What This Is NOT
NOT a cable. Pluggable optical transceiver — pair with an MPO-12/APC multimode patch cord or trunk.
NOT a splitter / breakout. Single-port QSFP112 only; no fan-out to 2× 200G or 4× 100G in this MPN.
NOT single-mode. 850 nm VCSEL multimode optics only — does not operate on OS2 single-mode fiber.
NOT bundled with patch cables, cassettes, cleaning kits, or breakout harnesses.
Compatibility & Constraints
InfiniBand switches: NVIDIA Quantum-2 NDR platforms whose ports support QSFP112 (native QSFP112 cages, or via OSFP-to-2× QSFP112 hybrid topologies when called for).
Ethernet switches: NVIDIA Spectrum-4 400GbE platforms with QSFP112 cages.
Adapters: NVIDIA ConnectX-7 NDR / 400GbE adapters with QSFP112 ports; NVIDIA BlueField-3 DPUs with QSFP112 network ports.
Fiber plant: OM4 multimode with MPO-12/APC connectors. OM3 supported at shorter reach (≤ 30 m).
Cleaning: MPO end-faces require periodic cleaning per IEC 61300-3-35; APC polish is mandatory.
Firmware: Verify host and switch firmware support the relevant CMIS revision and the intended port mode (IB vs Ethernet) before deployment.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MMA1Z00-NS400?
The MMA1Z00-NS400 is a 400 Gb/s NDR InfiniBand and 400GbE Ethernet multimode optical transceiver in QSFP112 form factor with an MPO-12/APC fiber connector, rated for up to 50 m on OM4 multimode fiber. It uses four 100 Gb/s PAM4 lanes (4×100G) and is part of the NVIDIA LinkX NDR optical portfolio for Quantum-2 and Spectrum-4 platforms.
Q. What fiber type and reach does the MMA1Z00-NS400 support?
The MMA1Z00-NS400 is a multimode SR4-class transceiver that operates on OM4 multimode fiber up to 50 m and on OM3 up to roughly 30 m, using an MPO-12/APC parallel fiber connector. It does not operate on single-mode (OS2) fiber.
Q. What hardware is the MMA1Z00-NS400 compatible with?
Switch side: NVIDIA Quantum-2 NDR InfiniBand switches with QSFP112 cages and NVIDIA Spectrum-4 400GbE Ethernet switches with QSFP112 cages. Adapter side: NVIDIA ConnectX-7 NDR / 400GbE adapters and BlueField-3 DPUs with QSFP112 network ports. Verify CMIS firmware, port mode (IB vs Ethernet), and fiber plant before deployment.
Q. Where is the MMA1Z00-NS400 typically deployed?
Typical use cases are intra-row and inter-rack 400G NDR / 400GbE optical links in HPC and AI clusters — leaf-to-spine and spine-to-core hops up to 50 m where MPO-12/APC multimode plant is already in place. For reaches beyond 50 m, single-mode parallel or duplex DR/FR optics should be used instead.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished Grade A. Each MMA1Z00-NS400 is bench-tested by T.E.S IT-SOLUTIONS — EEPROM / vendor-data check, link establishment, DDM readout, and cosmetic inspection of MPO end-faces. Units ship from EU stock in professional anti-static packaging with global B2B shipping. Pre-sale compatibility advice for Quantum-2, Spectrum-4, ConnectX-7, and BlueField-3 platforms is included.
