1. The 1000BASE-ZX GBIC provides a minimum optical power budget of 23dB. To determine the supported
link distance, you should 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 loss
measurement must be performed using a 1550 nm light source.

Ethernet interfaces. Table 2-9

To prevent severe damage to the WS-G6483 Optical Interface Module receiver,
you must install a 5-dB 1550 nm fixed-loss attenuator when fiber-optic cable
lengths are less then 12.4 miles (20 km). To prevent severe damage to the
WS-X6501-10GEX4 receiver, you must install a 5-dB 1550 nm fixed-loss
attenuator when fiber-optic cable lengths are less then 6.2 miles (10 km).
