Transceiver OSFP BlueOptics 980-9I51S-F4NS00 MPO-MTP-12/APC Flat Top 400GBASE-VR4 Multimode 850nm 50m DDM

The BlueOptics OSFP transceiver 980-9I51S-F4NS00 is a 400G multimode optical module designed for short-reach data center links. It supports the 400GBASE-VR4 IEEE standard, operates at a wavelength of 850 nm and uses an MPO/MTP-12 APC flat-top interface for multi-fiber connections. The module is intended for OM3 and OM4 multimode fiber and provides reliable transmission up to 50 meters. Digital diagnostic monitoring (DDM) enables real-time status reporting of optical and electrical parameters, and the transceiver is specified to operate across a 0°C to +70°C temperature range.

Advantages

This OSFP transceiver offers a compact OSFP form factor suitable for high-density switch and router ports, enabling 400 Gbps links over multimode fiber with MPO/MTP-12 connectivity. The 850 nm VCSEL-based optics provide stable short-range performance on OM3/OM4 fiber, while the APC flat-top MPO/MTP interface reduces back-reflection and supports multi-fiber ribbon connections. Built-in DDM delivers live monitoring of temperature, optical power, and voltage for easier diagnostics and maintenance in data center environments.

Key specifications

How to use

Install the transceiver into a compatible OSFP port according to the host device manufacturer’s instructions, ensuring the module is fully seated and latched. Use OM3 or OM4 multimode fiber cable terminated with an MPO/MTP-12 APC flat-top connector, and observe correct polarity and ribbon alignment when making the connection. After insertion, verify link status and monitor DDM parameters via the host system or management interface to confirm optical power, temperature, and voltage are within expected ranges.

Recommendations

For optimal performance, use high-quality OM3 or OM4 multimode cable and maintain clean MPO/MTP-12 APC connectors; inspect and, if necessary, clean connector endfaces before mating. Keep transceiver operating temperatures within the specified 0°C to +70°C range and follow the switch or router vendor guidance for OSFP module firmware compatibility and supported transceiver lists.
