Installing a QSFP28 optical module 400G
Utilizing breakout technology, such as QSFP-DD to 4xQSFP28, is the most important technical means for achieving a seamless upgrade from 100G to 400G. Before upgrading, it is essential to evaluate whether the existing fiber types (OM4/OM5/single-mode) and connectors (MPO. Page 2 Preface Audience: This installation note provides instructions for installing FS Quad Small Form-factor Pluggable 28 (QSFP28) and Small Form-factor Pluggable Double Density (SFP-DD) transceiver modules. These modules are hot- swappable input/output (I/O) devices that plug into 100GBASE. In this evolving landscape, QSFP28 PAM4 DWDM (Dense Wavelength Division Multiplexing) emerges as a practical and high-performance solution for extending 100G and 400G signals across metro, campus, and inter-data-center links. Optical modules are classified by their packaging forms, with common types including SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD, QSFP112, and. Originally designed for 40G Ethernet (QSFP+), they have evolved to support 100G, 200G, and 400G speeds with new standards like QSFP28 and QSFP-DD.

Check the duplex mode of the access switch
The switches that run Cisco IOS Software default to auto-negotiation for speed and are set to on for the duplex. The switches can also set their duplex setting with the duplex interface subcommand, and their speed with—you guessed it—the speed interface subcommand. This is only applicable for 10/100/1000 Mbps (1000BASE-T) NICs only Assuming maximum capability of Catalyst switch, and NIC is 1000 Mbps, full-duplex. I would like to know what duplex (half or full) my network card has negotiated with a switch when they are both set to auto configuration in Windows.
