Transceptor BlueOptics MMA4Z00-NS400-T-BO OSFP, MPO-MTP-12/APC, 400GBASE-VR4, multimodo 850 nm, 50 m, 0–70°C, DDM

BlueOptics MMA4Z00-NS400-T-BO is an OSFP 400G transceiver module compatible with NVIDIA MMA4Z00-NS400-T. Designed for short‑reach, high‑capacity links in data center and enterprise networks, this multimode 850 nm module supports 400GBASE‑VR4 over MPO‑MTP‑12/APC connectivity and reaches up to 50 meters. The module operates across an ambient temperature range of 0–70°C and provides Digital Diagnostic Monitoring (DDM) for real‑time status and optical parameter reporting.

Advantages

The transceiver offers high-density 400 Gbit/s throughput in an OSFP form factor, enabling consolidation of multiple 100G links and reducing port count. Using multimode fiber and 850 nm optics provides cost‑effective short‑reach connectivity while the MPO‑MTP‑12/APC connector ensures reliable multi‑lane alignment. Integrated DDM allows monitoring of operating temperature, optical power and signal integrity to assist in maintenance and troubleshooting.

Key specifications

How to use

Install the OSFP transceiver into a compatible OSFP cage on a switch or network adapter while the host device is powered down or following the vendor’s hot‑swap instructions. Connect MPO‑MTP‑12/APC multimode fiber trunks that comply with the cabling plan and ensure correct polarity and lane mapping for 400GBASE‑VR4. After insertion, verify link status and monitor optical parameters via the host system to confirm proper operation.

Recommendations

For reliable performance, use OM4 or higher grade multimode fiber, maintain clean MPO‑MTP connectors and observe proper insertion/removal procedures. Check compatibility lists for OSFP module support on your switch or NIC and use DDM readings to detect deviations in optical power or temperature that may indicate connector contamination or fiber bends.
