QSFP Transceiver Module BlueOptics QSFP-40G-SR4-S 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-S is a QSFP fiber optic transceiver module engineered for 40 Gbit/s short-range links over multimode fiber. It transmits at an 850 nm wavelength and supports multimode distances up to 100 metres, making it suitable for high-density network environments such as data centres and high-performance computing racks. The module uses the QSFP form factor for compact port density and high aggregate throughput.

Advantages

The QSFP-40G-SR4-S offers a standardized QSFP interface that enables straightforward interoperability with compatible switches and servers. Its 40 Gbit/s maximum data transfer rate provides high bandwidth for aggregation and spine connections. Operating at 850 nm on multimode fiber reduces cost for short-reach links while maintaining reliable optical performance. The compact QSFP form factor supports high port density in equipment racks.

Key specifications

How to use

Install the module into a compatible QSFP port on a switch, router or server according to the host equipment manufacturer guidelines. Connect the multimode fiber patch cable ensuring correct polarity and LC/ MPO connector type matching as required by the transceiver and cabling infrastructure. After insertion, verify link status and negotiated speed through the host device management interface and monitor optics diagnostics if available.

Recommendations

Use high-quality OM3/OM4 multimode fiber patch cords for optimal performance up to the specified 100 m distance. Confirm compatibility with the host device and, if necessary, update device firmware or consult interoperability lists to ensure reliable operation. Avoid exposure to excessive dust or physical stress on connectors when installing or servicing the module.
