum link distance is 24.9 miles (40 km).

1The 1000BASE-ZX GBIC transceiver provides a minimum optical power budget of 23 dB. To determine the supported link distance, you need to measure your cable plant with an optical loss test set to verify that the optical loss of the cable plant (including connectors and splices) is less than or equal to this value. The optical measurement must be performed with a 1550 nanometer light source.
