SFP-GE-L-ALT is a Gigabit Ethernet SFP (Small Form-Factor Pluggable) optical transceiver, designed for long-distance fiber connectivity over single-mode fiber (SMF).
The “ALT” designation indicates this is an alternate or third-party compatible version, not an original Cisco-branded module, but intended to work in Cisco equipment (e.g., Catalyst switches, routers).
It is commonly used to connect switches over long distances (up to ~10 km) using 1000BASE-LX/LH optical standard.
