Fiber optic transceiver module BlueOptics QSFPP-40GBASE-ER4-BO QSFP 40000 m

The BlueOptics QSFPP-40GBASE-ER4-BO is a QSFP fiber optic transceiver module designed for long-distance 40G optical links. It supports 40GBASE-ER4 transmission over single-mode fiber with LC Duplex connectors, comes in an aluminium housing and weighs approximately 40 g. The module implements separate 1310 nm transmit and receive channels and is built to meet MSA form-factor and interoperability expectations for use in compatible network switches, routers and other 40G-capable equipment.

Advantages

This BlueOptics QSFP module provides long-reach data transmission capability up to 40 km over single-mode fiber while maintaining a compact, lightweight aluminium enclosure. The product follows established MSA mechanical and electrical standards and is designed for compatibility with major vendor hardware that supports equivalent 40GBASE-ER4 QSFP modules. Built with industry-grade optical and electronic components, it offers diagnostic access via standard digital monitoring interfaces for real-time signal and device parameters.

Key specifications

How to use

Install the transceiver into an appropriate QSFP port on supported networking hardware while the system is powered down or following the device vendor’s hot-swap guidance. Connect LC Duplex single-mode fiber patch cords to the module’s transmit and receive ports, ensuring correct polarity. Confirm link parameters and module recognition in the host device management interface; enable or verify digital diagnostics if monitoring of supply voltage, laser bias current, output/input power and temperature is required. Follow the switch or router vendor documentation for any required firmware or compatibility settings.

Recommendations

Use single-mode LC Duplex fiber patch cords and, where possible, manufacturer-recommended patch panels or adapters to achieve optimal optical performance. Verify DDM/DOM support in the host hardware to enable real-time diagnostics. Handle the module by the housing, protect the optical interfaces with dust caps when not connected, and observe electrostatic discharge (ESD) precautions during installation and removal.
