The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The objective of this article is to provide an overview of small form-factor pluggable (SFP) and SFP plus (SFP +) modules supported on the Cisco Business Switches (CBS) and some general tips to choose and use them effectively for uninterrupted network function. This document also shows you tips to view the most up to date list of modules.
The SFP transceiver modules are hot-pluggable input/output devices that plug into dedicated sockets. The transceiver connects the electrical circuitry of the device with the external optical or copper network to extend routing and switching functionality throughout the network. The transceiver facilitates specialized high-speed communication over long distances such as different buildings on a campus or multiple floors in the same building depending on your network. These transceivers provide connectivity where traditional 10BASE-T, 100BASE-TX, 1000BASE-T Ethernet Cat6 network cabling cannot be used.
Often, these modules are also casually called a mini Gigabit Interface Converter (GBIC). A GBIC module is also a transceiver module but technically is not an SFP form-factor and cannot be inserted into an SFP port as they are bigger in size.
SFP Plus (SFP +) module is an updated version of SFP supporting higher data speeds.
To find the list of modules supported by Cisco Business switches, you may refer to the product Data Sheet or the Administration Guide. The latest information is available through the site mentioned below in Step 1.
Open a web browser and access the Transceiver Module Group compatibility matrix URL.
In the search window, type the name of the switch and click enter on your keyboard. Alternatively, you can choose the name of your switch model from the options that auto-populate as you start typing in the search bar.
(Optional) You can choose to apply filters by selecting specific parameters from the options.
You can view the table listing the supported SFP/SFP + modules along with the description.
Click on the Product ID of a specific SFP module to access the Data Sheet.
There you go! You have now viewed the comprehensive list of SFP and SFP + modules supported by CBS that can help you select the one best suited for your network.
