Módulo transceptor QSFP BlueOptics QSFP-40G-LR4-QL-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-QL-BO is a QSFP fiber optic transceiver module engineered for high-speed single-mode fiber links with a maximum data transfer rate of 40 Mbit/s. Encased in a metal housing and weighing approximately 20 g, the module operates from a 3.3 V supply and is built for continuous operation with a specified MTBF of 1,000,000 hours. The module uses LC duplex connections and follows MSA-compliant QSFP form-factor conventions for compatibility with network equipment that supports QSFP transceivers.

Advantages

The module provides stable optical transmission over single-mode fiber using CWDM-based transmitter and receiver elements and supports standard QSFP electrical, mechanical and functional interfaces. Its compact metal enclosure and low weight make installation straightforward while the high MTBF indicates a design focused on long operational lifetime. Digital diagnostics (DDM/DOM) functionality enables real-time monitoring of operating parameters where supported by host hardware.

Suitable for (use cases)

• 40G links between switches and routers over single-mode fiber
• High-speed connections in data centers and campus networks
• Interconnects for storage systems and network appliances that accept QSFP modules
• Long-reach optical links up to several kilometers when used with appropriate single-mode fiber and patching

Key specifications

• Interface type: QSFP
• Maximum data transfer rate: 40 Mbit/s
• Connector: LC duplex (optical)
• Fiber type: single-mode fiber (SMF)
• Operating voltage: 3.3 V
• Housing: metal enclosure
• Weight: 0.02 kg

How to use

Install the QSFP module into a compatible QSFP port on a switch, router or other network device following the host manufacturer's insertion/removal procedure. Use LC duplex single-mode patch cords to connect the transceiver to the remote optical device or patch panel, ensuring correct transmit/receive orientation. Verify that the host device supports the QSFP form factor and that DDM/DOM monitoring is enabled in the host software if you intend to monitor optical parameters. Power is supplied through the host chassis at 3.3 V; no external power connection is required to the module itself.

Recommendations

For reliable performance, pair the transceiver with single-mode LC duplex fiber cables and maintain clean connector endfaces. Confirm compatibility with the target hardware platform and enable digital diagnostics in the host system to monitor voltage, temperature and optical power. Follow ESD precautions during handling and adhere to the host vendor’s guidelines for hot-plugging and firmware compatibility.
