Dell Q56DD-400G-EDR4 – QSFP-DD EDR4 Optical Transceiver

About Dell Q56DD-400G-EDR4 QSFP-DD EDR4 Optical Transceiver in Bangladesh

The Dell Q56DD-400G-EDR4 is a high-speed 400Gbps optical transceiver designed for next-generation Ethernet networking, data center infrastructure, AI clusters, cloud platforms, and high-performance computing environments. Using the compact QSFP-DD form factor and EDR4 optical architecture, it provides high-bandwidth connectivity over single-mode fiber.

The Q56DD-400G-EDR4 uses four optical lanes operating at approximately 100Gbps per lane with PAM4 modulation to deliver an aggregate 400Gbps data rate. Its 1310nm optical technology and single-mode fiber design make it suitable for medium-reach optical connections in modern data center and enterprise network environments.

With a duplex LC optical interface, the transceiver provides a practical point-to-point fiber connection for compatible 400GbE networking platforms. It is suitable for high-capacity switch-to-switch links, spine-leaf network fabrics, AI and GPU infrastructure, data center interconnects, and other compatible 400GbE applications.

Dell Q56DD-400G-EDR4 QSFP-DD EDR4 Optical Transceiver Specifications & Overview

Overview

The Dell Q56DD-400G-EDR4 delivers 400Gbps optical Ethernet connectivity in a high-density QSFP-DD form factor. It is designed for modern data centers where high throughput, efficient port density, and reliable optical connectivity are essential.

The EDR4 architecture uses four parallel optical lanes, with each lane carrying approximately 100Gbps using PAM4 modulation. Together, the four lanes provide an aggregate 400Gbps optical connection while maintaining a compact pluggable form factor.

Operating at the 1310nm optical wavelength over single-mode fiber, the EDR4 design is intended for medium-reach optical links. A reach of up to approximately 2km makes it suitable for connections within and between data center facilities, depending on the complete optical link and installation conditions.

The duplex LC interface provides a straightforward point-to-point connection using standard duplex single-mode fiber infrastructure, making it suitable for deployments where parallel-fiber cabling is not preferred.
