## Summary description

The BlueOptics QSFP-40G-SR4 is a fiber optic transceiver module designed for high-speed data transfer. It supports a maximum data rate of 40000 Mbit/s and operates at a wavelength of 850 nm. This module is ideal for data centers and high-performance computing environments, providing reliable connectivity and efficient data transmission.

## Long description

The BlueOptics QSFP-40G-SR4 network transceiver module is a hot-pluggable optical module engineered for short-range 40 Gigabit Ethernet links. It supports a maximum data transfer rate of 40000 Mbit/s and transmits using an 850 nm VCSEL-based optical interface. Designed for rack environments, the QSFP form factor consolidates four lanes into a single pluggable unit to enable high-density aggregation and straightforward integration into compatible switches, routers and network interface cards.
Advantages
The module provides compact, high-bandwidth connectivity in a QSFP form factor that reduces port density and cable complexity compared with multiple SFP modules. Operation at 850 nm enables established multimode fiber compatibility for short-reach links. The transceiver supports standardized electrical and optical interfaces for interoperability with equipment that accepts QSFP short-range modules, delivering predictable performance and stable throughput at the specified 40 Gbit/s class.
Suitable for
 40 Gigabit Ethernet connections in data center aggregation and spine-leaf architectures
 High-performance computing clusters requiring short-reach, high-throughput links
 Switch-to-switch or switch-to-server links over multimode fiber within racks or between adjacent racks
Key specifications
 Form factor: QSFP (quad small form-factor pluggable)
 Maximum data transfer rate: 40000 Mbit/s
 Operating wavelength: 850 nm
 Optical medium: multimode fiber (short-reach applications)
 Typical application: 40 Gigabit Ethernet
 Hot-pluggable design for tool-free installation and replacement
How to use
Install the transceiver into a compatible QSFP port on a switch, router or network interface card while the host device is powered on if the equipment supports hot-plugging. Ensure you use appropriate multimode fiber patch cords and correct polarity when connecting. Verify link status and negotiated speed via the host device management interface or CLI after insertion. Follow any vendor-specific provisioning steps required by the network equipment, such as enabling the port or configuring VLANs and link aggregation if needed.
Usage recommendations
Use high-quality OM3 or OM4 multimode fiber for optimal short-reach performance and maintain clean fiber connectors to minimise insertion loss. Confirm compatibility with the host equipment's supported QSFP short-range modules and keep firmware or driver software up to date for reliable operation.
