## Long description

The BlueOptics QSFP-4X25G-C3M-BL InfiniBand fibre optic cable is a 3 m QSFP28 male-to-male connection designed for high-speed links in data centers and high-performance computing environments. It provides a direct, low-latency connection for short-reach interconnects between QSFP28 ports and supports multi-protocol use including Ethernet and InfiniBand where QSFP28 connectivity is required.
Advantages
This 3 m QSFP28 cable offers a compact male-to-male connection that is suitable for rack-to-rack or within-rack short-distance links. The design ensures low latency and reliable signal integrity for high-throughput applications. Manufactured to industry mechanical and form-factor standards, it is intended for straightforward installation and predictable physical behaviour in dense cabling environments.
Suitable for
 Short-reach connections between QSFP28 ports in switches, routers and storage systems
 High-performance computing clusters and InfiniBand fabrics
 Data centre rack and adjacent-rack interconnects up to 3 m
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Cable length: 3 metres
 Intended use: short-reach, high-speed interconnects for InfiniBand and compatible Ethernet applications
 Form factor: QSFP28 direct attach-style connection for 100G-class links
How to use
Connect each QSFP28 plug to the corresponding QSFP28 port on the devices to be linked, ensuring proper seating and latch engagement. Use this cable for short-distance links — typically within the same rack or to adjacent racks — and verify that the host hardware supports passive direct-attach QSFP28 connections or InfiniBand QSFP28 transceiver interfaces as required by your system firmware and software. Follow standard electrostatic discharge (ESD) precautions when handling connectors.
Usage recommendations
Verify compatibility with your switch, router or host platform prior to deployment and consult device documentation for supported port modes and cable types. Route the cable to avoid tight bends and mechanical strain; maintain manufacturer-recommended bend radii and secure cable paths to prevent connector stress.
