Cisco Rugged SFP - SFP (mini-GBIC) transceiver module - 1GbE - 1000Base-LX, 1000Base-LH - LC single-mode - 1310 nm - for Cisco 3270, 3270 Rugged Integrated Services Router Card, Catalyst ESS9300 Embedded Series

The industry-standard Cisco Small Form-Factor Pluggable (SFP) transceiver modules are hot-swappable input/output (I/O) devices that plug into 100BASE, 1000BASE and 10GBASE ports (for SFP+), which connect the module port with the fiber-optic or copper network.¦The 1000BASE-LX/LH SFP transceiver module for SMF, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard singlemode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable.
