Fiber optic transceiver BlueOptics SM40G-SR 40000 Mbit/s QSFP 850 nm

The BlueOptics SM40G-SR is a fiber optic transceiver module engineered for high-speed short-reach links. With a QSFP interface and a maximum data transfer rate of 40000 Mbit/s, this module supports aggregation and high-density switching environments. It operates at an 850 nm wavelength and has a compact, lightweight silver housing weighing approximately 20 g, suitable for rack-mounted switches and servers where space and power efficiency are important.

Advantages

The module delivers 40 Gbit/s aggregate bandwidth over multimode fiber with a standardized QSFP form factor for easy installation into compatible ports. Its small size and 20 g weight reduce mechanical strain on ports and cabling, while the 850 nm operating wavelength is widely supported for short-reach data center connections. The silver casing provides physical protection and consistent thermal performance without adding significant bulk.

How to use

Insert the BlueOptics SM40G-SR transceiver into a compatible QSFP port on a switch, router or network appliance, ensuring proper orientation and secure seating. Connect multimode fiber patch cords appropriate for 850 nm operation and confirm link status via the host device's port indicators or management interface. Follow the host equipment's procedures for module recognition and any required link configuration. Handle the module by the body, avoid touching the optical interfaces, and use dust caps when the transceiver is not connected.

Recommendations

For reliable short-reach performance, use multimode fiber rated for 850 nm and maintain clean connectors. Verify QSFP compatibility with the host device and consult vendor documentation for any firmware or compatibility notes. Observe ESD precautions during installation and store spare modules in protective packaging to prevent contamination or mechanical damage.
