Overview

Pervasive bandwidth requirements due to the tremendous growth in wireless devices are the catalyst for large-scale (200 Gbps) system designs in server farms. zQSFP+ connectors transmit up to 28/56 Gbps per-serial-lane data rates with excellent signal integrity, relieving some of the pressure on core switches.

The operating power for plugs was increased from 3.5 to 5W. The increased wattage also increased the heat generated, necessitating a thermally enhanced component to manage that extra heat. zQSFP+ Interconnect System with thermal protection offers three options to manage heat: a through-flow cage optimized to allow airflow through the midsection of the cage, an internal riding heat sink, and a top-riding heat sink to help increase airflow and manage the additional heat generated by the 5-watt plugs.
