Transceiver and Cabling Options

The Cisco Nexus 3172 switches support a wide variety of 1, 10, and 40 Gigabit Ethernet connectivity options.1 and 10 Gigabit Ethernet connectivity is achieved in the first 48 ports, and 40 Gigabit Ethernet connectivity is achieved using QSFP+ transceivers in the last 6 ports.

QSFP+ technology allows a smooth transition from 10 to 40 Gigabit Ethernet infrastructure in the data center. The Cisco Nexus 3172 switches support connectivity over copper and fiber cables, providing excellent physical-layer flexibility. For low-cost cabling, copper-based 40-Gbps Twinax cables can be used, and for longer cable reaches, short-reach optical transceivers are excellent.

Connectivity can be established from the QSFP ports to an upstream 10 Gigabit Ethernet switch using a splitter cable that has a QSFP transceiver on one end and four SFP+ transceivers on the other end. Similar capability can be achieved using optical transceivers by procuring third-party fiber splitters. In addition, 1G and 10G interfaces can be supported on QSFP ports with the Cisco CVR-QSFP-SFP10G adapter.
