Chapter 2 Preparing for Installation

Determining Cable Distances

10-Gigabit Ethernet

Table 2-8 lists the fiber-optic transmission specifications for the 10-Gigabit

Ethernet interfaces. Table 2-9 lists the optical power specifications for the

10-Gigabit Ethernet interfaces.

Caution 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).

1000BASE-ZX 0/5 -3 -23

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.
