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

The BlueOptics QSFP-40G-ESR4-SW-BO is a QSFP fiber optic transceiver module for 40 Mbit/s links over multimode fiber. Operating at an 850 nm wavelength and equipped with an MTP/MPO connector, this compact module supports 40 Gigabit Ethernet interfaces with a maximum reach of up to 300 m. The unit is lightweight (approx. 40 g) and designed for long operational service with a specified MTBF of 1,000,000 hours.

Advantages

This transceiver follows MSA-compliant QSFP mechanical and electrical specifications for interoperability with supporting hardware. It provides simultaneous transmit and receive capability over multimode fiber via the MTP/MPO connector and includes digital diagnostics support where the host system supports DDM/DOM. The product is compact, low-weight and intended for stable, long-term operation in high-density networking environments.

Suitable for

• High-density switch and router uplinks requiring 40 Gigabit Ethernet
• Data center interconnects over multimode fiber up to 300 m
• Storage area networks and aggregation links in campus networks

Key specifications

• Maximum data transfer rate: 40 Mbit/s
• Wavelength: 850 nm
• Maximum transfer distance: up to 300 m (multimode fiber)
• Interface type: QSFP, supports 40 Gigabit Ethernet
• Fiber connector type: MTP/MPO
• Weight: approx. 0.04 kg
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the transceiver into a compatible QSFP slot on a switch, router or other network device that supports QSFP modules. Connect an appropriate MTP/MPO multimode fiber patch cable between transceivers or to a patch panel. Ensure the host device firmware or driver supports 40 Gigabit Ethernet and, if required, DDM/DOM monitoring to access digital diagnostic data. Follow the equipment manufacturer's instructions for hot-plugging, handling ESD-sensitive components and verifying link status after insertion.

Recommendations

Use quality multimode fiber and suitable MTP/MPO patch cords rated for 850 nm to achieve the stated reach of up to 300 m. Verify compatibility with the target hardware and confirm DDM/DOM support if remote diagnostic monitoring is needed.
