QSFP Transceiver Module BlueOptics QSFP-LR4-BI-BO Fiber Optic 10km

The BlueOptics QSFP-LR4-BI-BO is a QSFP fiber optic transceiver module designed for 40G optical links over single-mode fiber with a reach of up to 10,000 meters. Constructed in an aluminium housing and weighing approximately 20 grams, this module implements the 40GBASE-LR4 specification with LC duplex connectivity and supports CWDM-based transmit and receive channels. It is intended for data center and enterprise deployments that require long-reach, high-throughput optical connectivity and is compatible with hardware platforms that follow MSA QSFP guidelines.

Advantages

The transceiver provides 40 Gbps aggregated throughput using four CWDM lanes and supports long-distance transmission up to 10 km over single-mode fiber. Its aluminium enclosure offers physical durability while keeping weight low, and the module is built to MSA-compatible form factors to ensure interoperability with compliant switches, routers and storage equipment. Integrated digital diagnostic monitoring (DDM/DOM, SFF-8472 compliant) enables remote measurement of supply voltage, laser bias current, optical transmit/receive power and temperature to assist in maintenance and troubleshooting.

Key specifications

How to use

Insert the QSFP-LR4-BI-BO module into a compatible QSFP port on a switch, router or other optical transceiver host while the device is powered down or according to the host vendor’s hot-plug guidance. Connect LC duplex single-mode fiber patch cables to the module’s LC connector, ensuring correct transmit/receive orientation. Confirm that the host device recognizes the module and that link parameters (40G mode, DDM support) are enabled as required. Use the host management interface or monitoring tools to read DDM values for ongoing diagnostics.

Recommendations

To ensure optimal performance and compliance, use single-mode fiber and quality LC duplex patch cords, verify host platform compatibility with MSA-compliant QSFP-LR4 modules, and enable DDM monitoring if supported by your hardware. Keep connectors clean and follow standard fiber handling practices to maintain signal quality and the rated 10 km reach.
