QSFP-transceivermodule BlueOptics QSFP-40G-LR4-IA-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-IA-BO is a QSFP optical transceiver module designed for fiber-optic network links with a maximum data rate of 40 Mbit/s. The module uses a QSFP interface in a metal housing, weighs 20 g and is specified with an MTBF of 1,000,000 hours, offering a compact and durable option for single-mode fiber connections with LC Duplex termination. The transceiver implements the 40GBASE-LR4 transmission profile and supports digital diagnostics for monitoring key operating parameters.

Advantages

The module's metal housing provides mechanical durability and thermal stability while its small, lightweight form factor simplifies installation and handling in switches, routers and other network equipment. High MTBF indicates long operational life and reduced maintenance intervals. Compliance with QSFP MSA electrical and mechanical conventions promotes interoperability with systems that support 40GBASE-LR4 QSFP modules. Integrated digital diagnostics enable remote monitoring of supply voltage, laser bias current, optical power and temperature where supported by host hardware.

Suitable for

• 40G optical uplinks between switches and routers over single-mode fiber
• High-speed data center interconnects up to the supported link distance of the LR4 profile
• Storage area network and Fibre Channel over Ethernet links requiring QSFP form factor
• Equipment that supports QSFP 40GBASE-LR4 transceivers with LC Duplex interfaces

How to use

Install the BlueOptics QSFP-40G-LR4-IA-BO by inserting it into a compatible QSFP slot on the host device following the manufacturer's hot-plug procedures. Connect LC Duplex single-mode fiber patch cords to the transceiver's ports, taking care to match transmit and receive channels. Ensure that the host equipment firmware and software support 40GBASE-LR4 QSFP modules and, if required, enable DDM/DOM monitoring in the management interface to read real-time diagnostics. Follow standard ESD precautions and handle the transceiver by its edges to avoid contaminating optical interfaces.

Recommendations

Use high-quality single-mode LC Duplex fiber patch cords and clean connector end-faces before mating. Verify host compatibility with 40GBASE-LR4 QSFP modules and confirm support for digital diagnostics if monitoring is needed. Store unused transceivers in protective packaging and avoid exposing them to dust or moisture. For long links, follow the LR4 profile distance guidelines and perform link verification after installation.
