HPE Aruba S3N94A 400G Transceiver Specifications & Features

Overview

The HPE Aruba Networking S3N94A provides 400Gbps optical connectivity for high-bandwidth data center and enterprise networking applications. Its PLR4 architecture uses four 100G PAM4 optical lanes at 1310nm and combines them through an MPO12 interface.

With a maximum reach of 10km over single-mode fiber, the S3N94A is designed for longer-reach 400G connections where a 500m DR4 or shorter-reach multimode solution is insufficient.

400Gbps Network Performance

The S3N94A provides a total aggregate data rate of 400Gbps, making it suitable for high-bandwidth backbone, spine-leaf and data center interconnect applications.

Its four-lane architecture uses 100G PAM4 per optical lane, allowing a single QSFP-DD module to deliver 400Gbps of aggregate network capacity.

PLR4 Optical Technology

The S3N94A uses PLR4 optical technology with four optical lanes operating at 1310nm. Each lane carries 100Gbps using PAM4 modulation.

HPE's Aruba transceiver documentation specifically lists the S3N94A as four lanes at 1310nm with 4 × 100G PAM4 over MPO12 APC single-mode fiber. :contentReference[oaicite:2]{index=2}

10km Single-Mode Fiber Reach

The S3N94A supports transmission distances of up to 10km / 6.21 miles over 9/125 µm single-mode fiber.

This reach makes the module suitable for longer data center links, campus-scale network interconnections and other deployments where short-reach multimode optics cannot provide sufficient distance.

MPO12 APC Connector

The S3N94A uses an MPO12 APC optical connector. HPE's technical documentation specifies MPO12 APC for this 400G PLR4 module. :contentReference[oaicite:3]{index=3}

The APC connector specification is important when selecting compatible fiber infrastructure. The mating cable and connector system should use the appropriate APC configuration specified for 400G optical connectivity.

Single-Mode Fiber

The S3N94A is designed for single-mode fiber (SMF) with a 9/125 µm fiber specification.

It should not be confused with short-reach 400G multimode solutions such as SR8. For a 10km PLR4 deployment, use compatible single-mode MPO12 APC fiber infrastructure.

QSFP-DD Form Factor

The S3N94A uses the QSFP-DD form factor, enabling 400Gbps connectivity in a compact, high-density pluggable module.

QSFP-DD is designed for high-density switching environments where significant bandwidth is required without using larger form-factor optical modules.

12W Power Consumption

HPE's Aruba transceiver guide lists the S3N94A with a required power specification of approximately 12W. HPE notes that optical power consumption can affect operating temperature for selected switches. :contentReference[oaicite:4]{index=4}

Before deployment, verify that the target switch supports the S3N94A and provides adequate thermal and power capacity for the installed optical configuration.

Data Center Applications

• 400G spine-leaf networking
• Data center backbone connectivity
• High-speed switch-to-switch links
• Data center interconnects
• Enterprise core networking
• Cloud infrastructure
• High-performance computing networks
• Server and storage network aggregation
• Longer-distance 400G fiber links

HPE Aruba Networking Compatibility

HPE's Aruba transceiver documentation lists S3N94A among supported 400G QSFP-DD optical modules. The HPE Aruba Networking transceiver guide identifies S3N94A as a 400G PLR4 MPO12 10km SMF transceiver and provides platform-specific compatibility information. :contentReference[oaicite:5]{index=5}

HPE's documentation also identifies software/firmware requirements for supported platforms. For example, the Aruba 9300S documentation associates S3N94A with specific supported software requirements. :contentReference[oaicite:6]{index=6}

Always verify the exact switch model, port type, software/firmware version and optical compatibility matrix before installation.

PLR4 vs DR4

HPE's transceiver guide specifies S3N93A at 500m and S3N94A at 10km, making PLR4 the appropriate option when a significantly longer single-mode fiber reach is required. :contentReference[oaicite:7]{index=7}

PLR4 vs LR4

HPE identifies both S3N94A PLR4 and S3N96A LR4 as 10km SMF solutions, but they use different optical connector architectures. :contentReference[oaicite:8]{index=8}

Fiber Compatibility

For a full 10km link, use compatible 9/125 µm single-mode fiber with MPO12 APC connectivity. HPE specifically lists SMF MPO12 APC for S3N94A. :contentReference[oaicite:9]{index=9}

Do not substitute an MPO12 UPC configuration without confirming optical compatibility. HPE's 400G documentation emphasizes APC connectivity for the applicable MPO interfaces. :contentReference[oaicite:10]{index=10}

High-Density Data Center Networking

The QSFP-DD form factor allows the S3N94A to deliver 400Gbps connectivity in a compact pluggable design. This makes it suitable for high-density switch deployments where rack space, port density and aggregate bandwidth are important considerations.

It can be used in spine-leaf architectures, high-capacity aggregation layers and data center interconnect applications where compatible HPE Aruba networking equipment is deployed.
