Ricetrasmettitore QSFP BlueOptics QSFP-40G-CSR4-BO 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-CSR4-BO is a QSFP form-factor fiber optic transceiver module designed for 40 Gbit/s links. It supports a maximum data transfer rate of 40000 Mbit/s over multimode fiber at an 850 nm wavelength and is specified for reach up to 400 m. Built with a stainless steel housing and compatibility with Cisco equipment, this module is intended for deployment in data centers and enterprise networks that require compact, hot-pluggable, high-density optical connectivity.

Advantages

The module's QSFP interface provides four-channel aggregation in a single compact transceiver, enabling space-efficient 40 Gbit/s connections. Stainless steel construction offers robust mechanical durability and effective shielding. Native operation at 850 nm on multimode fiber enables cost-effective short-reach links up to 400 m, while compatibility with common networking equipment simplifies integration into existing infrastructures.

Suitable for

• 40 Gbit/s uplinks in data center racks
• Switch-to-switch or switch-to-server connections over multimode fiber
• High-density aggregation panels and optical patching
• Enterprise backbone segments requiring short-reach, high-throughput links

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Maximum data transfer rate: 40000 Mbit/s
• Operating wavelength: 850 nm
• Maximum reach on multimode fiber: up to 400 m
• Housing material / colour: stainless steel
• Compatibility: compatible with Cisco equipment and other QSFP-capable devices

How to use

Insert the BlueOptics QSFP-40G-CSR4-BO into a compatible QSFP port while the host device is powered according to the vendor's hot-plug guidelines. Connect the multimode fiber patch cords to the transceiver's optical interface, ensuring correct polarity and clean connectors. After physical installation, verify the link status in the switch or transceiver diagnostics and configure the host ports and VLANs as required. Follow equipment vendor guidance for any required firmware or compatibility settings.

Recommendations

Use OM3/OM4 multimode fiber for reliable performance at the specified 400 m reach, keep connector endfaces clean using proper cleaning tools, and store spare transceivers in anti-static packaging. When integrating with third-party equipment, verify interoperability notes from the switch vendor to ensure full feature and link stability.
