Key Features

The QSFP-40G-SR4-S is a Cisco S-Class 40GBASE-SR4 QSFP+ transceiver designed for high-bandwidth optical links over multi-mode fiber, supporting 40 Gigabit Ethernet. It uses parallel optics via an MPO/MTP connector and is designed for high port density and low power consumption in data center and enterprise environments. It is specifically noted for *not* supporting 4x10G breakout connectivity, differentiating it from the standard QSFP-40G-SR4.
