QSFP-transceiver BlueOptics QSFP-40G-SR4-MT 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-MT is a fiber optic transceiver module designed for short-reach 40 Gbps links. It uses an 850 nm wavelength and a QSFP interface to support aggregated high-speed data transmission in data center and enterprise network environments. The module is compact and lightweight with a silver housing, enabling easy installation into compatible QSFP ports.

Advantages

The transceiver supports a maximum data transfer rate of 40,000 Mbit/s and is engineered for multi-channel parallel optical transmission over multimode fiber. Its QSFP form factor provides hot-pluggable convenience, simplified port consolidation and reduced cabling complexity when used with appropriate MPO/MTP trunking. The 850 nm wavelength is commonly used for short-range multimode applications and offers predictable performance in structured cabling environments.

Suitable for

• 40 Gigabit Ethernet links in data centers and server racks
• High-bandwidth interconnects between switches and aggregation devices
• Short-reach multimode fiber connections using MPO/MTP trunk cables
• Network upgrades requiring QSFP form factor and 40 Gbps capacity

How to use

Install the BlueOptics QSFP-40G-SR4-MT into a compatible QSFP port on a switch, router or network adapter. Ensure the host device supports 40 Gbps QSFP modules and that firmware or configuration settings permit the interface to negotiate at the intended speed. Use appropriate MPO/MTP multimode fiber cabling and verify pinout and polarity before connecting. After insertion, monitor link indicators and perform a link test to confirm correct operation.

Recommendations

Verify compatibility with your network equipment vendor and confirm support for SR4 parallel multimode operation. Use OM3/OM4 multimode fiber for optimal reach at 850 nm and keep connectors clean to maintain signal quality. Follow standard ESD precautions when handling the transceiver and store unused modules in protective packaging.
