400Gbps Data Center Connectivity

The S3N93A is designed for modern data center networks requiring very high bandwidth between switches, aggregation layers and other high-performance networking infrastructure.

With an aggregate data rate of 400Gbps, it can support demanding east-west traffic environments, high-performance computing networks, cloud infrastructure and data-intensive enterprise applications.

DR4 Optical Architecture

The DR4 architecture uses four optical lanes operating at 100G PAM4 each. HPE specifies the S3N93A as four lanes at 1310nm using 4 × 100G PAM4. :contentReference[oaicite:2]{index=2}

This architecture provides a 400Gbps aggregate link while maintaining a parallel optical design suitable for data center connectivity.

1310nm Single-Mode Fiber

The S3N93A operates at 1310nm over single-mode fiber. HPE specifies 9/125 µm SMF for this transceiver. :contentReference[oaicite:3]{index=3}

Single-mode fiber provides low-loss optical transmission and is suitable for high-speed data center links requiring a longer reach than typical multimode short-reach optics.

MPO12 APC Connector

The S3N93A uses an MPO12 APC connector. HPE's transceiver documentation specifies the connector as SMF MPO12 with an angled physical contact (APC) interface. :contentReference[oaicite:4]{index=4}

Use the appropriate MPO12 APC fiber infrastructure and verify connector polarity and fiber configuration before installation.

500 Meter Reach

The specified maximum distance for the S3N93A is 500 meters over single-mode fiber. HPE lists the reach as 500m (1,640.42 ft). :contentReference[oaicite:5]{index=5}

The actual achievable distance depends on fiber quality, connector loss, optical budget, patch panels, environmental conditions and the equipment at both ends of the link.

Digital Optical Monitoring

The S3N93A supports Digital Optical Monitoring (DOM). HPE's transceiver guide identifies DOM as available for the module. :contentReference[oaicite:6]{index=6}

DOM can provide useful optical and module telemetry for monitoring link conditions and troubleshooting supported network deployments.

12W Power Consumption

HPE specifies a required power level of approximately 12W for the S3N93A. :contentReference[oaicite:7]{index=7}

Because 400G QSFP-DD optics can generate significant heat, verify the supported switch model's thermal restrictions and airflow requirements before deploying multiple high-power optical modules.

400G QSFP-DD Form Factor

The S3N93A uses the QSFP-DD form factor, providing a compact pluggable interface for 400Gbps networking equipment.

QSFP-DD allows high-density 400G connectivity in compatible switches and network platforms while maintaining a pluggable optical architecture for serviceability.

400G DR4 Breakout Capability

HPE documents the S3N93A as capable of being split to lower-speed optical connections using the appropriate breakout configuration. The official Aruba transceiver guide states that 400G DR4 can use SMF MPO12 to four LC connections, with each breakout using two fibers, and can connect to supported 100G DR or 100G FR1 optics. :contentReference[oaicite:8]{index=8}

Not every QSFP-DD port supports breakout, so the exact switch model and port configuration must be checked before planning a 400G-to-4×100G deployment.

HPE Aruba Networking Compatibility

The S3N93A is an HPE Aruba Networking optical module intended for compatible Aruba networking platforms. HPE provides the module through its official networking transceiver portfolio under product number S3N93A. :contentReference[oaicite:9]{index=9}

Always verify the exact switch model, software version, port type and supported transceiver list before installation.

Applications

• 400G data center switching
• High-speed spine and leaf networks
• Data center interconnects
• Enterprise core networking
• Cloud infrastructure
• High-performance computing
• AI and GPU networking infrastructure
• Large-scale storage networks
• High-bandwidth server aggregation
• 400G network breakout applications

S3N93A vs 400G FR4

The S3N93A is preferable when a 400G MPO12 DR4 connection with a 500m reach is appropriate, while the S3N95A FR4 uses duplex LC and provides a longer 2km reach. HPE lists both modules in its official transceiver guide. :contentReference[oaicite:10]{index=10}

Installation Considerations

• Verify the switch supports the S3N93A.
• Use compatible MPO12 APC single-mode fiber.
• Verify fiber polarity before installation.
• Ensure the optical link does not exceed the 500m specification.
• Check switch thermal and power limitations.
• Verify breakout support if using 4 × 100G connectivity.
• Use compatible optics at the far end of the link.
