QSFP transceiver modul BlueOptics QSFP-40G-ESR4-RW-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-RW-BO is a QSFP form-factor fiber optic transceiver module designed for 40 Mbit/s data transmission over multimode fiber at an 850 nm wavelength. It uses an MPO/MTP fiber connector and supports a maximum transfer distance of up to 300 m. With a compact weight of 40 g and an MTBF of 1,000,000 hours, the module is suitable for integration into high-density network hardware that accepts QSFP modules and MSA-compliant optics.

Advantages

This QSFP transceiver provides a QSFP interface compatible with systems that follow MSA specifications, enabling interoperable connections across supported switches, routers and storage platforms. It includes both transmitter and receiver elements operating at 850 nm and is optimized for multimode fiber links. The module's compact size and light weight make it suitable for high-density installations while its long MTBF indicates stable operation over extended service periods.

Suitable for

• 40 Gigabit Ethernet links over multimode fiber
• High-speed connections between switches, routers and storage systems
• Short-reach data center interconnects up to 300 m
• Environments requiring MPO/MTP connectorized fiber cabling

How to use

Install the QSFP module into a compatible QSFP port on supported networking hardware following the equipment manufacturer's hot-swap and handling procedures. Connect MPO/MTP multimode fiber patch cords between the transceiver and the corresponding port or patch panel, ensuring correct fiber polarity and secure connector seating. Verify link status and configure the host device for a 40 Gigabit Ethernet connection where required. Confirm that the host hardware supports the module's diagnostic features if you plan to use digital diagnostics monitoring.

Recommendations

Use multimode fiber rated for short-reach applications and high-quality MPO/MTP patch cords to achieve the specified 300 m range. Verify compatibility with the target switch or router and enable any required firmware or port settings for QSFP modules. If the host supports digital diagnostics monitoring, enable and monitor the available parameters to support troubleshooting and preventive maintenance.
