Glasvezel-transceivermodule BlueOptics FA-40GB-ETH-SFP-SR-BO QSFP MPO MTP

The BlueOptics FA-40GB-ETH-SFP-SR-BO is a 40GBASE-SR4 compatible fiber optic transceiver module with a QSFP interface and MPO/MTP connector designed for high-speed multimode fiber links. It supports parallel optical transmission using 850 nm lasers for transmit and receive channels, offering up to 40 Gbit/s aggregate data throughput over short-range multimode fiber. The module is lightweight (approx. 20 g) and anodised aluminium in colour, suitable for installation in QSFP ports on switches, routers and storage systems that accept QSFP 40GBASE-SR4 modules.

Advantages

This transceiver implements the QSFP form factor and MPO/MTP connectivity according to MSA standards, enabling interoperable connections with compatible multimode fiber cabling. It supports Digital Diagnostics Monitoring (DDM/DOM) for real-time information on supply voltage, laser bias current, transmit power, receive power and temperature where the host supports these features. The module is designed for consistent performance over typical multimode distances for SR4 optics and is constructed from industry-grade components to provide stable operation and long service life.

Suitable for

• 40 Gigabit Ethernet links over multimode fiber in data centre aggregation and spine/leaf networks
• High-speed interconnects between switches, routers and storage arrays
• Short-range Fibre Channel over Ethernet (FCoE) or SDH/SONET applications requiring 40 Gbit/s
• Patch-panel to transceiver MPO/MTP connections in campus and enterprise networks

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Wavelength: 850 nm transmit and receive
• Connector type: MPO / MTP multimode fiber connector
• Supported protocol: 40GBASE-SR4 Ethernet (also usable for equivalent Fibre Channel/SDH links)
• Fiber type: Multimode fiber (MMF)
• Typical maximum link distance: typical SR4 multimode range (dependent on fiber type and cabling)
• Weight: approximately 0.02 kg
• Colour / housing: aluminium
• Digital diagnostics: DDM/DOM support (if host hardware provides access)

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port until it seats and latches according to the host device instructions. Connect an MPO/MTP multimode patch cable to the transceiver and to the corresponding MPO/MTP breakout or module on the opposite end. Ensure the host device is configured for 40GBASE-SR4 operation and that any required firmware or port settings permit use of third-party transceivers. If monitoring is needed, enable DDM/DOM access in the host to read real-time diagnostic parameters.

Recommendations

Use appropriate OM3/OM4 multimode fiber cabling and MPO/MTP patch cords to achieve expected SR4 distances. Verify compatibility with the host device and maintain clean connector end-faces to reduce optical loss. For critical links, confirm DDM/DOM reporting is available on the installed platform and monitor optical power and temperature values during commissioning.
