## Summary description

The BlueOptics N-QSFP28-SR4-BO is a fiber optic transceiver module designed for high-speed data transfer at 100000 Mbit/s over 850 nm wavelength. It features a QSFP28 interface, metal housing, and operates at an input voltage of 3.3 V. Weighing only 20 g, it is compact and efficient for networking applications.

## Long description

The BlueOptics N-QSFP28-SR4-BO is a fiber optic transceiver module engineered for 100000 Mbit/s short-reach links using an 850 nm wavelength. The module uses a QSFP28 interface and a metal housing, and it operates at a 3.3 V input. With a compact form factor and a weight of 20 g, this silver-coloured transceiver is suitable for high-density networking equipment and data centre installations where space and reliable 100 Gb/s connectivity are required.
Advantages
The transceiver provides 100 Gb/s aggregate throughput via the QSFP28 form factor, supporting high-bandwidth applications while maintaining a small footprint. Its metal housing offers mechanical robustness and thermal dissipation. Operating at 850 nm makes it compatible with multimode fiber links commonly used for short-reach connections. The low weight and standard interface simplify integration into compatible switches, routers and servers.
Suitable for
Short-reach 100 Gb/s links in data centres
High-density switch and router uplinks
Server interconnects and spine-leaf fabrics
Multimode fiber infrastructures using 850 nm optics

How to use
Install the BlueOptics N-QSFP28-SR4-BO into a compatible QSFP28 port on a switch, router or network adapter while the host device is powered down or following hot-swap guidelines from the equipment vendor. Connect the multimode fiber patch cords with the appropriate MPO/MTP connector type for SR4 applications. Verify link status and speed through the host device management interface and ensure transceiver firmware and the device’s compatibility list support the module.
Usage recommendations
Use quality OM3/OM4 multimode fiber for links at 850 nm and maintain proper bend radius and connector cleanliness to ensure signal integrity. Confirm that the network equipment supports QSFP28 SR4 optical modules and consult the switch or server documentation for any vendor-specific compatibility notes.
