Fiber optic transceiver module BlueOptics BN-CKM-QP-LR4-BO QSFP 10000 m

The BlueOptics BN-CKM-QP-LR4-BO is a QSFP fiber optic transceiver module designed for high-speed 40G data transmission over single-mode fiber for distances up to 10,000 m. Housed in an aluminium enclosure and weighing approximately 20 g, this module follows MSA form-factor standards and uses an LC duplex interface. It integrates CWDM-based transmitter and receiver stages to support 40GBASE-LR4 optical links and is compatible with major hardware platforms that support the corresponding 40G QSFP specification.

Advantages

The module provides long-reach single-mode performance suitable for 10 km links while maintaining compact QSFP form factor and low weight. Built to MSA standards, it supports multivendor interoperability and includes digital diagnostics (DDM/DOM) functionality for remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature. The aluminium housing offers mechanical robustness and thermal dissipation for stable operation.

How to use

Install the transceiver into an MSA-compliant QSFP slot of a compatible switch, router or storage device, ensuring the host platform officially supports 40GBASE-LR4 QSFP modules. Connect LC duplex single-mode fiber patch cords to the module connectors and confirm proper polarity. Monitor the link status via the host device and, if available, read DDM/DOM parameters through the system management interface to verify power levels and temperature. Follow the host equipment manufacturer’s instructions for safe insertion and removal to avoid damaging the optical interfaces.

Recommendations

Use high-quality single-mode LC duplex patch cords and appropriate patch panels to achieve the specified 10 km reach. Verify host compatibility and firmware settings before deployment, and enable DDM/DOM monitoring where supported to simplify maintenance and fault diagnosis.
