Módulo transceptor QSFP BlueOptics QSFP-40G-LR4-QN-BO fibra LC

The BlueOptics QSFP-40G-LR4-QN-BO is a 40GBASE-LR4 QSFP transceiver module designed for long-range single-mode fiber connections. It uses a QSFP interface with an LC duplex connector and a durable aluminium housing, and it is intended for high-speed applications up to 40 Gbit/s over distances up to 10 km when used with appropriate single-mode fiber. The module supports common protocols such as Ethernet and Fibre Channel over Ethernet and includes CWDM-based transmit and receive channels for wavelength multiplexing.

Advantages

This transceiver is built to MSA standards to ensure interoperability with compatible hardware platforms. It is compact and lightweight, and the aluminium housing provides mechanical protection and heat dissipation. The module includes digital diagnostic monitoring (DDM/DOM) functionality for real-time status of supply voltage, laser bias current, transmit output power, receive input power and temperature. Components are selected to provide extended operational lifetime and high availability in production networks.

Suitable for

• 40 Gbit/s uplinks and aggregation in data centre switches
• High-speed interconnects between storage arrays and switches
• Long-distance single-mode fiber links up to 10 km
• Environments requiring digital diagnostics and remote monitoring

How to use

Install the QSFP transceiver into a compatible QSFP port following the host equipment vendor instructions and observing electrostatic discharge (ESD) precautions. Use appropriate single-mode LC fiber patch cords or pre-terminated links and ensure correct polarity for transmit and receive channels. Verify compatibility with the target switch, router, or storage platform and enable DDM/DOM monitoring if the host supports it. Perform link tests and monitor diagnostic parameters to confirm stable operation.

Recommendations

For reliable long-range performance, use high-quality single-mode fiber and LC duplex patch cords, keep optical connectors clean, and ensure the host device supports QSFP-40G-LR4 modules and DDM/DOM. Observe manufacturer guidance on insertion/removal and ESD handling to preserve module lifespan.
