This switch is equipped with 48 SFP+/SFP28 ports (1G/10G/25G) and 6 QSFP+/QSFP28 (40G/100G) ports. For example, high speed financial trading applications can be optimized for the lowest possible latency. The 34180YC is programmable allowing the user to customers to tailor packet forwarding behavior to the needs of their applications. This switch offers great flexibility in ports speeds, covering 1G, 10G, 25G, 40G and 100G rates. The Nexus 34180YC is an ideal switch to demonstrate the used of the FluxLight brand, Cisco compatible SFP-25G-SR-S transceiver. Across this family of products essentially all available rates of optical ethernet are offer, from 1G to 400G. All members are compact (1RU) fixed configuration products. The 3000 series is squarely targeted for ToR applications. The Nexus 3400 platform is part of the latest generation of the fixed Nexus®3000 Series Switches. The only other pieces required are FluxLight SFP-25G-SR-s multimode transceivers and OM4 multimode patch cables. To depict this application with real-world products, a ToR switch from Cisco’s Nexus 3000 series and a rack-mounted server from Supermicro have been selected. These connections may be constructed using 25Gbps Direct Attached Copper cables (DACs), Active Optical Cables (AOCs), or with a pair of SFP28 25Gbps optical transceivers and an appropriate duplex fiber optic jumper cable. Many hyperscale data centers and even larger enterprise data centers are migrating these access links to 25Gbps. For the past five to seven years the most common speed of connection between a Top of Rack (ToR) leaf switches to subtending computer and storage servers has been 10Gbps.
