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

The BlueOptics QSFP-40G-LR4-20-LO-BO is a QSFP form-factor fiber optic transceiver module engineered for 40 Gbit/s data links. Designed for long-reach singlemode operation, this module supports optical transmission over distances up to 20,000 meters and uses LC connectors for fiber termination. With a compact QSFP interface and a lightweight 40 g housing, it integrates into compatible switches, routers and media converters to enable high-speed uplink and aggregation channels.

Advantages

This module delivers 40,000 Mbit/s throughput in a QSFP package, combining high bandwidth with long-reach capability. The LR4 wavelength division multiplexing design provides reliable transmission over singlemode fiber for metro and campus links. Its LC connector interface ensures broad compatibility with standard fiber patching and allows straightforward replacement or upgrade of existing transceivers. The lightweight construction simplifies handling and installation in dense rack environments.

How to use

Install the BlueOptics QSFP-40G-LR4-20-LO-BO into a compatible QSFP slot on the network device following the device manufacturer's instructions. Ensure the transceiver and host port support 40 Gbit/s operation and singlemode LC fiber connections. Connect LC fiber patch cables—observing correct transmit/receive polarity—and secure all fiber connections. After insertion, verify link status and speed through the host device management interface and perform any necessary optical power checks to confirm adequate signal margins.

Recommendations

Use certified singlemode fibers and quality LC patch cords to maintain signal integrity over long distances. Verify compatibility with the host device for QSFP LR4 transceivers and check link diagnostics after installation. Handle the module by its edges, keep protective dust caps on when not connected, and follow ESD precautions during installation.
