The 3.125 Gigabit Ethernet 1530 nm CWDM Small Form-Factor Pluggable (SFP) is a single-mode fiber SFP
that plugs into ADTRAN Gigabit Ethernet modules designed to accept SFPs. The SFP provides a dual optical
interface to a 3.125 Gigabit Ethernet physical interface. Installed into an appropriate module, the SFP provides a 3.125 Gigabit Ethernet tributary interface to the supporting system.
