QSFP transceiver module BlueOptics 740-067443-BO 40000 Mbit/s

The BlueOptics 740-067443-BO is a QSFP fiber optic transceiver module designed for high-speed network links with a maximum data transfer rate of 40000 Mbit/s. The module uses a QSFP interface and an MPO/MTP connector in accordance with MSA standards, supports multimode fiber connections with 850 nm transmitter and receiver wavelengths, and is intended for short-range 40GBASE-SR4 applications. It is finished in silver, weighs approximately 20 g, and meets CE, RoHS and FCC compliance requirements.

Advantages

This QSFP transceiver delivers 40 Gbit/s aggregated throughput in a compact form factor compatible with standard QSFP ports. Built and tested to MSA guidelines, the module supports digital diagnostics for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature where the host system supports DDM/DOM. The product’s use of established optical components and a manufacturing focus on compatibility aims to provide reliable operation and a long service life.

Suitable for

• 40G Ethernet links in data center top-of-rack and spine switches
• High-speed interconnects between routers, switches and storage systems
• Fibre Channel over Ethernet and SDH/SONET applications up to 40 Gbit/s
• Short-range multimode fiber connections up to the supported distance for SR4

• Weight: approx. 0.02 kg

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or storage device that supports 40GBASE-SR4 modules and hot‑plug insertion. Connect a compatible MPO/MTP multimode fiber patch cord to the transceiver and verify link status via the host device. If the host supports digital diagnostics, read the DDM/DOM values through the management interface to monitor optical parameters and temperature. Follow the equipment vendor’s guidance for safe hot‑plugging and handling to avoid electrostatic or mechanical damage.

Recommendations

Use multimode fiber and MPO/MTP patch cords rated for 40GBASE-SR4 distances, ensure the host hardware firmware supports third‑party QSFP modules and DDM/DOM if needed, and keep connectors and fibers clean to maintain signal quality and link reliability.
