2-Port Gigabit Ethernet SPA Overview
SFP-GE-S Modules
The 1000BASE-SX (short wavelength) module operates on standard multimode fiber-optic link spans of
up to 500 m 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
Extended wavelength
(1000BASE-ZX)
Contains a Class 1 laser of 1550 nm for
1000BASE-ZX (extended wavelength)
applications.
SFP-GE-T
RJ-45 copper SFP module
(1000BASE-T)
Provides full-duplex Gigabit Ethernet
connectivity to high-end workstations and
between wiring closets over an existing copper
network infrastructure.
