Modulo ricetrasmettitore QSFP BlueOptics QSFP-40G-SR4-SW 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-SW is a QSFP fiber optic transceiver module engineered for short-range, high-speed data transmission. With support for a maximum data rate of 40,000 Mbit/s and operation at an 850 nm wavelength, this module delivers four-channel parallel optical connectivity suitable for modern data center and high-performance computing networks. The compact QSFP form factor enables high port density and straightforward integration into compatible switches and servers.

Advantages

The module provides 40 Gbit/s aggregate bandwidth in a single QSFP package while maintaining low power consumption and heat generation compared to multiple SFP+ ports. Operating at 850 nm, it is optimized for multimode fiber installations and short-reach links. The standardized QSFP interface ensures interoperability with equipment that supports QSFP SR4 modules, enabling easy upgrades to higher-density optical links without changing cabling infrastructure when multimode fiber is already deployed.

Suitable for

• Short-reach 40 Gbit/s uplinks and interconnects in data centers
• High-performance computing clusters requiring aggregated bandwidth
• Switch-to-switch or switch-to-server connections over multimode fiber
• Fiber channel consolidation where QSFP port density is needed

Key specifications

• Interface type: QSFP (Quad Small Form-factor Pluggable)
• Maximum data transfer rate: 40,000 Mbit/s (40 Gbit/s aggregate)
• Operating wavelength: 850 nm
• Form factor: QSFP optical transceiver module
• Optimized for: multimode fiber, short-reach links

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or server following the host device manufacturer’s hot-plug guidance. Connect appropriate multimode fiber patchcords to the transceiver’s MPO/MTP-compatible connector or adapter as required by the system. Once seated, verify link status and speed in the host device management interface and ensure fiber polarity and lane mapping match the connected equipment. Observe ESD precautions when handling the module and keep protective dust caps on optical interfaces until physical connection is made.

Recommendations

Use the BlueOptics QSFP-40G-SR4-SW with OM3 or OM4 multimode fiber for reliable short-reach performance. Confirm compatibility with the host device for QSFP SR4 modules and verify link aggregation or lane configuration if deploying in trunk or breakout scenarios. Maintain connectors clean and inspect fiber ends to minimize insertion loss and reduce the risk of link degradation.
