Table 1. Cisco GBIC Port Cabling Specifications

GBIC	Wavelength (nm)	Fiber Type	Core Size (Micron)	Modal Bandwidth (MHz/km)***	Cable Distance
Cisco 1000BASE-SX	850	MMF	62.5 62.5 50.0 50.0 50.0	160 200 400 500 2000	722 ft (220 m) 902 ft (275 m) 1640 ft (500 m) 1804 ft (550 m) 3281 ft (1000 m)

		SMF	9/10	N/A	6.2 miles (10 km)
Cisco 1000BASE-ZX	1550	SMF	9/10	N/A	43.4 to 62 miles (70 to 100 km)**

* Mode-conditioning patch cord is required over legacy MMF and should not be used over OM3.** Cisco 1000BASE-ZX GBIC can reach up to 62 miles (100 km) by using dispersion shifted SMF or low-attenuation SMF; the distance depends on fiber quality, number of splices, and connectors.*** Specified at transmission wavelength.

Table 2 shows fiber loss budgets for 1000BASE-SX, 1000BASE-LX, and 1000BASE-ZX.

Table 2. Fiber Loss Budgets for 1000BASE-SX, 1000BASE-LX, and 1000BASE-ZX

Device	Type	Transmit (dBm)		Receive (dBm)
		Max	Min	Max	Min
WS-G5484	1000BASE-SX	-3	-9.5	0	-17
WS-G5486	1000BASE-LX/LH	-3	-9.5	-3	-19
WS-G5487	1000BASE-ZX	5	0	-3	-23*

* The WS-G5487 1000BASE-ZX GBIC provides a minimum optical power budget of 21 dB. 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 figure. The optical loss measurement must be performed with a 1550-nanometer light source.
