## Summary description

The BlueOptics 740-080725-BO is a QSFP28 fiber optic transceiver module designed for high-speed data transmission up to 10000 m. It features an aluminum housing and weighs 40 g, making it lightweight and durable. Ideal for networking applications requiring high bandwidth and long-distance connectivity.

## Long description

The BlueOptics 740-080725-BO QSFP28 transceiver module provides high-speed optical connectivity for long-distance single-mode fiber links up to 10,000 m. Housed in an aluminium casing and weighing approximately 40 g, this QSFP28 module follows industry MSA form factors and uses LC duplex connectors for bidirectional optical transmission. It supports 100G data rates and is designed for integration into network equipment platforms that accept QSFP28 modules.
Advantages
The module delivers 100GBASE-LR4 class performance suitable for long-reach single-mode fiber connections and includes wavelength multiplexing for transmit and receive channels. Its aluminium housing offers mechanical robustness while keeping weight low. Compliance with QSFP28 physical and connector standards ensures interoperability with equipment that supports 100G QSFP28 optical transceivers. The compact QSFP28 format enables high-density port deployment in switches, routers and other data center devices.
Suitable for
Long-distance 100G Ethernet links over single-mode fiber (up to 10 km)
High-capacity interconnects between switches, routers and aggregation equipment
Data center and carrier transport applications requiring QSFP28 modules
Key specifications
Interface type: QSFP28
Data rate: 100 G (100GBASE-LR4 class)
Transmission medium: single-mode fiber
Maximum reach: up to 10,000 m (10 km)
Connector: LC duplex
Housing material: aluminium
Weight: approx. 0.04 kg
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port on your network device until it latches firmly. Connect LC duplex single-mode fiber patch cords to the module's TX and RX ports, observing correct polarity. Ensure the host device supports 100G QSFP28 modules and, if required, enable or verify Digital Diagnostics (DDM/DOM) support in the device software to monitor module parameters. Follow your equipment vendor's hot-swap and handling guidelines to prevent electrostatic damage.
Usage recommendations
For reliable long-distance operation, use single-mode LC patch cords and appropriate fiber routing (avoiding sharp bends). Verify compatibility with your hardware vendor and test links after installation. If your system supports DDM/DOM, monitor real-time parameters such as optical power and temperature to assist with troubleshooting and preventive maintenance.
