## Summary description

The BlueOptics QSFP-H40G-CU1M is a 1 m InfiniBand fibre optic cable designed for high-speed data transfer. It features QSFP connectors on both ends, ensuring reliable connectivity for data centers and networking applications. The cable is ideal for connecting switches, routers, and servers in high-performance computing environments.

## Long description

The BlueOptics QSFP-H40G-CU1M InfiniBand fibre optic cable is a 1 m direct-attach cable engineered for short-range, high-bandwidth interconnects. With QSFP (Quad Small Form-factor Pluggable) connectors on both ends, the cable supports InfiniBand protocols and is suited to dense networking racks and high-performance computing clusters where reliable, low-latency data paths are required. The black jacket provides a durable outer layer appropriate for data centre and cabling-closet environments.
Advantages
This 1 m InfiniBand cable offers a compact, low-latency connection with straightforward installation. The QSFP-to-QSFP termination ensures connector compatibility with QSFP ports used in modern switches, routers and servers, reducing the need for additional transceivers. The construction emphasises signal integrity for short-reach links and a jacket designed for frequent handling and routing in structured cabling setups.
Suitable for
Connecting switches and routers with QSFP ports in data centres
Short-range links between servers in compute clusters
High-performance computing and InfiniBand fabric interconnects
Rack-to-rack or shelf-to-shelf connections within the same cabinet
Key specifications
Connector type: QSFP on both ends
Cable length: 1 metre
Colour: Black outer jacket
Intended use: Short-range, high-bandwidth InfiniBand data links
Application environment: Data centres, server rooms, high-performance computing
How to use
Ensure both devices support QSFP InfiniBand ports and power down or follow hot-plug procedures recommended by the hardware vendor. Route the cable through rack channels or cable management to avoid sharp bends; the 1 m length is suited for close-proximity connections. Insert each QSFP connector firmly into its port until the latch engages and verify link status in the switch or host interface. If required by the system, configure interface parameters or fabric settings through the networking equipment management interface.
Usage recommendations
For reliable signal performance, avoid bending the cable beyond the manufacturer’s minimum bend radius and minimize exposure to mechanical strain. Use the 1 m length for short, direct connections; for longer distances select an appropriate alternative. Maintain cleanliness of QSFP connectors and follow equipment vendor guidance for hot-plug operations and firmware compatibility when deploying in production environments.
