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

The BlueOptics QSFP-40G-ESR4-UQ-BO is a QSFP fiber optic transceiver module designed for 40 Gigabit Ethernet applications. It supports a maximum data transfer rate of 40 Mbit/s over multi-mode fiber at an operating wavelength of 850 nm. The module uses an MPO/MTP connector, supports link distances up to 300 m, and offers a lightweight form factor (approx. 40 g) suitable for dense network environments and data center installations. Built to MSA QSFP specifications, the module is compatible with equipment that accepts QSFP-40G 40GBASE-ESR4 optics and includes digital diagnostics monitoring for real-time status information when used in supporting hardware.

Advantages

The transceiver provides standardized QSFP form-factor interoperability, an MPO/MTP multi-fiber connection for high-density cabling, and support for Digital Diagnostics Monitoring (DDM/DOM) to monitor supply voltage, laser current, optical output/input power and temperature. With a specified MTBF of 1,000,000 hours and component selection compliant with industry MSA standards, it offers predictable operational lifetime and maintenance planning. The small, lightweight module simplifies installation and replacement in rack-mounted switches and optical equipment.

• Digital Diagnostics Monitoring (DDM/DOM): supported when the host device provides access

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router, or optical module slot following the host device manufacturer's guidelines for hot-plug transceivers. Connect an MPO/MTP multi-fiber patch cord between the module and the matching MPO/MTP adapter or transceiver at the other end of the link, ensuring correct fiber polarity and connector orientation. Verify link status and diagnostics via the host device management interface if Digital Diagnostics Monitoring is supported. Observe standard electrostatic discharge (ESD) precautions and handle the optical interfaces with protective caps until final connection.

Recommendations

Use multimode OM3/OM4 fiber along with quality MPO/MTP patch cords and maintain correct fiber polarity for best performance. Confirm host device compatibility with QSFP-40G 40GBASE-ESR4 optics and enable DDM/DOM support in the equipment for remote monitoring. Store and operate the module within the temperature and humidity ranges specified by the host hardware vendor and clean connectors before mating to reduce optical loss.
