Fiber optic transceiver module BlueOptics 740-066424-BO QSFP 40000 m

The BlueOptics 740-066424-BO QSFP 40000 m is a 40G fiber optic transceiver module designed for single-mode links up to 40,000 meters. Built with an aluminium housing and weighing approximately 40 g, this QSFP transceiver implements the 40GBASE-ER4 optical interface with LC duplex connectivity and uses 1310 nm transmit and receive channels to carry high-speed data over long distances. The module follows MSA-compatible QSFP form-factor conventions and is intended for use in network switches, routers and storage hardware that support 40G optical transceivers.

Advantages

The module offers long-reach single-mode optical transmission capable of carrying up to 40 Gbit/s across distances up to 40 km, while its aluminium enclosure provides a compact and lightweight footprint for dense installations. Designed to meet MSA interoperability, the transceiver is compatible with common 40GBASE-ER4 applications and supports simultaneous send/receive operation over LC duplex fibre. The product is built for stable optical performance and is suitable for installations requiring predictable physical characteristics and straightforward integration.

Suitable for

• Long-distance single-mode fiber backbone links (up to 40 km)
• 40G Ethernet aggregation and core connections
• High-speed connections for routers, switches and storage systems

Key specifications

• Interface type: QSFP (40GBASE-ER4 compatibility)
• Reach: up to 40,000 m (single-mode fiber)
• Wavelength: 1310 nm transmit and receive
• Connector: LC Duplex
• Housing: aluminium
• Weight: 0.04 kg

How to use

Install the QSFP transceiver into a compatible QSFP slot on supported network equipment, ensuring the host device firmware or driver environment supports third-party MSA QSFP modules. Connect LC duplex single-mode fiber patch cords to the module’s transmit and receive ports, observing correct polarity. Power on the host device and verify link status through the device management interface; when supported, enable Digital Diagnostic Monitoring (DDM/DOM) to read real-time parameters such as optical power and temperature for maintenance and troubleshooting.

Recommendations

Use single-mode LC duplex fiber patch cords rated for long-reach transmission and keep connectors clean to maintain signal quality. Verify compatibility with the target hardware platform and ensure that DDM/DOM support is enabled on the host device if remote diagnostics are required. Follow standard electrostatic discharge (ESD) handling procedures when inserting or removing the transceiver.
