## Long description

The BlueOptics 40G-QSFP-SR4-INT-EN-BO is a metal QSFP fiber-optic transceiver designed for short-reach multimode links. It provides a QSFP interface, supports a maximum data transfer rate of 40 Mbit/s and operates at a wavelength of 918 nm. The module requires a 3.3 V input voltage, has a mean time between failures (MTBF) of 1,000,000 hours and weighs approximately 20 g, making it a compact option for high-density network environments.
Advantages
This transceiver is constructed with a metal housing for mechanical stability and thermal dissipation. Its QSFP interface allows efficient aggregation and high-density port configurations. With an MTBF of 1,000,000 hours and the use of high-quality components, the module is intended to deliver long operational life and reduced maintenance cycles. The compact weight and standard electrical requirements make the unit easy to integrate into existing networking hardware that supports QSFP form-factor modules.
Suitable for
Short-reach multimode fiber connections in data center uplinks and switch interconnects
High-density network equipment with QSFP ports
Applications requiring compact, metal-housed pluggable optics
