Aruba QSFP-DD 400GBASE-DR4 – QSFP-DD DR4 Optical Transceiver

About Aruba QSFP-DD 400GBASE-DR4 Optical Transceiver in Bangladesh

The HPE Aruba Networking 400G DR4 QSFP-DD MPO12 500m SMF Transceiver is a high-performance 400Gbps optical transceiver designed for modern data center, enterprise, AI, cloud, and high-performance computing networks. The official HPE product reference is S3N93A.

Using the 400G DR4 optical architecture, the transceiver provides four parallel 100Gbps PAM4 optical lanes over single-mode fiber. It operates at a 1310nm optical wavelength and uses an MPO-12 APC connector, providing a high-bandwidth solution for compatible Aruba and HPE Networking platforms.

With a maximum specified distance of 500 meters, the Aruba 400GBASE-DR4 transceiver is suitable for short-to-medium reach single-mode fiber connections inside data centers and enterprise facilities. Typical applications include leaf-to-spine networking, switch-to-switch connectivity, AI and GPU clusters, high-performance computing, and data center aggregation.

Aruba QSFP-DD 400GBASE-DR4 Optical Transceiver Specifications & Overview

Overview

The Aruba QSFP-DD 400GBASE-DR4 is designed to provide high-density 400GbE optical connectivity through a compact QSFP-DD interface. Its four-lane architecture uses 100G PAM4 signaling on each optical lane to deliver an aggregate 400Gbps data rate.

The transceiver operates at 1310nm over single-mode fiber and supports a maximum distance of 500 meters. This makes it particularly useful for data center environments where 400Gbps links need to span racks, rows, or other short-to-medium distances while maintaining high bandwidth.

The MPO-12 APC connector provides the parallel-fiber interface required by the DR4 architecture. Proper MPO polarity, connector type, fiber quality, and optical link configuration must be verified before installation.

HPE Aruba Networking specifies Digital Optical Monitoring (DOM) for the S3N93A, allowing supported network equipment to monitor relevant optical operating parameters. The published power requirement is 12W, with a commercial operating temperature range of 0°C to 70°C.
