## Summary description

Compact BlueOptics OSFP twin-port transceiver P49762-B21-BO provides two 400GBASE-SR4 channels over multimode fiber with MPO/MTP-12 APC connectors. Operates at 850 nm for up to 50 m on suitable MMF and supports digital diagnostic monitoring (DDM). Designed for high-density 400 Gbps links in data centers and aggregation switches, operating between 0°C and +70°C.

## Long description

The BlueOptics OSFP Twin-Port Transceiver P49762-B21-BO is a compact, high-density optical module designed to provide two independent 400GBASE-SR4 channels over multimode fiber. It uses MPO/MTP-12 APC connectors and operates at 850 nm, supporting link distances up to 50 meters on appropriate OM3/OM4 multimode fiber. The module supports digital diagnostic monitoring (DDM) and is specified for operation in standard data center ambient temperatures from 0°C to +70°C, making it suitable for aggregation switches and spine-leaf fabrics that require dual 400 Gbps ports in an OSFP form factor.
Advantages
The transceiver delivers two 400 Gbps channels in a single OSFP package, enabling high port density and reduced rack space for top-of-rack or spine deployments. MPO/MTP-12 APC connectors facilitate orderly fiber management for multimode ribbon cables, and the 850 nm wavelength is standard for short-reach multimode links. Built-in DDM provides real-time monitoring of optical parameters to aid diagnostics and maintenance. The specified operating temperature range supports typical enterprise and data center environments.
Suitable for
Short-reach 400G aggregation links inside data centers (up to 50 m on suitable MMF)
High-density switch ports where two 400G channels in one OSFP module are needed
Spine-leaf and top-of-rack fabrics using multimode fiber and MPO/MTP cabling
Environments requiring real-time optical monitoring via DDM
When it may not be suitable
This module is intended for multimode short-reach links and is not suitable for single-mode long-haul connections or runs that exceed the specified 50 m reach on multimode fiber. It also requires switch hardware that accepts OSFP form-factor modules and supports twin-port 400GBASE-SR4 optics; it will not be compatible with devices that only accept QSFP-DD, CFP, or proprietary module types.
Key specifications
Form factor: OSFP twin-port (dual 400G channels)
Ethernet standard: 2 × 400GBASE-SR4
Wavelength: 850 nm
Fiber type: Multimode fiber (MMF), recommended OM3/OM4
Maximum reach: up to 50 meters on appropriate MMF
Connectors: MPO/MTP-12 APC
Monitoring: Digital Diagnostic Monitoring (DDM)
Operating temperature: 0°C to +70°C
How to use
Install the BlueOptics OSFP transceiver into a compatible OSFP slot following the host equipment vendor’s insertion and removal procedures. Use MPO/MTP-12 APC multimode ribbon cables and ensure correct polarity and cable type (OM3/OM4) to achieve the specified reach. Verify that the switch or router firmware supports twin-port 400GBASE-SR4 operation and enable optical monitoring if required. Monitor DDM outputs for optical power, temperature, and other parameters to assist with link qualification and troubleshooting.
What to consider before purchase
Ensure your switch or router accepts OSFP form-factor modules and supports dual 400GBASE-SR4 ports
Confirm the installed multimode fiber type (OM3/OM4) and link distance to match the 50 m maximum reach
Check connector compatibility with your MPO/MTP-12 APC cabling and patch panels
Verify that your management systems can read DDM parameters if optical monitoring is required
Usage recommendations
Use certified OM3 or OM4 multimode fiber and factory-tested MPO/MTP-12 APC assemblies for reliable short-reach 400G links. Keep fiber runs within the 50 m limit, maintain proper connector cleanliness, and monitor DDM values during initial bring-up and periodic maintenance to ensure stable performance.
