25GB for Enterprise Campus Networking System-Upgrade it:

Enterprise campus networking systems are trying to support growing bandwidth-hungry endpoint. Networks support the devices that provide advanced technology like Wi-Fi 6 and richer content such as HD video. Enterprise future-proofs its network with extensive bandwidth while reducing invasive changes via moving to 25GB connections between the access and aggregation switches. 25GB provides 2.5 times a 10 Gigabyte lane's bandwidth and gives an ideal upgrade to 100GB. Enhancement to 25GB allows for reusing current cabling, decreasing CAPEX. Nevertheless, there are several advanced types of 25GB. This writing will examine the economics between 25GB and 10GB.
We have designed the modern Catalyst 9500 serial switches for aggregation applications and enterprise core networks. Cisco Catalyst 9300 serial stackable switches, including port-4 25GB networking uplink modules, provide connectivity of 25GB from an access network to an aggregation network. With Cisco optics and Catalyst 9300/9500, IT staff deploys a networking fabric with a bandwidth of 25GB without replacing and ripping cables. We have given below an enterprise networking architecture example involving Catalyst 9500 within the aggregation network and Catalyst 9300 within the access network.

Moreover, the price difference between using 25GB VS 10GB is tiny. Catalyst 9300 and 9500 25GB ports also work at 10GB. So, users can choose to utilize 25GB or 10GB optics within 25GB ports. Nevertheless, 25GB optics' additional cost adds just one percent to the BOM's total price. For comparison, we have given two Bills of Material (BOMs) for effective campus implementation at the enterprise that handles 5,000 people.

The advantages of the bandwidth of 25GB outweigh any financial regard. For IT organizers, the option is obvious, 25GB fiber optics give a 150% expansion within bandwidth for just one percent increase in price.
