BlueOptics PAN-T-Q-40GBASE-LR4-BO network transceiver module QSFP Fiber optic LC

The BlueOptics PAN-T-Q-40GBASE-LR4-BO is a 40GBASE-LR4 QSFP fiber optic transceiver module with an LC duplex connector, designed for long-range single-mode fiber links. Constructed in an aluminium housing and weighing approximately 20 g, this module implements QSFP interface standards and supports high-speed optical transmission up to 40 Gbit/s for data center and enterprise network applications. The module includes CWDM-based transmitter and receiver elements and is intended for environments where reliable long-distance optical connectivity is required.

Advantages

The transceiver follows MSA-compliant QSFP form factor conventions and is engineered to match the electrical and optical behaviour expected in systems that support 40GBASE-LR4 optics. The aluminium housing provides mechanical robustness while keeping the module lightweight. Digital diagnostics (DDM/DOM) support enables real-time monitoring of optical and electrical parameters where host hardware implements the feature. The LR4 CWDM design enables 40 Gbit/s links over single-mode fiber at extended distances suitable for rack-to-rack and inter-building connections.

Suitable for

• 40 Gbit/s Ethernet links over single-mode fiber
• Long-reach connections in data centers and campus networks
• High-speed uplinks between switches, routers and storage systems

How to use

Install the BlueOptics QSFP module into a compatible QSFP port on switches, routers or other network devices while the host system is powered down or following the vendor's hot-swap procedures. Connect LC duplex single-mode fiber patch cords to the module, taking care to match Tx and Rx channels and to use appropriate patch panels or adapters if required. Verify link negotiation and operational status through the host device management interface and, if available, read DDM/DOM values for real-time diagnostics. Follow device vendor guidance for firmware and compatibility checks to ensure correct operation.

Usage recommendations

Use single-mode LC patch cords of suitable type and attenuation for LR4 transmission and ensure cleanliness of fiber connectors before insertion. Confirm that the host hardware supports 40GBASE-LR4 QSFP transceivers and DDM/DOM features for monitoring. For optimal long-distance performance, follow recommended optical power budgets and maintain proper cable routing to avoid excessive bending or stress on fiber runs.
