BlueOptics QSFP28 Transceiver S2P29A-BO, 100GBASE-FR, LC-Duplex, Singlemode, 1310nm, PAM4, 2 km, DDM

The BlueOptics QSFP28 Transceiver S2P29A-BO is a 100GBASE-FR optical module designed for short-reach, high-speed singlemode fiber links. With an LC-duplex interface and operation at 1310 nm using PAM4 modulation, this QSFP28 transceiver supports 100 Gb/s FR connections and includes digital diagnostic monitoring (DDM) for real-time status reporting. It is specified for a reach of up to 2 km and an operating temperature range of 0°C to +70°C, making it suitable for data center interconnects and carrier transport segments that require reliable 100G FR connectivity.

Advantages

The module provides 100 Gb/s capacity over singlemode fiber using PAM4 encoding, enabling higher spectral efficiency compared with NRZ-based alternatives. Its LC-duplex connector is compatible with common singlemode patching infrastructure, and integrated DDM gives continuous monitoring of optical parameters such as transmit and receive power, temperature and laser bias. The QSFP28 form factor supports compact installation in switch and router ports, while the specified 2 km reach covers typical campus, data center and metro interconnect distances within operator networks.

Suitable for

• 100GBASE-FR links between switches or routers over singlemode fiber
• Data center interconnects and spine-leaf aggregation requiring 100 Gb/s links
• Carrier or metro transport segments up to 2 km
• Environments needing optical monitoring via DDM

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or media converter following the host device manufacturer’s hot-plug guidance. Connect LC-duplex singlemode patch cords to the transmit and receive ports, taking care with fiber polarity. Verify the link status on the host device and monitor optical parameters via the DDM interface to confirm power levels and temperature are within expected ranges. Ensure the host platform is configured for 100GBASE-FR operation and that PHY settings match the module’s PAM4 signaling.

Usage recommendations

Use singlemode LC-duplex patch cords rated for 1310 nm and maintain clean connector endfaces to avoid signal loss. When deploying in data center or carrier environments, validate compatibility with the host equipment and perform link verification after installation. Monitor DDM readings periodically to detect degradation in optical power or temperature anomalies.
