QSFP-transceivermodule BlueOptics QSFP-40G-SR4-UQ-BO 850 nm MPO 150 m

The BlueOptics QSFP-40G-SR4-UQ-BO is a QSFP transceiver module designed for 40G optical links over multimode fiber. Operating at an 850 nm wavelength with an MPO connector, it supports data transmission distances up to 150 m. The module is lightweight (approximately 20 g) and finished in silver, providing a compact, standardized QSFP form factor for integration into compatible network hardware.

Advantages

This QSFP transceiver follows MSA-aligned QSFP electrical and mechanical standards to ensure interoperability with devices that accept compatible QSFP modules. The 850 nm transmitter and receiver combination is intended for short-range multimode fiber applications and enables aggregated 40GBASE-SR4 links using MPO connectivity. The compact, lightweight design makes it convenient for dense switch and router environments while preserving the form factor expected by QSFP ports.

Suitable for

• 40G Ethernet connections over multimode fiber within data centers
• Inter-switch links and aggregation in campus or enterprise networks
• Short-range high-bandwidth connections such as storage area networks

How to use

Install the BlueOptics QSFP-40G-SR4-UQ-BO by inserting the module into a compatible QSFP port on a switch, router or other network device that supports QSFP transceivers. Connect an MPO-terminated multimode fiber patch cable between transceivers or to a patch panel. Ensure the host device firmware and interface accept third-party QSFP modules if required by the hardware vendor. Power up the device and verify the link status and negotiated speed through the host system management interface.

Recommendations

Use high-quality multimode fiber patch cords and maintain proper polarity when connecting MPO links. Verify compatibility and DDM/DOM support with the host hardware if real-time diagnostic monitoring is required. For best performance, follow manufacturer guidance for cleanliness of fiber connectors and proper cable routing to avoid bending beyond specified limits.
