## Long description

The BlueOptics QSFP-40G-LR4-20-CP-BO is a QSFP fiber optic transceiver module engineered for 40 Gbit/s data links. Designed for use in high-density network environments, this compact 40 g module provides long-reach single-mode connectivity suitable for data centers and enterprise backbones. The transceiver implements the QSFP interface and is optimized for reliable transmission over extended distances while keeping a small form factor and low weight.
Advantages
This QSFP transceiver supports a maximum data transfer rate of 40,000 Mbit/s, enabling aggregation and high-throughput connections between switches, routers and servers. Its QSFP interface ensures compatibility with equipment that accepts quad small form-factor pluggable modules and simplifies hot-swap maintenance. The lightweight design (approximately 0.04 kg) reduces handling load in dense rack installations and contributes to efficient airflow and space utilization.
Suitable for
 40 Gbit/s uplinks between core and aggregation switches
 Long-distance single-mode fiber connections in data centers
 High-bandwidth server interconnects and storage area networks
 Enterprise backbone links and campus network cores
Key specifications
 Interface type: QSFP (Quad Small Form-factor Pluggable)
 Maximum data transfer rate: 40,000 Mbit/s (40 Gbit/s)
 Form factor: QSFP module for hot-pluggable ports

How to use
Install the BlueOptics QSFP-40G-LR4-20-CP-BO into a compatible QSFP port on your switch, router or server while the host device is powered on or off, as supported by the equipment's hot-swap capability. Connect the single-mode fiber patch cables to the transceiver’s optical interface following the correct polarity. Verify link status and configuration in the host equipment’s management interface and configure the port for the required speed and multiplexing settings. Monitor the link for proper operation and replace the module if diagnostics indicate a failure.
Usage recommendations
Use single-mode fiber cables and appropriate LC/MPP breakout assemblies compatible with LR4 QSFP modules. Ensure transceiver compatibility with the host device firmware and optical specifications before deployment, and follow ESD precautions during handling. For optimal performance, verify link budgeting and perform end-to-end testing after installation.
