Módulo transceptor de fibra ótica BlueOptics QFX-QSFP-40GE-ESR4-BO 40000 Mbit/s 850 nm

The BlueOptics QFX-QSFP-40GE-ESR4-BO is a QSFP fiber optic transceiver module designed for 40 Gbit/s optical links over multimode fiber at a center wavelength of 850 nm. The module features an MPO/MTP connection according to MSA standards and provides simultaneous transmit and receive channels in a compact QSFP form factor. Constructed from high-quality components and tested for use in common networking platforms, it is intended as a compatible alternative for systems that support the corresponding 40GBASE-ESR4 MPO/MTP QSFP module.

Advantages

The transceiver supports a maximum data transfer rate of 40000 Mbit/s and is manufactured to MSA-compatible mechanical and optical specifications to ensure interoperability with network switches, routers and storage systems. It includes Digital Diagnostics Monitoring (DDM/DOM) for real-time monitoring of optical power, supply voltage, laser bias current and temperature, and it is assembled from selected optical and electronic components to provide extended service life and reliability. Its compact QSFP housing and MPO/MTP interface enable high-density, low-latency connections in data centre and enterprise environments.

Suitable for

• 40 Gigabit Ethernet links over multimode fiber in data centres
• High-speed switch-to-switch and switch-to-server interconnects
• Storage area network (SAN) backbones and aggregation links
• System upgrades where MSA-compliant QSFP MPO/MTP transceivers are required

Key specifications

• Interface type: QSFP (MPO/MTP connector)
• Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
• Optical wavelength: 850 nm for transmit and receive
• Compatible fiber: Multimode fiber (MMF)

• Color and weight: silver housing, approx. 0.04 kg
• Digital Diagnostics: DDM/DOM (real-time monitoring of voltage, current, optical power, temperature)
• MSA-compliant mechanical and electrical design for broad hardware compatibility

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on a switch, router or other networking device while the host device is powered down or following the vendor’s hot‑swap instructions. Connect an MPO/MTP multimode fiber patch cable to the transceiver and route the cable to the matching MPO/MTP end or patch panel. After installation, verify link status on the host device and, if supported, consult the DDM/DOM readings to confirm optical power levels and operating temperature. Follow the system vendor’s guidelines for firmware or compatibility settings when integrating into vendor-branded platforms.

Recommendations

Use quality multimode MPO/MTP patch cables and adhere to recommended connector cleaning procedures to maintain signal integrity. Ensure that the host device supports DDM/DOM if you require remote diagnostics. For best performance, match the transceiver to multimode fiber types (OM3/OM4) appropriate for 40GBASE-ESR4 links and observe bend-radius and routing best practices in cabling infrastructure.
