## Summary description

The BlueOptics QSFP-40G-LR4-CT-BO is a fiber optic transceiver module designed for high-speed data transmission over distances up to 10,000 meters. It features a QSFP interface and is lightweight at only 20 grams, making it ideal for network applications requiring efficient and reliable connectivity. The aluminum construction ensures durability and performance in various environments.

## Long description

The BlueOptics QSFP-40G-LR4-CT-BO is a 40G QSFP fiber optic transceiver module designed for single-mode optical links up to 10 km. It implements a QSFP interface in a compact, lightweight aluminum housing (approx. 20 g) and is intended for high-speed network connections that require standardized 40GBASE-LR4 optics with LC duplex connectivity and single-mode fiber.
Advantages
This transceiver offers long-reach single-mode transmission complying with 40GBASE-LR4 optical use cases while remaining compact and lightweight. The aluminium construction provides mechanical durability and effective heat dissipation. The QSFP form factor enables high port density and hot-pluggable replacement in compatible network equipment. Digital diagnostic monitoring (DDM/DOM) support simplifies remote performance monitoring when the host hardware supports the feature.
Suitable for
 40 Gigabit Ethernet links over single-mode fiber up to 10 km
 High-density switch and router uplinks requiring QSFP modules
 Interconnects between data center equipment such as switches, routers and storage systems
 Long-distance optical connections in campus and metro networks
Key specifications
 Interface type: QSFP
 Optical standard: 40GBASE-LR4 (single-mode fiber)
 Maximum reach: up to 10,000 meters (10 km) over single-mode fiber
 Connector type: LC duplex
 Housing material: aluminium
 Weight: approximately 0.02 kg
 Form factor: QSFP (hot-pluggable)
How to use
Insert the QSFP-40G-LR4-CT-BO module into a compatible QSFP port on supported switches, routers or other network devices while the host device is powered according to the vendor’s guidance for hot-pluggable modules. Connect LC duplex single-mode fiber patch cords to the module’s LC receptacles, ensuring correct transmit/receive orientation. Verify link status and, if available, read DDM/DOM parameters from the host system to monitor optical power, temperature and supply voltage. Follow the equipment manufacturer’s instructions for firmware or software settings required for 40GBASE-LR4 operation.
Usage recommendations
Ensure the target hardware officially supports third-party QSFP-40G-LR4 modules and that the host device firmware permits third-party optics. Use quality single-mode LC duplex patch cords and maintain clean connectors to achieve optimal optical performance. For remote diagnostics, confirm the host supports DDM/DOM to access real-time module parameters.
