QSFP Transceiver Module BlueOptics QSFP-40G-LR4-CT-BO Fiber Optic 10km

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.

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.

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.
