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

The BlueOptics QSFP-40G-LR4-20-AO-BO is a quad small form-factor pluggable (QSFP) fiber optic transceiver module designed for 40 Gbit/s links. It supports a maximum data transfer rate of 40,000 Mbit/s and single-mode transmission over long distances up to 20,000 m. The module uses LC fiber connectors and has a compact, lightweight design (approximately 40 g), making it suitable for high-density network equipment in data centers and enterprise backbone networks.

Advantages

This transceiver offers high-bandwidth 40 Gbit/s performance with LR4 wavelength division multiplexing for extended reach over single-mode fiber. The QSFP form factor enables four-channel aggregation and hot-pluggable convenience for flexible maintenance and upgrades. Its lightweight construction and standard LC connector interface ensure compatibility with common fiber patching and rack-mounted switch ports.

Key specifications

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or optical transport device until it seats securely; the module is hot-pluggable, so insertion and removal can be performed without powering down compatible equipment. Connect single-mode LC-format fiber cables to the module's receptacles, taking care to match transmit and receive channels and to maintain fiber cleanliness. Configure the host device for 40 Gbit/s LR4 operation as required by the network design.

Recommendations

Ensure fiber endfaces are clean before connection and use appropriate dust caps when the module is unused. Verify compatibility of the QSFP port and host device firmware with 40G LR4 optics, and test link performance after installation. For long-distance links approaching 20 km, confirm end-to-end optical budget and dispersion budgets meet system requirements.
