QSFP transceiver module BlueOptics 720190-B21-BO 40000 Mbit/s

The BlueOptics 720190-B21-BO QSFP transceiver module is engineered for high-speed optical connectivity in data center and enterprise networks. Supporting a maximum data transfer rate of 40000 Mbit/s over fiber, this compact silver module provides a lightweight solution for 40 Gigabit Ethernet links. With an LC fiber connector and a rated maximum transfer distance of 10000 m, it is designed to support long-range links where low latency and dependable throughput are required. The module's mean time between failures (MTBF) of 1,000,000 hours indicates a design focused on continuous operation and reliability.

Advantages

The transceiver supports native 40 Gigabit Ethernet speeds and uses standard LC connectors for broad compatibility with duplex fiber cabling. Its compact QSFP form factor and 20 g weight make it suitable for high-density switch and router ports, while the silver housing aids thermal dissipation. The long maximum transfer distance enables connections across floors or between buildings without intermediate conversion, and the high MTBF reduces the need for frequent replacements.

Suitable for

• 40 Gigabit Ethernet uplinks in data centers and aggregation switches
• Long-distance fiber links up to 10 km between network devices
• High-density switch port upgrades where QSFP form factor is required
• Enterprise backbone connections and campus network interconnects

How to use

Install the QSFP transceiver into a compatible QSFP slot on your switch or router following the device manufacturer's insertion procedure. Connect duplex LC fiber patch cables to the module's LC ports, ensuring correct transmit/receive orientation. Verify link status through the host device management interface and configure the corresponding interface for 40 Gigabit Ethernet operation. Observe ESD precautions when handling the module and keep protective dust caps on unused connectors until cabling is complete.

Recommendations

For reliable long-term operation, use single-mode fiber certified for the intended distance, maintain clean LC connector endfaces, and monitor link status and temperature on the host device. Replace the module only with compatible QSFP transceivers to preserve link integrity and interoperability.
