Cisco has been pioneering several initiatives to bring new Ethernet technologies to market. These include Cisco® 25GBASE Small Form-Factor Pluggable SFP28, Cisco 100GBASE Quad Small Form-Factor Pluggable QSFP28, and more importantly, dual-rate optics along with the latest Cisco Catalyst® 9000 switching family to facilitate such network speeds and architecture transformations. These innovations enable flexible options and backward compatibility to drive network speeds beyond the current 10G and 40G capabilities while minimizing cost and real estate changes. With a prevalidated architecture, Cisco’s Enterprise Networks portfolio can help forward-thinking enterprises that wish to build a network infrastructure that offers flexibility and scale. This white paper highlights some of the key aspects of these new Ethernet standards, and the benefits of 25G and 100G in campus networks. It also documents use cases involving high-speed network transitions that are extending link lengths for 25G to 300m over duplex Multi Mode FIber (MMF) optical Mode 3(OM3) (400m over OM4) as well as provides details of supported Cisco’s platforms.
