QSFP112-transceiver NVIDIA MMA1Z00-NS400 400GbE MPO-12 850nm

QSFP112 transceiver NVIDIA MMA1Z00-NS400 400GbE MPO-12 850nm is a 400 Gigabit Ethernet optical module intended for use over multimode fiber. The module features an MPO-12 connector and operates at an 850 nm wavelength to enable short-reach 400GbE links. It is designed for high-density data center and switching environments, offering a compact, hot-pluggable form factor suitable for aggregation, spine-leaf and server interconnects.

Advantages

The transceiver delivers high-bandwidth connectivity in a compact QSFP112 package compatible with systems that support 400GbE over multimode fiber. Its MPO-12 interface simplifies cabling for parallel optics, while the 850 nm wavelength is optimized for multimode fiber short-reach links. The hot-pluggable design allows insertion and removal without powering down the host equipment, enabling flexible maintenance and upgrades in dense rack environments.

Suitable for

• Data center aggregation and top-of-rack switching
• Spine-leaf network architectures
• High-density server interconnects and switch-to-switch links
• Short-reach multimode fiber links within a campus or data hall

How to use

Install the transceiver into a compatible QSFP112 port on a switch or server following the host vendor's installation procedure. Connect the MPO-12 multimode fiber cable to the module, ensuring proper orientation and connector cleanliness to maintain signal quality. Verify link status through the host equipment's management interface and monitor diagnostics if available. Remove the transceiver by following hot-swap procedures provided by the equipment manufacturer.

Recommendations

Use OM3 or OM4 multimode fiber with appropriate MPO-12 trunking to achieve the expected short-reach performance. Keep MPO connectors clean and protected with dust caps when not in use. Confirm compatibility with the host device firmware and optical specifications before deployment, and follow the data center's cabling and ESD handling policies during installation and maintenance.
