They connect network devices (like switches, routers, and servers) to fiber optic or copper cables, enabling high-speed data transmission over short or long distances, while GE SFP Optical Modules (Gigabit Ethernet Small Form-factor Pluggable) are a type of fiber optic transceiver.

Use Germanium's unique combination of high refractive index and excellent hardness to build durable, low-power imaging and laser systems with a minimum component count. Germanium (Ge) is ideal for applications where ruggedness and durability are important, and Ge optics can withstand optical powers. An optical module is a component that completes electrical/optical conversion on an optical network. Figure 3-198 shows the structure of an optical module. SFP Optical Modules (Small Form-factor Pluggable) are compact, hot-swappable transceivers used for telecommunication and data communication applications. The optics feature a twist-lock interface for easy, tool-free attachment to the Infusion module.
