065-79LXMG Small Form-factor Pluggable (SFP) Gigabit Interface Module

The Signamax 065-79LXMG is a Small Form-factor Pluggable (SFP) singlemode fiber module that supports

Gigabit Ethernet over singlemode fiber cable at distances up to 10 kilometers. It adheres to the IEEE 802.3z

standard for Gigabit Ethernet over singlemode fiber at 1310 nm, and is a cost-effective method of providing

changeable Gigabit Ethernet singlemode interfaces to switches and media converters equipped with a standard

SFP slot.
