Transceiver module NVIDIA QSFP112 400GbE MPO single-mode 1310 nm up to 500 m

NVIDIA QSFP112 400GbE MPO single-mode transceiver module operates at 1310 nm and supports optical links up to 500 m. Designed for high-density data center and backbone interconnects, the module provides multi-lane 400GbE transmission over single-mode fiber using an MPO connector. It is intended for interoperability with compatible switches and adapters that accept QSFP112 form-factor optics and supports reliable long-reach optical connectivity for aggregation and spine links.

Advantages

This NVIDIA QSFP112 transceiver delivers 400GbE bandwidth in a compact QSFP112 form factor, enabling higher port density in optical aggregation and spine deployments. Single-mode operation at 1310 nm allows extended reach up to 500 m over single-mode fiber, while the MPO interface simplifies multi-lane connections. The module is suitable for environments that require predictable optical performance, compatibility with industry-standard QSFP112 ports, and stable long-reach links for core data center paths.

Suitable for

• Data center spine and leaf interconnects requiring 400GbE bandwidth
• Short to medium-range backbone links up to 500 m over single-mode fiber
• High-density switch and router ports using QSFP112 optics
• Aggregation switches and optical interconnects in enterprise and service provider networks

When it may not be suitable

This single-mode QSFP112 module is not intended for multimode fiber installations or for links that require distances beyond 500 m without additional amplification or regeneration. It may not be appropriate where different wavelength plans or connector types (for example LC duplex) are required by existing infrastructure. Ensure the target equipment explicitly supports QSFP112 optics and the MPO connector before deployment.

How to use

Install the NVIDIA QSFP112 transceiver into a compatible QSFP112 port on switches or adapters following standard hot-pluggable optics procedures. Connect the MPO-terminated single-mode fiber cable, ensuring correct polarity and secure mating of the MPO connectors. Verify link status and negotiate 400GbE operation via the host device management interface. Monitor temperature and optical parameters through the host for stable operation and consult the switch vendor documentation for any required transceiver compatibility settings.

What to consider before purchase

• Confirm that your switch or adapter supports QSFP112 form-factor transceivers and MPO connectors
• Verify network fiber type is single-mode and supports 1310 nm wavelength
• Check required link distance to ensure the 500 m maximum meets your topology needs
• Ensure compatibility with your vendor’s optics policy and any firmware requirements

Recommendations

Use high-quality single-mode MPO trunk cables with proper polarity and follow vendor guidelines for optical power budgets. Validate links after installation and perform end-to-end testing for BER and throughput to confirm 400GbE performance. Keep firmware and transceiver compatibility lists up to date to maintain reliable operation.
