## Long description

The BlueOptics QSFP-40GE-LR4-AR-BO is a 40G fiber optic transceiver module designed for long-range single-mode links. It uses a QSFP interface with LC duplex connectors and supports 40GBASE-LR4 optical transmission. The module is lightweight (0.02 kg) and finished in aluminium colour, making it suitable for installation in compatible QSFP ports in switches, routers and other networking equipment that accept 40GBASE-LR4 QSFP modules.
Advantages
This transceiver follows MSA-compliant QSFP mechanical and electrical specifications to ensure interoperability with major network hardware. It provides long-distance single-mode transmission with CWDM-based transmit and receive channels, enabling 40 Gbit/s links over extended ranges. The module includes digital diagnostics monitoring (DDM/DOM) support for real-time reporting of supply voltage, laser bias current, transmit power, receive power and temperature when used in hardware that supports these functions. The compact, lightweight design facilitates handling and installation in dense data center environments.
Suitable for
40G backbone links in data centers and enterprise networks
Long-reach single-mode fiber connections (40GBASE-LR4)
Interconnects between switches, routers and storage systems supporting QSFP

How to use
Insert the QSFP-40GE-LR4-AR-BO module into a compatible QSFP port until it latches according to the host device instructions. Connect LC duplex single-mode patch cords to the module’s LC receptacles, observing correct transmit/receive orientation. Ensure the host device is configured for 40GBASE-LR4 operation and, if needed, enable DDM/DOM support in the management interface to monitor module parameters. Follow standard electrostatic discharge (ESD) precautions during handling and avoid contaminating fiber endfaces; clean connectors before making the final connection.
Usage recommendations
Use single-mode LC duplex fiber cabling rated for long-reach 40G links and compatible patch panels or adaptors. Verify compatibility with the specific network hardware and firmware version before deployment and perform link testing after installation. Keep spare modules and clean connector tools available for maintenance to maintain high availability of optical links.
