## Summary description

The BlueOptics DEM-Q2810Q-LR4-BO is a fiber optic QSFP28 transceiver module designed for high-speed data transmission. It features an LC connector and is lightweight at 40g, making it ideal for various networking applications. The module is suitable for long-range communication, ensuring reliable performance.

## Long description

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.
Suitable for
 100 Gbit/s Ethernet links over single-mode fiber
 Data center interconnects and aggregation links
 High-speed links between switches, routers and storage systems
 Long-reach metropolitan connections up to several kilometers
Key specifications
 Interface type: QSFP28 form factor with LC duplex connector
 Supported data rate: 100 Gbit/s (100GBASE-LR4 class)
 Fiber type: single-mode fiber (SMF)
 Optical signalling: CWDM-based Tx/Rx channels for LR4 operation
 Housing colour: aluminium
 Weight: 0.04 kg
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.
Usage 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.
