## Long description

The BlueOptics ET7402-AOC-25M-BO InfiniBand fibre optic cable 25m QSFP28 Male/Male is a 25-metre active optical cable (AOC) with QSFP28 connectors on both ends. Designed for high-speed data transmission over multimode fiber, this AOC implements the QSFP28 to QSFP28 connection according to MSA standards and supports 100GBASE-SR4 applications. The cable integrates optical transmitter and receiver modules on each end to transfer optical signals and is intended for use in data center and high-performance computing environments where reliable 100 Gbit/s links are required.
Advantages
This 25 m AOC provides a factory-terminated, plug-and-play QSFP28 to QSFP28 solution that eliminates the need for separate transceivers and patch cords, simplifying installation and reducing potential points of failure. Compliance with MSA standards ensures interoperability with equipment that supports QSFP28 and 100GBASE-SR4 interfaces. The male-to-male QSFP28 configuration offers broad compatibility with switches, routers and storage systems that accept QSFP28 AOCs for short-reach 100G connections.
Suitable for
 Data center uplinks and switch-to-switch connections
 High-performance computing clusters and interconnect fabrics
 Storage area networks and server-to-switch links requiring 100G
 Short-reach InfiniBand and Ethernet 100GBASE-SR4 links up to 25 m
Key specifications
 Length: 25 metres
 Connector type: QSFP28 Male to QSFP28 Male
 Media: Active Optical Cable using multimode fiber
 Supported interface: 100GBASE-SR4 and compatible 100 Gbit/s protocols
 Integrated transmitter and receiver modules on both ends
 Designed for short-reach, high-bandwidth interconnects
How to use
Install the BlueOptics ET7402-AOC-25M-BO by inserting the QSFP28 connectors into compatible QSFP28 ports on network switches, routers or host devices. Ensure devices are powered off or follow hot-plug guidelines provided by the hardware vendor when plugging in or removing the cable. Verify link status and data rate through the device management interface and confirm compatibility with the host ports' supported protocols such as 100GBASE-SR4. No separate optics or additional patch cords are required.
Usage recommendations
Use in indoor data center environments with organized cable routing and strain relief; avoid tight bends and exposure to excessive mechanical stress. Confirm equipment compatibility with QSFP28 AOCs and the supported 100G protocol before deployment. For diagnostic or interoperability assurance, test the link under expected load conditions in a controlled environment prior to full production use.
