The Cisco QSFP-DD-400G-SR4-2 is a 400 Gbps optical transceiver in the QSFP-DD (Quad Small Form Factor Pluggable Double Density) interface type. It is designed for 400GBASE-SR4 links over multimode fiber, operating at a wavelength of 850 nm.
This module supports a reach of 100 m over OM3 multimode fiber. It operates within a temperature range of 0–70 °C, with a typical power consumption of 3.5 W.
As a short-reach multimode optic, the QSFP-DD-400G-SR4-2 is typically used for high-bandwidth connections inside data centers, such as links between switches, routers and other network equipment within the same room or across nearby racks with QSFP-DD ports.
