QSFP Transceiver BlueOptics QSFP-IR4-BI-BO 40000 Mbit/s Silver

The BlueOptics QSFP-IR4-BI-BO is a QSFP fiber-optic transceiver module designed for high-speed optical links up to 40000 Mbit/s. It uses LC duplex connectors and single-mode fiber to support long-reach transmission up to 2,000 m. Housed in a compact, silver enclosure and weighing approximately 40 g, this module follows MSA QSFP form-factor conventions and supports common protocols such as Ethernet and Fibre Channel over Ethernet for 40 Gbit/s links. It includes CWDM transmitter and receiver channels and offers Digital Diagnostics Monitoring (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, TX output power, RX input power and temperature, where supported by the host hardware.

Advantages

The module provides 40 Gbit/s data throughput over single-mode fiber with an optical reach suitable for campus and data center interconnects up to 2 km. Compatibility with MSA-compliant QSFP ports and LC duplex cabling simplifies integration into switches, routers and storage systems. Built-in digital diagnostics enable remote monitoring and facilitate fault finding and preventive maintenance. The compact QSFP form factor and low weight make installation and replacement straightforward.

How to use

Install the QSFP transceiver into an MSA-compliant QSFP port of a switch, router or other network appliance that supports 40 Gbit/s QSFP modules. Connect LC duplex single-mode fiber patch cords to the transceiver’s LC connector, observing proper polarity. Verify that the host device recognizes the module and, if required, enable or confirm DDM/DOM support in the device management interface to access diagnostic values. For optimal performance, use single-mode fiber rated for the intended distance and follow the equipment vendor’s cable routing and bend-radius guidelines.

Recommendations

Ensure host compatibility with QSFP LR4L/CWDM modules before installation and use high-quality single-mode LC duplex patch cords and, where possible, patch panels to preserve signal quality. If remote monitoring is required, confirm that the host hardware supports DDM/DOM to access real-time diagnostic data. Handle the optical interfaces with dust caps in place until connection and avoid touching fiber endfaces to reduce connector contamination.
