Weighing 40 g, it is lightweight and easy to install.

## Long description

The BlueOptics QSFP-40G-SR4-QL-BO is a QSFP fiber optic transceiver module designed for short-range high-speed optical links. It supports an aggregate data rate of 40 Mbit/s over multimode fiber and uses an 850 nm transmitter and receiver. The module is built in a metal housing, weighs approximately 40 g and offers a high mean time between failures (MTBF) of 1,000,000 hours for continuous operation in compatible network equipment.
Advantages
This QSFP transceiver provides a standardized QSFP electrical and mechanical interface that supports interoperable installation in hardware platforms compatible with the QSFP form factor. The module’s MPO/MTP-compatible optical interface and 850 nm optics are suitable for multimode fiber links, while the durable metal casing and the tested MTBF rating contribute to reliable long-term operation. Digital diagnostic monitoring (DDM/DOM) support is typically available on modules of this design to facilitate remote monitoring of operational parameters when the host hardware provides the required support.
Suitable for
 Short-range 40G multimode fiber connections in data center aggregation and top-of-rack links
 Interconnection between switches, routers and storage systems that accept QSFP modules
 High-speed Ethernet and Fibre Channel over Ethernet applications on multimode fiber

How to use
Install the BlueOptics QSFP-40G-SR4-QL-BO into a compatible QSFP slot on a switch, router or storage device while the host system is powered according to the hardware vendor’s instructions. Connect multimode MPO/MTP patch cords to the module and route them to the corresponding transceiver or patch panel. Ensure the host platform supports the QSFP module and, if needed, enable any required firmware or software compatibility features. Verify link status and diagnostics through the host management interface after installation.
Usage recommendations
Use high-quality multimode MPO/MTP patch cords and maintain proper fiber cleanliness to achieve optimal signal quality. Confirm that the network hardware supports the module’s diagnostic functions to take advantage of DDM/DOM monitoring; if diagnostics are required, verify compatibility with the host platform before deployment.
