## Summary description

The BlueOptics QSFP-40G-SR4-AR-BO is a fiber optic transceiver module designed for high-speed data transfer at 40 Mbit/s. It operates at a wavelength of 850 nm and features a QSFP interface. With a robust metal housing and a long MTBF of 1,000,000 hours, it ensures reliability in network applications. The module requires a 3.3 V input voltage and weighs only 20 g, making it an efficient choice for data centers.

## Long description

The BlueOptics QSFP-40G-SR4-AR-BO is a QSFP fiber optic transceiver module for 40 Mbit/s multimode optical links. It operates at a nominal wavelength of 850 nm, uses an MPO/MTP connector and is designed for insertion into QSFP ports on compatible network equipment. The module has a robust metal housing, requires a 3.3 V input supply and has a documented mean time between failures (MTBF) of 1,000,000 hours, making it suitable for continuous operation in dense networking environments. Weighing 20 g, the transceiver provides a compact, hot-pluggable solution for short-range 40 Mbit/s optical connections.
Advantages
The transceiver supports standardized QSFP form-factor interoperability and follows MSA-compatible mechanical and electrical specifications for consistent fit and function in QSFP ports. Its metal housing offers mechanical protection and thermal stability while the long MTBF indicates a design intended for extended service life. With an 850 nm transmitter/receiver pair optimized for multimode fiber and an MPO/MTP interface, the module enables simultaneous transmission and reception over compatible multimode cabling.
Suitable for
 Short-range multimode fiber links in data centers and server rooms
 40 Mbit/s Ethernet and other high-speed optical interconnects over multimode fiber
 Interconnection between switches, routers, storage systems and optical patch panels using MPO/MTP
Key specifications

How to use
Install the module by hot-plugging it into a compatible QSFP port on network equipment that supports the corresponding QSFP transceiver specification. Ensure the host device supports DDM/DOM functionality if real-time diagnostic monitoring is required. Connect multimode MPO/MTP patch cords to the module and verify link status via the host system. Observe proper handling procedures for optical transceivers: avoid touching the connector endface, keep protective caps in place when not connected, and follow electrostatic discharge (ESD) precautions during installation.
Usage recommendations
Use short-range multimode fiber rated for 850 nm and MPO/MTP assemblies tested for compatibility to achieve the specified performance. Confirm that the network hardware firmware or OS accepts MSA-compatible third-party QSFP modules and that DDM/DOM support is enabled on the host when diagnostic monitoring is needed.
