## Summary description

The BlueOptics 40G-QSFP-SR4-INT 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 QSFP interface module is ideal for data centers and high-performance computing environments, providing reliable connectivity and efficient data transmission.

## Long description

The BlueOptics 40G-QSFP-SR4-INT is a fiber optic transceiver module engineered for high-speed short-reach data transmission. Designed for QSFP ports, it supports a maximum data transfer rate of 40,000 Mbit/s and operates at an 850 nm wavelength. The module is intended for use in network equipment that accepts QSFP form-factor transceivers and is suited for 40 Gigabit Ethernet links over multimode fiber in data center and high-performance computing environments.
Advantages
This QSFP SR4 transceiver delivers consistent 40 Gbit/s performance with low latency and stable optical characteristics at 850 nm. Its compact QSFP form factor provides high port density and allows easy hot-plug installation into compatible switches and routers. The module is designed for short-range multimode fiber links, offering reliable connectivity for aggregated uplinks and server-to-switch connections while minimizing cabling complexity.
Suitable for
 40 Gigabit Ethernet links over multimode fiber (short reach)
 Data center uplinks and aggregation
 High-performance computing clusters and interconnects
 Switch-to-switch and server-to-switch connections within the same campus or rack
Key specifications
 Interface type: QSFP (Quad Small Form-factor Pluggable)
 Maximum data transfer rate: 40,000 Mbit/s
 Operating wavelength: 850 nm
 Optical medium: multimode fiber (designed for short range / SR4)
 Typical application: 40GBASE-SR4 networks
How to use
Install the transceiver into a compatible QSFP port on a switch, router or network interface card following the host equipment guidelines. Ensure the transceiver and host port are powered off or follow the vendor’s hot-plug instructions if supported. Connect appropriate multimode fiber cables with matched MPO/MTP connectors and verify link status through the host device management interface. Monitor signal and link indicators to confirm correct operation and troubleshoot using host diagnostics if required.
Usage recommendations
Use quality multimode fiber and clean connectors to maintain signal integrity; adhere to the supported short-reach distance specifications for SR4 optics. Confirm compatibility with the host device’s QSFP port and firmware, and replace or reseat the module only when the link is down or according to the equipment maker’s hot-swap guidelines.
