The SFP cage provides a physical interface and mechanical support for the SFP module, allowing it to be easily inserted and removed without powering down the networking equipment. The primary purpose of the SFP cage is to ensure proper alignment and connection of the SFP module with the device's electrical and optical interfaces. This allows for the efficient transmission of data between network devices. The cage also helps protect the delicate components of the SFP module from physical damage and ensures a reliable and consistent connection.

Heat Sink

The heat sink increases the surface area available for heat dissipation and facilitates the transfer of heat away from the SFP module to the surrounding environment.

Light Pipe

An SFP light pipe is a component designed to guide and transmit the indicator light from an SFP module to the front panel of networking equipment to indicate various status information, such as link activity, data transmission, and module status.
