The StarTech QSFP-400G-DR4-ST is a 400Gbps QSFP-DD optical transceiver module designed for single-mode fiber (SMF) connections. It provides a direct replacement for Cisco QDD-400G-DR4-S, enabling high-speed data transmission up to 500 meters. This module is critical for expanding network capacity in data centers and high-performance computing environments where bandwidth demands are paramount. Its 1310nm wavelength and full-duplex operation ensure efficient data flow for demanding applications.
This QSFP-DD module is engineered to be compatible with Cisco networking equipment that supports the QDD-400G-DR4-S standard. It adheres to IEEE 802.3bs 400GBASE-DR4 industry standards, ensuring interoperability with other compliant network devices and switches operating at 400 Gbps. Verify your switch or router port compatibility for QSFP-DD form factor and DR4 signaling.
The QSFP-400G-DR4-ST operates within a standard 0°C to 70°C temperature range, suitable for most controlled indoor environments. It draws a maximum of 12W, which is important for managing power budgets in dense switch deployments. The module's compact dimensions (4.6 x 0.7 x 0.5 inches) facilitate installation in standard QSFP-DD ports. Ensure proper handling to avoid electrostatic discharge during installation.
