BlueOptics QSFP28-transceiver S3N88A-BO — 100GBASE-DR, LC-duplex, singlemode 1310nm, PAM4, 500m, DDM/DOM

BlueOptics QSFP28 Transceiver S3N88A-BO delivers 100GBASE-DR optical connectivity over singlemode fiber using LC-duplex connectors. It operates at 1310 nm with PAM4 modulation and supports link distances up to 500 meters. The module supports DDM/DOM diagnostic monitoring and is specified for operation between 0°C and +70°C, making it suitable for data center uplinks and enterprise backbone links where 100 Gbit/s singlemode connections are required.

Advantages

The transceiver implements the QSFP28 form factor and conforms to MSA-based interface standards to ensure interoperability with common hardware platforms that accept 100GBASE-DR QSFP28 modules. PAM4 modulation and singlemode operation at 1310 nm enable 100 Gbit/s transmission up to 500 m over singlemode fiber. Built-in digital diagnostics (DDM/DOM) provides real-time monitoring of parameters such as optical power, temperature and supply voltage for simplified maintenance and troubleshooting. The compact, silver-colored module is lightweight and designed for continuous operation in typical data center temperature ranges.

How to use

Install the QSFP28 transceiver into a supported QSFP28 slot on a switch, router or other networking device while following the host vendor's hot-plug and electrostatic discharge precautions. Connect LC-duplex singlemode patch cables to the transceiver's LC ports ensuring correct transmit/receive orientation. After insertion, verify link status and negotiated speed on the host device. Use the host or management software to read DDM/DOM parameters if supported by the platform to confirm optical power levels and operating temperature.

Recommendations

Use high-quality singlemode LC patch cables and, where possible, test optical power and end-to-end loss before deployment. Ensure the hosting device firmware supports third-party QSFP28 modules and enables DDM/DOM access. Keep operating temperature within the specified range and avoid bending or stressing fiber around the transceiver to maintain signal quality and module lifetime.
