## Long description

The BlueOptics 740-074685-BO QSFP28 LC is a fiber optic transceiver module designed for 100G high-speed optical links. It implements the QSFP28 interface with an LC duplex connector and is housed in an aluminium case. The module is intended for single‑mode fiber deployments where stable, long‑reach transmission and standard MSA mechanical compatibility are required. It is compact and lightweight (approx. 0.04 kg) for easy handling and installation in compatible network equipment.
Advantages
This transceiver provides standardized QSFP28 connectivity with an LC connector for single‑mode fiber, enabling support for 100G optical protocols. The aluminium housing offers mechanical robustness and thermal conduction for reliable operation in rack and system environments. The module is engineered to comply with MSA specifications and to function with hardware platforms that support the corresponding 100GBASE‑LR4 QSFP28 interfaces.
Suitable for
100G Ethernet links over single‑mode fiber
High‑capacity switch-to-switch or router‑to-router uplinks
Data center interconnects and aggregation links
Storage networking and SAN uplinks supporting 100G
Key specifications
Interface type: QSFP28
Connector: LC duplex (single‑mode fiber)
Form factor: QSFP28 optical transceiver
Housing material: aluminium
Weight: 0.04 kg
Intended data rate: 100 G (100GBASE‑LR4 class links)
How to use
Install the BlueOptics QSFP28 transceiver into a compatible QSFP28 slot on switches, routers or other network devices while the host device is powered according to the vendor’s installation instructions. Connect an LC duplex single‑mode fiber patch cord to the transceiver’s LC connector, ensuring correct transmit/receive orientation. Confirm link status and module recognition via the host device management interface. If supported by the host, monitor the transceiver using the module’s digital diagnostic functions to check optical power, temperature and supply parameters.
Usage recommendations
Use single‑mode LC duplex patch cords and maintain clean fiber endfaces for optimal performance. Verify host compatibility with 100GBASE‑LR4 QSFP28 modules and confirm that the device firmware supports third‑party transceivers. Use digital diagnostic monitoring where available to simplify maintenance and troubleshooting.
