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

The BlueOptics QSFP-40G-ESR4-IA-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s data transmission over multi-mode fiber. It operates at an 850 nm wavelength, uses an MPO/MTP connector and supports distances up to 300 m. The module is lightweight (0.04 kg) and conforms to QSFP MSA mechanical and electrical standards to ensure interoperability with compatible 40 Gigabit Ethernet hardware. With a rated MTBF of 1,000,000 hours, it is intended for continuous operation in data centers and high-performance networking environments.

Advantages

This QSFP transceiver combines a standardized QSFP interface, MPO/MTP connectivity and support for 40 Gigabit Ethernet to simplify installation and integration into existing fiber infrastructures. The module provides simultaneous transmit and receive functionality on multi-mode fiber at 850 nm and is tested for compatibility with hardware that supports the corresponding 40GBASE-ESR4 protocol. The compact, lightweight design reduces rack space and handling complexity while the specified MTBF indicates a long operational life for reduced maintenance cycles.

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch, router or optical device following the host equipment manufacturer’s hot-swap and handling guidelines. Connect MPO/MTP multi-fiber patch cables to the module and ensure correct polarity and fiber type (multi-mode) for 850 nm operation. Verify link status and configure the host port for 40G operation as required by your network equipment. If supported, enable or monitor Digital Diagnostic Monitoring (DDM/DOM) features through the host to track supply voltage, optical power and temperature in real time.

Recommendations

Use high-quality MPO/MTP patch cords and maintain proper fiber cleanliness to achieve optimal signal quality and the specified 300 m reach. Confirm compatibility and firmware requirements with the switch or router vendor before deployment and, when possible, perform a test installation to validate link performance and DDM/DOM reporting.
