## Long description

The BlueOptics QFX-QSFP-40G-LR4 network transceiver module is a fiber optic QSFP device engineered for high-speed links up to 40000 Mbit/s. Designed for use in data centers and enterprise networks, this module provides a compact QSFP interface that supports long-reach single-mode fiber connections. The transceiver is intended to integrate into compatible switches and routers to deliver stable, high-bandwidth optical connectivity.
Advantages
This QSFP transceiver supports a 40000 Mbit/s maximum data transfer rate and offers a standardized QSFP form factor for easy installation and hot-pluggable replacement. Its fiber optic design enables lower latency and extended reach compared with copper alternatives, improving link reliability over longer distances. The module is suitable for environments that require consolidated high-throughput links and predictable optical performance.
Suitable for
40 Gigabit Ethernet uplinks between switches and aggregation devices
Data center interconnects over single-mode fiber
High-bandwidth server connectivity and virtualization backbones
Enterprise core and distribution layer links requiring long-reach optics
Key specifications
Interface type: QSFP
Maximum data transfer rate: 40000 Mbit/s
Media: single-mode fiber (long-reach optical design)
Form factor: QSFP pluggable module
How to use
Install the module into a compatible QSFP port on a switch or router while the port is enabled for hot-pluggable transceivers. Connect appropriate single-mode fiber cables with matching LC duplex or MPO connectors as required by the host equipment. Verify link status through the host device management interface and monitor signal indicators to confirm successful optical negotiation at 40 Gbit/s. Follow standard electrostatic discharge (ESD) precautions during handling and keep protective caps on the optical ports when not in use.
Usage recommendations
For reliable operation, use single-mode fiber rated for long-reach links and ensure cleaning of fiber end faces before connection. Validate compatibility with the host device's supported transceiver list and firmware, and test links after installation to confirm throughput and error rates.
