Módulo transceptor QSFP BlueOptics QSFP-40G-ESR4-PA-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-PA-BO is a QSFP fiber optic transceiver module designed for high-speed multimode fiber links. It supports up to 40 Mbit/s data transfer at an 850 nm wavelength and uses an MPO/MTP connector for parallel optical connections. With a compact, lightweight design (approximately 40 g) and an MTBF of 1,000,000 hours, the module is intended for reliable deployment in network equipment that accepts QSFP 40 Gigabit Ethernet optics.

Advantages

The module follows MSA-compliant QSFP mechanical and electrical specifications and is built for compatibility with systems that support equivalent 40GBASE-ESR4 transceivers. It supports simultaneous transmit and receive channels over multimode fiber, provides a practical maximum reach of up to 300 m, and is fitted with an MPO/MTP connector for high-density installations. The lightweight form factor simplifies installation and hot-swap replacement in switches, routers and other network hardware.

Suitable for

• Short-reach 40 Gigabit Ethernet links over multimode fiber
• Data center aggregation and spine-leaf interconnects
• High-density patch panels and optical distribution frames using MPO/MTP cabling
• Switches, routers and storage systems that accept QSFP optical modules

Key specifications

• Maximum data transfer rate: 40 Mbit/s
• Wavelength: 850 nm
• Maximum transfer distance over multimode fiber: 300 m
• Ethernet interface type: 40 Gigabit Ethernet
• Fiber optic connector: MTP/MPO
• Weight: 0.04 kg
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the QSFP transceiver into a compatible QSFP port on the network device following the equipment manufacturer’s hot-swap and handling procedures. Connect an MPO/MTP multimode patch cord to the module and route fibers to the corresponding parallel transceiver or patch panel. Verify link status and, if available, monitor the module with the host device’s diagnostic interface. Ensure the connected fiber type and patching topology match the module’s ESR4 multimode application to achieve the specified reach.

Recommendations

To maintain performance and lifetime, use high-quality multimode MPO/MTP patch cords, avoid excessive bending or stress on fiber cables, and confirm that the host hardware supports QSFP 40GBASE-ESR4 optics and any digital diagnostic monitoring features you plan to use.
