QSFP Transceiver Module BlueOptics QSFP-40G-LR4-LITE-BO Fiber Optic CWDM

The BlueOptics QSFP-40G-LR4-LITE-BO is a 40G QSFP fiber optic transceiver module designed for single-mode CWDM links. It supports 40GBASE-LR4-LITE class transmission over single-mode fiber using an LC duplex connector and complies with MSA form-factor and interface expectations for QSFP modules. The module is lightweight (approximately 40 g) and finished in an aluminium-coloured housing, making it suitable for dense network equipment where space and weight matter.

Advantages

This transceiver implements CWDM optics in a QSFP form factor to enable 40 Gbit/s optical connections on long-reach single-mode fiber. It follows MSA-compatible mechanical and electrical specifications to improve interoperability with major networking platforms that accept QSFP 40G modules. The compact, aluminium-coloured housing and the low weight simplify handling and rack installation. The module is suitable for environments requiring stable optical transmission and reduced electromagnetic interference inherent to fiber links.

How to use

Insert the BlueOptics QSFP-40G-LR4-LITE-BO module into a compatible QSFP slot on your switch, router or other network device following the host vendor's hot-swap and handling guidelines. Connect LC duplex single-mode fiber patch cords to the module's LC ports, ensuring proper polarity and secure mating. Configure the host interface for 40G operation as required by your equipment. If the host supports digital diagnostics, monitor supply voltage, temperature, transmit and receive power and laser bias current via the management interface to verify link health.

Recommendations

Use single-mode LC duplex patch cords of appropriate grade and low-loss connectors, verify polarity and clean connectors before mating. Confirm that the target hardware supports QSFP 40G LR4-LITE modules and DDM/DOM functionality if diagnostics are required. For best results in rack or data center deployments, follow the device vendor's guidelines for hot-plug handling and module compatibility checks.
