Fiber optic transceiver module BlueOptics 740-073096-BO QSFP LC Aluminium

The BlueOptics 740-073096-BO QSFP LC Aluminium is a fiber optic transceiver module designed for 40G high-speed optical links. Built with an aluminium housing and an LC duplex interface, this QSFP module follows MSA-compliant form factor and is intended for single-mode fiber transmission. The module is lightweight (approximately 20 g) and supports long-reach optical communication up to distances typical for LR4 class 40G modules, enabling integration into switches, routers and other networking equipment that accept QSFP LR4 transceivers.

Advantages

This QSFP transceiver offers a compact aluminium housing for robust mechanical protection and reduced weight, an industry-standard LC connector for duplex single-mode fiber connections, and compatibility with systems that support 40GBASE-LR4 QSFP modules. The design includes CWDM-based transmit and receive channels for multi-wavelength LR4 operation and is produced to meet MSA form-factor and interface expectations for reliable interoperability.

Suitable for

• 40G Ethernet links between data center switches and aggregation equipment
• High-speed connections in carrier and metro networks requiring LR4 single-mode links
• Interconnection of routers, storage systems and load balancers supporting QSFP 40G modules

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Connector: LC duplex
• Transmission class: 40GBASE-LR4 (CWDM-based 4-channel LR transmission)
• Fiber type: Single-mode fiber
• Housing material: Aluminium
• Weight: approximately 0.02 kg

How to use

Insert the QSFP module into a compatible QSFP port on the network device while the device is powered according to the vendor’s hot-plug guidelines. Connect LC duplex single-mode fiber patch cords to the module’s LC connector, ensuring correct transmit/receive orientation. Allow the host device to recognize the transceiver and negotiate link parameters; verify link status and optical levels through device management or supported digital diagnostic functions if available. Follow the network equipment manufacturer’s instructions for firmware and compatibility requirements.

Recommendations

Use high-quality single-mode LC patch cords and, where possible, route fibers through protective panels or trunking to maintain optical performance. Confirm that the target host supports 40GBASE-LR4 QSFP modules and, if system-level diagnostics are required, ensure the host supports Digital Diagnostics Monitoring (DDM/DOM) to access real-time parameters such as supply voltage, laser bias, output and received power, and temperature.
