QSFP28 transceiver BlueOptics SPTSBP4LLCDF-BO 100000 Mbit/s

The BlueOptics SPTSBP4LLCDF-BO is a QSFP28 fiber optic transceiver module designed for 100GBASE-LR4 applications. It supports a maximum data transfer rate of 100000 Mbit/s over single-mode fiber and uses an LC duplex connector. The module follows MSA QSFP28 form-factor specifications, has a silver housing, and a compact weight of 40 g. It includes CWDM-based transmitter and receiver sections and offers Digital Diagnostics Monitoring (DDM/DOM) capabilities for real-time parameter monitoring.

Advantages

This QSFP28 transceiver provides reliable high-speed optical transmission up to 100 Gbit/s with support for Ethernet and related protocols. It is built to MSA standards to ensure mechanical and electrical compatibility with QSFP28 ports that support 100GBASE-LR4. Integrated digital diagnostics enable remote monitoring of supply voltage, laser bias current, optical output and input power, and temperature. The module’s single-mode LC duplex interface and CWDM design enable long-reach links while minimizing electromagnetic interference.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port according to the host device manual, ensuring the module is fully seated and latched. Connect single-mode LC duplex fiber patch cords to the module’s LC ports, observing correct TX/RX orientation. Verify that the host hardware and firmware support 100GBASE-LR4 optics and that DDM/DOM functions are enabled if remote diagnostics are required. After installation, monitor link status and diagnostic parameters via the switch or transceiver management interface.

Recommendations

Use high-quality single-mode LC duplex patch cords and, where applicable, route fibers via a patch panel to maintain optimal link performance. Confirm host compatibility with QSFP28 LR4 modules before deployment and keep firmware up to date to ensure proper recognition and diagnostic access.
