SFP28-transceiver BlueOptics BYBJ-BO 10G/25GBASE-SR, LC-duplex, multimode 850nm, 100m, DDM, 0–70°C

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.

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.

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.
