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

The BlueOptics QSFP-40G-ESR4-MT-BO is a compact QSFP fiber optic transceiver module designed for 40 Mbit/s high-speed optical links. Operating at an 850 nm wavelength with an MTP/MPO connector, the module supports multimode fiber transmission over distances up to 300 m. With a lightweight 40 g housing and an MTBF of 1,000,000 hours, this transceiver is intended for integration into network switches, routers, storage systems and other 40 Gigabit Ethernet platforms that accept QSFP form-factor optics.

Advantages

This BlueOptics QSFP transceiver provides standardized MSA-compliant electrical and mechanical interfaces for broad interoperability and straightforward integration. The 850 nm transmitter and receiver are optimized for multimode fiber, delivering low-latency simultaneous send/receive capability via MPO/MTP connections. Designed with quality components and tested for compatibility, the module offers a long operational life and digital diagnostics support for remote monitoring when the host hardware supports DDM/DOM.

Suitable for

• 40 Gigabit Ethernet uplinks and high-speed server interconnects
• Switch-to-switch and router-to-router optical links within data centers
• Storage area network (SAN) connectivity and high-throughput applications
• Short-reach multimode fiber runs up to 300 m in enterprise and campus networks

Key specifications

• Data rate: 40 Mbit/s
• Wavelength: 850 nm (transmit and receive)
• Maximum transfer distance: 300 m (multimode fiber)
• Connector type: MTP/MPO
• Interface: 40 Gigabit Ethernet (QSFP form factor)
• Weight: 0.04 kg
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the QSFP transceiver into a compatible QSFP slot on a switch, router or other network device following the host manufacturer's hot-plugging and electrostatic discharge (ESD) handling guidelines. Connect an appropriate MTP/MPO multimode fiber patch cord between transceivers or to a patch panel. Verify link parameters in the host device management interface and, if available, enable or read Digital Diagnostic Monitoring (DDM/DOM) to monitor supply voltage, laser bias current, optical output and input power, and module temperature.

Recommendations

For reliable short-reach operation, use high-quality OM3/OM4 multimode fiber and certified MTP/MPO patch cords, ensure proper connector cleaning before mating, and confirm host hardware compatibility with QSFP-40G multimode modules and DDM/DOM features. Follow vendor guidelines for temperature and handling to maintain the specified MTBF and transmission performance.
