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

The BlueOptics QSFP-40G-ESR4-IX-BO is a compact QSFP transceiver module designed for 40 Gigabit Ethernet links over multi-mode fiber. It supports a maximum data transfer rate of 40 Mbit/s at an 850 nm wavelength, uses an MPO/MTP fiber connector and is specified for link distances up to 300 m. The module is lightweight (approximately 40 g) and built to industry MSA standards for electrical, mechanical and functional compatibility with QSFP ports.

Advantages

This BlueOptics transceiver provides MSA-compliant interoperability with compatible QSFP ports, enabling plug-and-play replacement or expansion of 40 Gigabit Ethernet connections. It implements optical transmit and receive functions at 850 nm and supports up to 300 m over multimode fiber, offering a balance of short-reach performance and compact form factor. The product is tested for compatibility and uses components selected for stable operation and long mean time between failures.

Suitable for

• 40 Gigabit Ethernet links in data centers and campus networks
• Interconnects between switches, routers and storage systems
• High-density aggregation and uplink ports using MPO/MTP cabling
• Short-reach multimode fiber backbone segments (up to 300 m)

How to use

Install the transceiver into a compatible QSFP slot on a switch, router or other network equipment while following the device vendor's hot‑swap and electrostatic discharge (ESD) precautions. Connect an MPO/MTP multimode fiber patch cord between this module and the corresponding transceiver or patch panel. Configure the network equipment for 40 Gigabit Ethernet operation if required and verify link status through the host device. Ensure that the connected fiber type, patch cord quality and channel components meet multimode specifications to achieve the rated 300 m range.

Recommendations

Use high-quality MPO/MTP patch cords and organized patch panels for reliable performance, and confirm that the host hardware supports DDM/DOM features if remote diagnostics are required. Follow vendor guidelines for cleaning fiber connectors and for ESD protection when inserting or removing the transceiver.
