OSFP transceiver BlueOptics P49386-001-BO, MPO/MTP-12 APC, flat Top, 400GBASE-VR4, multimode 850nm, 50m, DDM

The BlueOptics OSFP Transceiver P49386-001-BO is a hot-pluggable optical module designed for short-reach 400G data center links. It implements the 400GBASE‑VR4 specification over multimode fiber at 850 nm using an MPO/MTP‑12 APC connector with a flat-top ferrule, supporting link distances up to 50 m. The module includes Digital Diagnostic Monitoring (DDM) and is specified to operate in ambient temperatures from 0°C to +70°C, making it suitable for standard data center environments requiring high-density, high-throughput interconnects.

Advantages

This transceiver supports 400GBASE‑VR4 multimode operation with an MPO/MTP‑12 APC interface and flat-top ferrule, enabling reliable high-speed transmission for short-reach applications. Built-in DDM provides real-time monitoring of optical and electrical parameters to aid maintenance and fault diagnosis. The module’s OSFP form factor offers high port density and hot-pluggable convenience while the operating temperature range of 0°C to +70°C aligns with typical data center conditions.

Suitable for

When it may not be suitable

This transceiver is intended for multimode fiber at 850 nm and short links up to 50 m; it is not suitable for single-mode long-reach applications or links that require distances beyond the specified 50 m. Systems that require different connector types, non‑APC ferrules, or other form factors (for example QSFP, CFP, or fixed SFP variants) will not be compatible without appropriate adapters or chassis that accept OSFP modules.

Key specifications

How to use

Install the OSFP transceiver into a compatible OSFP slot on the switch or router while the host system is powered according to the equipment manufacturer’s hot-plug guidelines. Connect MPO/MTP‑12 APC multimode fiber patch cords with a matching flat-top ferrule to the module, ensuring correct polarity and secure seating. After insertion and cable connection, verify the link status and monitor DDM parameters through the host system’s management interface to confirm optical power, temperature, and other diagnostics are within expected ranges.

What to consider before purchase

Recommendations

Use factory-certified MPO/MTP‑12 multimode patch cords and maintain clean connector endfaces to preserve signal integrity. Monitor DDM values after deployment to detect degradation early, and replace or re-terminate fiber segments if measured power levels or error counters indicate problems.
