QSFP Transceiver Module BlueOptics QSFP-40G-LR4-20-BR-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-BR-BO is a QSFP transceiver module engineered for 40 Gbit/s optical links. Designed for use in high-density network environments, this module supports long-range single-mode fiber connections with LC connectors and a maximum reach of 20,000 m. With a compact form factor and a weight of 40 g, it integrates into switches, routers and media converters that accept QSFP interfaces to deliver stable high-speed connectivity in data centers and enterprise networks.

Advantages

The transceiver provides a standardized QSFP interface for easy hot-plug installation and interoperability with compatible network equipment. It supports 40 Gbit/s aggregated bandwidth over LR4 wavelength division multiplexing, enabling long-reach single-mode links while maintaining low physical footprint and energy-efficient operation. Its LC fiber connectivity and 20 km maximum distance make it suitable for campus, metro and inter-site links where single-mode fiber is available.

How to use

Install the QSFP module into a compatible QSFP port on network equipment while the device is powered according to the vendor's guidance for hot-plug transceivers. Connect single-mode LC fiber patch cords to the module's LC ports, ensuring correct polarity and secure connections. Confirm link status and port configuration on the switch or router management interface; configure speed and mode if required by the host device. Follow equipment-specific procedures for transceiver diagnostics and firmware compatibility.

Recommendations

Use single-mode fiber with appropriate LC patch cords and ensure connectors are clean before insertion. Verify compatibility with the host device's QSFP ports and configure link settings per the network design. For distances approaching the maximum reach, use quality single-mode fiber and maintain proper fiber routing to minimize loss.
