## Summary description

The BlueOptics QSFP-40G-LR4 is a fiber optic transceiver module designed for high-speed data transfer up to 40000 Mbit/s. It features a QSFP interface, making it suitable for various networking applications. This module is ideal for long-distance connections, ensuring reliable performance and high bandwidth.

## Long description

The BlueOptics QSFP-40G-LR4 network transceiver module 40000 Mbit/s is a fiber optic module designed for high-speed, long-reach network links. With a QSFP interface and support for 40 Gbit/s throughput, the module is intended for use in switches, routers and servers where consolidated 40 Gigabit Ethernet or Infiniband connections are required over single-mode fiber.
Advantages
The transceiver combines a compact QSFP form factor with four-lane optical transmission to deliver up to 40 Gbit/s aggregate bandwidth while occupying a single port. It supports long-distance links over single-mode fiber, offering predictable signal integrity and low latency for backbone and data center interconnects. The module is hot-pluggable and interoperable with standard QSFP ports, simplifying installation and maintenance.
Suitable for
40 Gigabit Ethernet uplinks in data centers
Aggregation links between core and distribution switches
Server-to-switch high-speed connections
Long-distance single-mode fiber links between buildings or campuses
Key specifications
Interface type: QSFP (Quad Small Form-factor Pluggable)
Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s aggregate)
Optical medium: single-mode fiber (long-reach LR4 architecture)
Form factor: QSFP multi-lane transceiver
Hot-pluggable for live insertion and removal
How to use
Install the BlueOptics QSFP-40G-LR4 into a compatible QSFP slot on the network device, ensuring the port and transceiver are rated for 40 Gbit/s operation. Connect appropriate single-mode fiber cables using the correct LC or MPO connector type as required by the LR4 implementation, and verify link status through the device management interface. Follow device vendor guidance to configure link aggregation, speed settings and any required transceiver diagnostics.
Usage recommendations
Verify compatibility with the host device and use single-mode fiber rated for long-reach LR4 transmission. Keep fiber connectors clean and avoid excessive bending of fiber cables. Monitor link status and transceiver diagnostics regularly to ensure consistent 40 Gbit/s performance.
