Modulo ricetrasmettitore QSFP BlueOptics QSFP-40G-ESR4-QL-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-QL-BO is a QSFP transceiver module designed for 40 Gigabit Ethernet over multimode fiber. It operates at an 850 nm wavelength and supports a maximum data transfer rate of 40 Mbit/s with a maximum reach of up to 300 m using MPO/MTP connectors. The module is compact and lightweight (approximately 40 g) and is manufactured to MSA-compliant QSFP specifications for interoperability with compatible network hardware. Built with a focus on digital diagnostics and long operational lifetime, the transceiver provides real-time monitoring of optical and electrical parameters when supported by the host device.

Advantages

The transceiver offers standardized QSFP form-factor compatibility and MPO/MTP connectivity for parallel multimode links, enabling straightforward integration into existing 40 Gigabit Ethernet infrastructures. It incorporates Digital Diagnostics Monitoring (DDM/DOM) to report supply voltage, laser bias current, output and received power and temperature, which supports remote monitoring and maintenance. Components are selected to meet industry standards and the module is designed for long MTBF performance to reduce maintenance frequency in critical network environments.

Suitable for

• Aggregation and spine switches in data centers
• High-speed uplinks between network devices
• Server and storage interconnects supporting 40 Gigabit Ethernet
• Short-range multimode fiber links in campus and enterprise networks

How to use

Install the QSFP transceiver into a compatible QSFP slot on a switch, router or other 40G-capable device following the host vendor’s hot-plug and ESD safety procedures. Connect an MPO/MTP multimode fiber patch cable to the transceiver and to the corresponding MPO/MTP connector on the remote transceiver or patch panel. Verify link status in the host device management interface and enable DDM/DOM monitoring if the platform supports it. Use appropriate multimode fiber grade (e.g., OM3/OM4) to achieve the specified reach and maintain correct polarity and channel mapping for parallel lanes.

Recommendations

For reliable operation, use OM3 or OM4 multimode fiber and quality MPO/MTP patch cords, ensure proper port configuration on both ends, and confirm host firmware supports third-party QSFP modules and DDM/DOM if remote diagnostics are required. Observe ESD precautions during handling and consider testing a sample in your environment to validate compatibility with your specific hardware and cabling.
