## Long description

The BlueOptics QSFP-40G-ESR4-MV-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s high-speed links over multimode fiber. Operating at an 850 nm wavelength and fitted with an MTP/MPO fiber connector, the module supports 40 Gigabit Ethernet interfaces and provides a maximum reach of up to 300 m. The compact transceiver weighs approximately 40 g and is built to MSA-compliant QSFP mechanical and electrical standards to ensure interoperability with compatible network hardware. The module includes digital diagnostic monitoring capabilities for real-time status information and is specified with a mean time between failures (MTBF) of 1,000,000 hours to support long-term availability.
Advantages
The module delivers standardized QSFP connectivity for 40G applications and uses an 850 nm transmitter/receiver optimized for multimode fiber. Compliance with QSFP MSA and use of quality components supports predictable interoperability across switches, routers, and storage systems that accept standard QSFP modules. With digital diagnostic monitoring (DDM/DOM), the transceiver provides remote readout of supply voltage, laser bias and optical power levels, and temperature, which simplifies troubleshooting and maintenance. Lightweight and compact, the transceiver is straightforward to install and replace in compatible hardware.
Suitable for
40 Gigabit Ethernet uplinks and aggregation links in data centers
High-speed connections between switches, routers and storage arrays
Short-reach multimode fiber runs up to 300 m using MTP/MPO cabling
Environments requiring remote monitoring of optical link parameters

How to use
Install the BlueOptics QSFP-40G-ESR4-MV-BO by inserting the QSFP module into a compatible QSFP slot on the network device until it latches. Connect an MTP/MPO multimode fiber patch cable to the module’s connector, ensuring proper ribbon orientation and polished endface cleanliness. Verify that the host device recognizes the transceiver and, if available, read DDM/DOM data through the device management interface to confirm link health. When removing the module, power down or follow hot-swap procedures recommended by the equipment vendor and handle the transceiver and fiber connectors carefully to avoid contamination or damage.
Usage recommendations
For optimal performance, use multimode fiber and MTP/MPO patch cords rated for 850 nm operation and maintain clean connector endfaces. Confirm that the host hardware supports QSFP modules with DDM/DOM to access diagnostic data. Follow vendor guidelines for hot-swap handling, and consider testing a sample module in your specific equipment to confirm compatibility before large-scale deployment.
