Módulo transceptor QSFP BlueOptics QSFP-40G-LR4-20-QL-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-QL-BO is a QSFP fiber optic transceiver module engineered for 40 Gbit/s class data links. Designed for single-mode long-reach applications, this compact module supports a maximum data transfer rate of 40,000 Mbit/s and a transmission distance up to 20,000 m using LC fiber optic connections. At 40 g it offers a low-weight form factor suitable for high-density switches and routers where reliable 40G LR4 links are required.

Advantages

This QSFP transceiver provides high-bandwidth, low-latency optical transmission for long-distance single-mode links. The LR4 wavelength-division multiplexing design enables four-channel operation over a single fiber pair, reducing cabling complexity. Its QSFP interface supports hot-pluggable installation and interoperability with 40G-capable networking equipment. The LC connector type is widely used and allows straightforward integration with existing fiber infrastructure.

Key specifications

How to use

Install the BlueOptics QSFP-40G-LR4-20-QL-BO by inserting the module into a compatible QSFP port on your switch or router until it seats firmly. Connect LC-terminated single-mode fiber cables to the module’s LC ports, observing correct transmitter/receiver polarity. Configure the network device interface to enable 40G operation as required by your equipment, and verify link status through device diagnostics or management software. The module supports hot-plugging but it is recommended to follow the host device vendor’s guidelines when inserting or removing modules.

Recommendations

Use single-mode LC fiber rated for LR4 transmission and maintain appropriate fiber cleanliness. Ensure proper thermal management and compatibility with the host device’s supported QSFP transceiver list. For long-distance links up to 20 km, verify optical budget and link loss; use appropriate optical amplifiers or dispersion management only if required by the link design.
