## Summary description

The BlueOptics QSFP-40G-SR4-NG-BO is a fiber optic transceiver module designed for high-speed data transfer. It supports a maximum data rate of 40 Mbit/s and operates at a wavelength of 850 nm. The metal housing ensures durability, while the lightweight design (20 g) makes it easy to install. With a mean time between failures (MTBF) of 1,000,000 hours, it offers reliable performance for network applications.

## Long description

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
Key specifications
Interface type: QSFP with MPO/MTP optical connector
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.
Usage 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.
