Product information

Description

The BlueOptics BO25KS856S3D-BO is a 40G optical transceiver module with OSFP interface designed for multimode fiber links at 850 nm. It supports data rates up to 40000 Mbit/s and uses an LC Duplex connection for simultaneous transmit and receive on separate fibers. The module is manufactured to MSA standards and is compatible with hardware platforms that support the original BlueOptics BO25KS856S3D transceiver.

Advantages

This BlueOptics BO25KS856S3D-BO transceiver offers 40G transmission over multimode fiber with a compact OSFP form factor and LC Duplex connector. It includes Digital Diagnostic Monitoring (DDM/DOM) compliant with SFF-8472 for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature. The module is produced using industry-grade components and follows MSA specifications to ensure interoperability and long operating life.

Suitable for

  • 40G Ethernet links in data center switches and routers
  • High-speed interconnects between storage systems and servers
  • Optical uplinks and aggregation links in campus or enterprise networks

Key specifications

  • Manufacturer: BlueOptics
  • Model / MPN: BO25KS856S3D-BO
  • Interface type: OSFP
  • Transmission standard: 40GBASE-SWDM4 (compatible)
  • Wavelength: 850 nm
  • Connector: LC Duplex
  • Maximum data rate: 40000 Mbit/s
  • Medium: Multimode fiber
  • Typical reach: up to 300 m (multimode, depending on cabling and equipment)
  • Weight: 0.04 kg
  • Compliance: MSA; meets common industrial standards (CE, RoHS, FCC as applicable)

How to use

Insert the BlueOptics BO25KS856S3D-BO into a compatible OSFP port on a switch, router or other network device that supports the BlueOptics BO25KS856S3D specification. Connect LC Duplex multimode patch cords between transceivers or to patch panels to establish the optical link. Ensure the host device firmware supports DDM/DOM if you intend to monitor real-time diagnostic parameters. Follow standard electrostatic discharge (ESD) precautions when handling the module and keep the optical connectors clean to maintain signal quality.

Usage recommendations

For optimum performance, use high-quality multimode fiber patch cords and proper patch panel management. Verify device compatibility with the BO25KS856S3D-BO specification and, if possible, test a sample in your environment to confirm interoperability and link budget before large-scale deployment.
