QSFP Transceiver Module BlueOptics QSFP-40G-ESR4-PS-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-PS-BO is a QSFP fiber optic transceiver module designed for 40 Gigabit Ethernet links over multimode fiber. It supports a maximum data transfer rate of 40 Mbit/s at an operating wavelength of 850 nm, offers a maximum reach of up to 300 m over suitable multimode fiber, and features an MTP/MPO fiber connector for parallel optics. The module is compact and lightweight (approximately 0.04 kg) and provides monitoring capability through Digital Diagnostic Monitoring (DDM/DOM) when the host hardware supports this feature.

Advantages

The transceiver is manufactured according to QSFP MSA standards to ensure interoperability with equipment that supports 40GBASE-ESR4 QSFP modules. It integrates standardized transmit and receive optics at 850 nm and is tested for compatibility and functionality with common hardware platforms. With an MTBF of 1,000,000 hours, the module is designed for long operational life and reduced maintenance. The use of an MTP/MPO connector enables parallel multimode fiber connections commonly used in data center spine and leaf topologies.

Suitable for

• 40 Gigabit Ethernet interconnects in data center switching and routing
• High-density multimode fiber links in server racks and patch panels
• Short- to medium-reach optical links up to 300 m over multimode fiber

How to use

Install the QSFP module into a compatible QSFP port on a switch, router or other networking device that supports 40GBASE-ESR4 transceivers and the QSFP MSA. Ensure the host device supports the DDM/DOM feature if remote diagnostic monitoring is required. Connect an appropriate MTP/MPO multimode fiber patch cord between transceivers or to a compatible patch panel, observing correct fiber polarity and ribbon alignment. After insertion and link-up, verify link status and diagnostic values in the host management interface. Follow the vendor instructions for hot-plug handling to avoid physical damage.

Recommendations

Use OM3/OM4 multimode fiber for best reach and performance up to 300 m and choose high-quality MTP/MPO patch cords and proper cleaning procedures. Verify compatibility with the target hardware platform and, where possible, test a sample in your environment to confirm expected operation and DDM visibility.
