QSFP-transceivermodule BlueOptics QSFP-40G-LR4-20-SW-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-SW-BO is a QSFP-form-factor fiber optic transceiver module engineered for 40 Gbit/s links. Designed for use in high-density network environments such as data centers and aggregation switches, this module supports long-reach single-mode connectivity using LC connectors and delivers a maximum transfer distance of up to 20,000 meters. The compact QSFP interface and low weight make it suitable for modern rack-mounted systems and equipment requiring hot-pluggable 40 GbE or InfiniBand connections.

Advantages

This transceiver provides a standardized QSFP interface for straightforward integration into compatible switch and server ports. With support for 40,000 Mbit/s throughput and single-mode LC connectivity, it enables long-distance data transmission without intermediate repeaters. The module's compact size and 40 g weight reduce space and handling concerns in dense equipment racks, while industry-standard optical parameters ensure predictable link performance and interoperability with other LR4-class transceivers.

Key specifications

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or host adapter following the equipment manufacturer's hot-plugging guidance. Connect single-mode fiber cables with LC connectors to the module's optical ports, ensuring correct polarity. Verify link status and negotiate the expected 40 Gbit/s speed through the network device's management interface. When removing the module, power down or follow hot-swap procedures recommended by the hardware vendor and use dust caps to protect the optical interfaces when idle.

Recommendations

Use single-mode fiber rated for long-reach links and verify end-to-end optical budget compatibility before deployment. Maintain clean LC connectors and handle the transceiver by its housing to avoid contamination. Confirm compatibility with your switch or server vendor's supported transceiver list to ensure full feature support and link stability.
