Modulo ricetrasmettitore QSFP BlueOptics QSFP-40G-ESR4-NV-BO 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-NV-BO is a QSFP fiber optic transceiver module designed for 40 Gbit/s data transmission over multimode fiber. Operating at an 850 nm wavelength with an MPO/MTP connector and a compact QSFP form factor, the module supports link distances up to 300 m and is intended for use in high-performance networking equipment such as switches, routers and storage systems. The module is silver-coloured, lightweight (0.04 kg) and engineered for long service life with an MTBF of approximately 3,000,000 hours.

Advantages

The transceiver provides high-speed 40 Gbit/s throughput with MPO/MTP connectivity following MSA standards, ensuring broad interoperability with common hardware platforms. Integrated digital diagnostic monitoring (DDM/DOM) enables real-time readout of parameters such as supply voltage, laser current, transmit and receive power, and temperature for simplified maintenance and troubleshooting. The product uses industry-grade optical components to deliver stable optical performance, a compact footprint for dense installations and an extended operating life that reduces maintenance frequency.

How to use

Install the QSFP transceiver into a QSFP-compatible port on your switch, router or storage device following the host equipment manufacturer's hot-plug and handling guidelines. Connect the module to MPL/MTP patch cables or a pre-terminated MPO trunk to establish the multimode fiber link; ensure correct fiber type and polarity. Verify link negotiation and DDM values via the host system management interface to confirm transmit and receive power levels and temperature are within expected ranges before placing the link into production. Handle the transceiver by its edges and use protective dust caps on the MPO/MTP connector when the module is not connected.

Recommendations

Use multimode OM3/OM4 fiber for best performance at 850 nm and distances up to 300 m, and ensure the host device supports QSFP 40GBASE-ESR4 functionality and DDM if you require remote diagnostics. Follow ESD precautions during installation and periodically monitor DDM parameters to detect degradation of optical power or other link issues.
