QSFP transceiver BlueOptics QSFP-40G-SR4-NG-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-NG-BO is a QSFP fiber optic transceiver module designed for short-range multimode links. It supports a maximum data rate of 40 Mbit/s at an 850 nm wavelength and uses an MPO/MTP interface for simultaneous transmit and receive across multiple fibers. The module comes in a metal housing, weighs 20 g, and is specified with an MTBF of 1,000,000 hours for long-term operation in network equipment that follows QSFP MSA mechanical and electrical standards.

Advantages

The transceiver provides compatibility with QSFP ports that accept 40GBASE-SR4 interfaces and supports multimode fiber applications. Its metal housing offers mechanical durability while the lightweight design simplifies handling and installation. Built-in digital diagnostics (where supported by host hardware) enable real-time monitoring of supply voltage, laser current, optical output and input power, and temperature to assist with remote maintenance and troubleshooting.

Suitable for

• High-speed short-range links in data center switches and routers
• Server interconnects and storage area network uplinks
• Aggregation and spine-leaf topologies using multimode fiber
• Environments requiring QSFP MSA-compatible pluggable optics

• Maximum data transfer rate: 40 Mbit/s
• Optical wavelength: 850 nm
• Fiber type: Multimode fiber (MMF), 40GBASE-SR4 application
• Housing: Metal
• Weight: 0.02 kg
• MTBF: 1,000,000 hours

How to use

Install the transceiver into a compatible QSFP port according to the host device manufacturer’s instructions. Use an MPO/MTP multimode patch cord or appropriate breakout assemblies to connect to other QSFP transceivers or patch panels. Ensure the host hardware supports 40GBASE-SR4 operation and, if monitoring is required, that the device exposes Digital Diagnostics (DDM/DOM) data. Observe standard electrostatic discharge (ESD) precautions and keep the optical connectors covered until ready for connection.

Recommendations

For optimal performance, pair the module with high-quality multimode fiber and certified MPO/MTP patch cords, verify link budget for the intended cable length, and confirm that the host switch or router firmware supports third-party QSFP modules and DDM. Regularly inspect connector end faces and follow ESD and handling guidelines to maintain signal integrity.
