BlueOptics OSFP lähetin-vastaanotin P49764-B21-BO, MPO-MTP-12/APC, flat top, 400GBASE-VR4, multimode 850 nm, 50 m, DDM

BlueOptics OSFP Transceiver P49764-B21-BO is a 400GBASE-VR4 multimode fiber module designed for short-reach high-density links in data center and carrier environments. The module uses an MPO-MTP-12/APC connector with a flat-top ferrule and operates at 850 nm over multimode fiber to deliver reliable 400 Gbit/s aggregate throughput for distances up to 50 meters. Built-in Digital Diagnostic Monitoring (DDM) provides real-time status of optical parameters to support link validation and ongoing maintenance.

Advantages

This transceiver offers a standardized OSFP form factor for 400G aggregation or spine connections, ensuring compatibility with equipment that accepts OSFP optics. The MPO-MTP-12/APC termination and flat-top ferrule support dense fiber routing and consistent optical performance. Operating at 850 nm on multimode fiber provides a cost-effective short-reach solution for high-bandwidth links, while DDM enables monitoring of temperature, optical power, and other key parameters to aid troubleshooting and operations.

Suitable for

When it may not be suitable

This multimode 850 nm transceiver is intended for short-reach links and is not suitable for long-haul or single-mode fiber networks. It is not appropriate where link distances exceed the specified 50 meters or where single-mode optical interfaces or different wavelengths are required. Also, it requires network equipment with OSFP ports and physical compatibility with MPO-MTP-12/APC terminated multimode cabling.

Key specifications

How to use

Install the OSFP transceiver into a compatible OSFP port on the network switch or router following the equipment vendor's handling and electrostatic discharge guidelines. Connect the MPO-MTP-12/APC multimode fiber cable to the module, ensuring correct alignment and secure connector mating. Verify link status and optical parameters using the host device and the transceiver's DDM readouts. Perform optical loss and polarity checks when integrating into existing patching panels to confirm correct channel mapping and performance.

What to consider before purchase

Recommendations

Use factory-tested multimode MPO-MTP-12/APC patch cords and maintain proper fiber cleanliness. Monitor DDM parameters after installation to detect early signs of connector contamination or fiber loss, and perform periodic verification of connections in high-density racks to sustain link performance.
