## Long description

The Cisco QSFP-100G-CU5M= is a 5-meter InfiniBand/fibre optic cable with QSFP28 connectors on both ends, designed for high-speed data transmission. This male-to-male cable supports 100G Ethernet and InfiniBand applications, providing a direct-attach connection for short- to medium-reach links in data centers and high-performance computing environments. The cable is finished in grey and fits QSFP28 ports for low-latency, high-throughput links between switches, servers and storage interfaces.
Advantages
The cable provides a single-cable solution for 100G Ethernet and InfiniBand-compatible ports, enabling straightforward, low-latency links without the need for additional transceivers. Its QSFP28 connector compatibility simplifies installation and reduces the number of components in the link. The 5 m length allows flexible rack-to-rack or within-rack connections while maintaining signal integrity suitable for short- to medium-distance high-bandwidth applications.
Suitable for
Interconnects between switches and routers in data centers
Server-to-switch connections in high-performance computing clusters
Storage array connections requiring 100G throughput
Short-distance InfiniBand links for low-latency applications
Key specifications
Connector type: QSFP28 to QSFP28 (male-to-male)
Length: 5 meters
Supported protocols: 100G Ethernet and InfiniBand-compatible signaling
Typical use case: Direct-attach cable for short- to medium-reach high-bandwidth links
Cable colour: Grey
Designed for low latency and high throughput
How to use
Install the cable by firmly inserting each QSFP28 connector into the respective QSFP28 ports on devices such as switches, servers or storage systems. Ensure ports are powered down or follow vendor hot-plug guidelines if applicable. Verify link status in device management software or network monitoring tools and confirm negotiated speed and protocol. Route the cable to avoid sharp bends and minimize electromagnetic interference; secure with cable management accessories as needed.
Usage recommendations
For reliable operation, use this cable within recommended bend radius limits and avoid tight kinks. Reserve it for short- to medium-reach connections where direct-attach cabling is supported by both endpoints. Check device compatibility for QSFP28 direct-attach copper/fibre assemblies and confirm firmware/network settings to ensure full 100G link negotiation.
