## Summary description

The BlueOptics QSFP-40G-LR4-20-QL-BO is a fiber optic transceiver module designed for high-speed data transfer with a maximum rate of 40000 Mbit/s. It features a QSFP interface and weighs 40 g, making it suitable for various networking applications.

## Long description

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.
Suitable for
Long-reach single-mode links in campus and metropolitan networks
Interconnects between data center switches and aggregation layers
Upgrading 10G infrastructure to 40G backbone links
Carrier and service provider optical transport segments
Key specifications
Maximum data transfer rate: 40000 Mbit/s
Maximum transfer distance: 20000 m (single-mode, LR4)
Form factor: QSFP (hot-pluggable)
Fiber optic connector: LC
Weight: 0.04 kg
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.
Usage 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.
