Inserting and Removing Optical Modules: When inserting or removing optical modules, gently insert the module into the slot, ensuring proper alignment of the interface. Common types of optical modules include SFP, SFP+, SFP28, QSFP, QSFP28, etc. However, you might need to refer to the datasheet or user manual of any new transceivers to familiarize yourself with their properties and the latching mechanism. ● Avoid allowing dust and other contaminants to enter the optical bores of the SFP or SFP+ module because the optics do not function properly when blocked by dust. After removing the optical cables, protect them by. This section describes how to install an optical module.
