BlueOptics ONS-QSFP-40G-SR4= netwerk-transceivermodule 40000 Mbit/s 850 nm

The BlueOptics ONS-QSFP-40G-SR4= network transceiver module is a quad small form-factor pluggable (QSFP) device engineered for short-reach multimode fiber links. It supports a maximum data transfer rate of 40,000 Mbit/s and uses an 850 nm wavelength, making it suitable for high-density networking in data centers and high-performance computing clusters. The module's compact QSFP form factor and silver housing allow hot-plug installation into compatible switches, routers and server optics ports.

Advantages

This QSFP transceiver provides high-speed 40 Gbit/s connectivity over multimode fiber with a standardized 850 nm optical interface. Its compact QSFP package supports high port density and simplifies upgrades from lower-speed modules. The lightweight silver module is designed for hot-swap operation and interoperates with equipment that accepts QSFP form-factor optics, offering predictable optical performance for short-range links.

Suitable for

• Data center intra-rack and inter-rack connectivity
• High-performance computing clusters and server farms
• Short-reach multimode fiber links (e.g., within campus or building)
• Network upgrades requiring 40 Gbit/s aggregate throughput

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on a switch, router or server optics module while the system is powered according to the host equipment manual. Connect appropriate multimode fiber patch cords and verify link status through the host device management interface. Ensure transceiver and host equipment settings (speed, duplex and lane mapping if applicable) match to establish a stable 40 Gbit/s connection.

Recommendations

Use OM3 or OM4 multimode fiber for reliable short-range 40 Gbit/s transmission at 850 nm and follow fiber handling best practices: keep connectors clean, avoid tight bends, and verify link budget against cable plant characteristics. Confirm compatibility with the host device's optical specifications before deployment.
