QSFP transceiver module BlueOptics 740-067442-BO 40000 Mbit/s

The BlueOptics 740-067442-BO is a QSFP transceiver module designed for high-speed fiber optic connections with a maximum data transfer rate of 40000 Mbit/s. This compact silver module weighs 20 g and provides a standardized QSFP interface for integration into compatible network equipment. The module meets CE, RoHS and FCC requirements and is intended for short-reach multimode fiber links using MPO/MTP connectivity in systems that support 40GBASE-SR4 communication.

Advantages

The transceiver delivers 40 Gbit/s throughput in a small QSFP form factor, enabling high-density port deployment in switches and other network hardware. Its compliance with common regulatory standards ensures compatibility with industry requirements, while the low weight and compact size simplify handling and installation. The design supports MPO/MTP multimode fiber connections and includes the transmitter and receiver functionality needed for parallel optical links.

Suitable for

• Aggregation and spine switches in data center networks
• High-speed uplinks between switches and routers
• Storage area network interconnects and server-to-switch links
• Short-reach multimode fiber connections up to typical 40GBASE-SR4 distances

How to use

Install the QSFP transceiver into a compatible QSFP port on network equipment following the host vendor's hot‑plug and ESD guidelines. Connect MPO/MTP multimode fiber patch cords to the transceiver and ensure correct polarity and fiber type for 40GBASE‑SR4 operation. Verify that the connected hardware supports the required data rate and QSFP transceiver type; enable or check any required port settings in the device firmware. If available, enable Digital Diagnostics Monitoring (DDM/DOM) on the host to monitor optical parameters such as temperature and output power for ongoing link health checks.

Recommendations

When deploying this BlueOptics QSFP module, use high-quality multimode MPO/MTP patch cords and verify compatibility with your switch or router model. Confirm support for 40GBASE-SR4 and DDM/DOM in the host device firmware before production use, and follow proper ESD handling and installation procedures to ensure reliable operation.
