Fiber optic transceiver module BlueOptics DEM-Q2810Q-LR4-BO QSFP28 LC

The BlueOptics DEM-Q2810Q-LR4-BO QSFP28 LC fiber optic transceiver module is a compact, lightweight 100GBASE-LR4 solution for long-range single-mode fiber links. Designed to the MSA QSFP28 form factor, this module uses an LC duplex interface and supports high-speed optical transmission over distances suitable for metro and data center interconnects. With an aluminium-coloured housing and a weight of approximately 0.04 kg, the module is intended for use in networking equipment that accepts QSFP28 optics.

Advantages

The module follows MSA-compliant QSFP28 design and provides a standardized LC duplex physical interface for compatibility with a wide range of switches, routers and optical equipment. It supports long-range single-mode fiber transmission with CWDM-based Tx and Rx channels, enabling 100 Gbit/s aggregate throughput while minimizing electromagnetic interference inherent to copper links. The lightweight aluminium housing simplifies handling and installation in dense rack environments.

How to use

Install the BlueOptics QSFP28 module into a compatible QSFP28 slot on a switch, router or optical device, taking care to align the module correctly and engage any retention mechanism. Connect LC duplex single-mode patch cords to the module’s LC ports, observing correct Tx/Rx orientation. Ensure the host device supports 100GBASE-LR4 QSFP28 modules and, if required, enable digital diagnostics (DDM/DOM) support in the host management interface to monitor operational parameters. Perform link validation and optical power checks after installation to confirm proper operation.

Recommendations

Use high-quality single-mode LC patch cords and, where possible, connect through appropriate patch panels to preserve transmit/receive alignment and minimize insertion loss. Verify host compatibility with QSFP28 LR4 optics and enable DDM/DOM monitoring if available to track voltage, temperature, laser bias and optical power for easier maintenance.
