SFP-GE-S Modules

The 1000BASE-SX (short wavelength) module operates on standard multimode fiber-optic link spans of
up to 500m on 50/125um MMF and 300 m on 62.5/125um MMF.

SFP-GE-L Modules

The 1000BASE-LX/LH (long wavelength/long haul) module interfaces fully comply with the IEEE
802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles (10
km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.

SFP-GE-Z Modules

The 1000BASE-ZX (extended wavelength) module operates on ordinary single-mode fiber-optic link
spans of up to 49.7 miles (80 km). Link spans of up to 62.1 miles (100 km) are possible using premium
single-mode fiber or dispersion-shifted single-mode fiber (premium single-mode fiber has a lower
attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has
both lower attenuation and less dispersion).
The 1000BASE-ZX module must be coupled to single-mode fiber-optic cable, which is the type of cable
typically used in long-haul telecommunications applications. The 1000BASE-ZX module will not
operate correctly when coupled to multimode fiber, and it is not intended to be used in environments
where multimode fiber is frequently used (for example, building backbones, or horizontal cabling).
The 1000BASE-ZX module is intended to be used as a Physical Medium Dependent (PMD) component
for Gigabit Ethernet interfaces found on various switch and router products. It operates at a signaling
rate of 1250 Mbaud, transmitting and receiving 8B/10B encoded data.
