## Summary description

SFP28 optical transceiver BlueOptics BYBJ-BO supports 10G and 25GBASE-SR operation over multimode fiber with an 850 nm wavelength and LC-duplex connector. Designed for short-reach links up to 100 meters, it includes DDM for diagnostics and operates in the 0–70°C range. Suitable for data center uplinks, switch-to-switch connections and high-speed aggregation.

## Long description

The SFP28 Transceiver BlueOptics BYBJ-BO 10G/25GBASE-SR is an optical module designed for short-reach multimode fiber links. It supports both 10G and 25GBASE-SR operation using an 850 nm wavelength and LC-duplex connector, providing compatibility with common data center and enterprise networking equipment. The module supports reaches up to 100 meters over suitable multimode fiber and includes Digital Diagnostic Monitoring (DDM) for real-time status of optical parameters. The operating temperature range is 0–70°C, making it suitable for standard indoor rack and cabinet environments.
Advantages
This transceiver offers dual-rate support for 10G and 25G networks in a compact SFP28 form factor, enabling flexible deployment in mixed-rate environments. The LC-duplex interface and multimode 850 nm optics are widely compatible with existing fiber infrastructure for short-reach connections. Integrated DDM provides monitoring of optical power, temperature and other diagnostic metrics to assist with link troubleshooting and maintenance. The specified operating temperature range and industry-standard mechanical dimensions ensure predictable behavior in typical data center and telecom closets.
Suitable for
 Data center server and switch uplinks
 Switch-to-switch aggregation links within racks and rows
 High-speed interconnects in enterprise LANs
 Short-reach fiber backbones and patch-panel connections up to 100 m
Key specifications
 Supported standards: 10GBASE-SR and 25GBASE-SR
 Form factor: SFP28
 Wavelength: 850 nm
 Connector type: LC duplex
 Maximum reach: up to 100 meters over multimode fiber
 Diagnostics: Digital Diagnostic Monitoring (DDM)
 Operating temperature: 0–70°C
How to use
Install the SFP28 transceiver into a compatible SFP28-capable port following the host equipment manufacturer's instructions. Ensure the LC-duplex multimode patch cable is clean and properly seated to avoid signal loss. Verify link status and speed negotiation via the switch or server management interface; the module can operate at 10G or 25G depending on the connected devices. Use the DDM functions through the host to monitor transmit/receive power, temperature and other diagnostics to confirm link health.
Usage recommendations
For reliable performance, pair the transceiver with OM3/OM4 multimode fiber for links approaching the 100 m limit and maintain clean fiber endfaces. Monitor DDM values after installation to detect connector contamination or fiber bend loss early. Avoid exposing the module to temperatures outside the 0–70°C range and ensure proper airflow in densely populated racks.
