Dell 800G QSFP-DD 2×FR4 – QSFP-DD 2×FR4 Optical Transceiver

About Dell 800G QSFP-DD 2×FR4 Optical Transceiver in Bangladesh

The Dell 800G QSFP-DD 2×FR4 is a high-capacity optical transceiver designed for next-generation 800Gbps Ethernet networking. Using a high-density QSFP-DD form factor and a 2×400G FR4 optical architecture, it provides high-bandwidth connectivity for modern data center, AI, cloud, and high-performance computing environments.

The 2×FR4 architecture combines two independent 400G FR4 optical links within a single module, providing an aggregate optical capacity of 800Gbps. FR4 technology uses four optical wavelengths in the 1310nm region and is designed for single-mode fiber connectivity.

The transceiver is intended for compatible Dell high-speed Ethernet switches, routers, spine-leaf fabrics, AI networking platforms, and data center interconnect equipment supporting the required 800GbE QSFP-DD interface and 2×FR4 optical configuration.

Actual compatibility, supported reach, connector configuration, breakout operation, power requirements, and host-platform support depend on the exact Dell transceiver part number and networking equipment. Always verify the manufacturer's compatibility documentation before deployment.

Dell 800G QSFP-DD 2×FR4 Optical Transceiver Specifications & Overview

Overview

The Dell 800G QSFP-DD 2×FR4 provides high-density 800Gbps optical connectivity using two 400G FR4 optical links within a single QSFP-DD module. It is designed for modern data center architectures where high throughput, efficient port density, and flexible optical connectivity are required.

FR4 optical technology uses four wavelengths in the 1310nm optical region and is designed for single-mode fiber. PAM4 modulation enables high data rates while maintaining an efficient optical architecture suitable for high-capacity Ethernet networking.

The 2×FR4 configuration enables two independent 400Gbps optical connections within one high-density module. This makes it suitable for high-performance spine-leaf networks, AI and HPC clusters, cloud infrastructure, aggregation networks, and data center interconnects.

Compared with short-reach multimode 800GbE optics, FR4 is designed for single-mode fiber and provides greater flexibility for high-bandwidth network links where single-mode fiber infrastructure is already available.
