QSFP-transceiver BlueOptics QSFP-40G-SR4-SP-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-SP-BO is a QSFP fiber optic transceiver designed for multi-mode fiber links with a nominal wavelength of 850 nm and a maximum data transfer rate of 40 Mbit/s. The module comes in a metal housing, operates from a 3.3 V supply and has a documented mean time between failures (MTBF) of 1,000,000 hours. The compact transceiver weighs approximately 20 g and uses an MPO/MTP-style optical interface for 40GBASE-SR4-compatible operation.

Advantages

The module provides a standardized QSFP interface and metal housing for mechanical robustness and thermal dissipation. With a specified MTBF of 1,000,000 hours and industry-standard wavelength of 850 nm, the transceiver is intended for stable short-reach multimode fiber connections. The 3.3 V operating voltage and small form factor support integration in a wide range of network devices that accept QSFP transceivers.

Suitable for

• 40G multimode fiber links in data center aggregation and spine/topology
• High-speed connections between switches, routers and storage systems
• Short-reach campus or enterprise backbone segments using MPO/MTP cabling

How to use

Install the transceiver into a compatible QSFP port on a switch, router or storage device while the host is powered down or following the vendor's hot-plug guidelines. Connect the MPO/MTP multi-mode fiber patch cord to the transceiver ensuring correct polarity and secure mating. Verify link status and parameters through the host device management interface and, if available, check diagnostic information provided by the transceiver. Follow the system vendor's instructions for enabling 40GBASE-SR4 operation and any required firmware or software settings.

Recommendations

Use high-quality OM3/OM4 multimode fiber with MPO/MTP connectors and keep connector endfaces clean to ensure expected link performance; confirm host compatibility with QSFP-40G-SR4-SP-BO before deployment and observe manufacturer guidelines for hot-plugging and handling static-sensitive components.
