## Summary description

The BlueOptics QSFP-40G-SR4-SW 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 and efficient connectivity.

## Long description

The BlueOptics QSFP-40G-SR4-SW is a QSFP fiber optic transceiver module engineered for short-range, high-speed data transmission. With support for a maximum data rate of 40,000 Mbit/s and operation at an 850 nm wavelength, this module delivers four-channel parallel optical connectivity suitable for modern data center and high-performance computing networks. The compact QSFP form factor enables high port density and straightforward integration into compatible switches and servers.
Advantages
The module provides 40 Gbit/s aggregate bandwidth in a single QSFP package while maintaining low power consumption and heat generation compared to multiple SFP+ ports. Operating at 850 nm, it is optimized for multimode fiber installations and short-reach links. The standardized QSFP interface ensures interoperability with equipment that supports QSFP SR4 modules, enabling easy upgrades to higher-density optical links without changing cabling infrastructure when multimode fiber is already deployed.
Suitable for
 Short-reach 40 Gbit/s uplinks and interconnects in data centers
 High-performance computing clusters requiring aggregated bandwidth
 Switch-to-switch or switch-to-server connections over multimode fiber
 Fiber channel consolidation where QSFP port density is needed
Key specifications
 Interface type: QSFP (Quad Small Form-factor Pluggable)
 Maximum data transfer rate: 40,000 Mbit/s (40 Gbit/s aggregate)
 Operating wavelength: 850 nm
 Form factor: QSFP optical transceiver module
 Optimized for: multimode fiber, short-reach links
How to use
Insert the QSFP transceiver into a compatible QSFP port on a switch, router or server following the host device manufacturer’s hot-plug guidance. Connect appropriate multimode fiber patchcords to the transceiver’s MPO/MTP-compatible connector or adapter as required by the system. Once seated, verify link status and speed in the host device management interface and ensure fiber polarity and lane mapping match the connected equipment. Observe ESD precautions when handling the module and keep protective dust caps on optical interfaces until physical connection is made.
Usage recommendations
Use the BlueOptics QSFP-40G-SR4-SW with OM3 or OM4 multimode fiber for reliable short-reach performance. Confirm compatibility with the host device for QSFP SR4 modules and verify link aggregation or lane configuration if deploying in trunk or breakout scenarios. Maintain connectors clean and inspect fiber ends to minimize insertion loss and reduce the risk of link degradation.
