OSFP Transceiver BlueOptics 980-9I51S-00NS00-BO, MPO/MTP-12 APC Flat Top, 400GBASE-VR4, Multimode 850nm, 50 m, 0–70°C, DDM

The BlueOptics OSFP transceiver 980-9I51S-00NS00-BO is a single-unit OSFP module designed for 400GBASE‑VR4 short‑reach links over multimode fiber. Compatible with NVIDIA OSFP form factor, this transceiver uses an MPO/MTP‑12 APC flat‑top connector and operates at 850 nm wavelength. It supports a nominal reach of up to 50 meters in data center environments and includes Digital Diagnostics Monitoring (DDM) for real‑time status and performance reporting. The module is specified for an operating temperature range from 0 to 70 °C, making it suitable for standard rack and hyperscale installations.

Advantages

This OSFP module provides high‑density 400 Gbit/s connectivity in a compact form factor and is compatible with systems that accept the NVIDIA OSFP standard. The MPO/MTP‑12 APC flat‑top interface ensures stable multi‑lane fiber connections while the multimode 850 nm optics are optimized for short links inside data centers. Integrated DDM enables monitoring of optical power, temperature, and other operating parameters to aid in diagnostics and maintenance. The specified 0–70 °C operating range supports deployment in standard cooled equipment racks.

Key specifications

How to use

Install the OSFP transceiver into a compatible NVIDIA OSFP slot following the host system manufacturer’s hot‑swap and handling procedures. Connect the multimode MPO/MTP‑12 APC flat‑top cable to the module, ensuring correct polarity and that the connector endface matches APC flat‑top requirements. Verify link establishment using the switch or host interface and monitor DDM parameters to confirm optical levels and temperature remain within expected ranges. Follow electrostatic discharge (ESD) precautions when handling the module and avoid touching fiber endfaces to prevent contamination.

Recommendations

For reliable 400GBASE‑VR4 operation, use OM3/OM4 multimode fiber rated for 850 nm and maintain a maximum link length of 50 meters. Clean connectors before mating and use compatible MPO/MTP‑12 APC flat‑top patch cords designed for multimode applications. Monitor DDM values periodically to detect signal degradation early, and deploy the transceiver in properly cooled racks to remain within the 0–70 °C operating range.
