## Long description

The BlueOptics QSFP-40G-C5M-BL InfiniBand Fibre Optic Cable 5 m Male/Male is a 5-metre high-speed connection solution with QSFP connectors on both ends designed for InfiniBand and other 40G applications. It provides a direct attach link intended for short-range rack-to-rack or within-rack connections in data centre and networking environments where a 40 Gbit/s link is required. The cable is presented as compatible with common hardware platforms that support QSFP 40G connections and is intended for use where reliable, low-latency data transfer is necessary.
Advantages
The cable offers a 5 m length with QSFP-to-QSFP connectivity to support data rates up to 40 Gbit/s on short distances. It is designed to meet MSA-compliant mechanical and electrical characteristics for QSFP-based direct attach connections and is suitable for use with switches, routers and storage systems that support QSFP 40G links. The construction uses industry-standard components intended to provide long service life and consistent performance for professional networking installations.
Suitable for
High-speed rack-to-rack connections in data centres
Short-distance links between switches, routers and storage systems
InfiniBand, Ethernet and other 40G transport applications (where hardware supports 40G DAC)
Key specifications
Cable type: QSFP to QSFP direct attach (passive twinax style for short-range 40G links)
Length: 5 metres
Data rate support: up to 40 Gbit/s
Connector gender: male to male (QSFP on both ends)

How to use
Install the cable by inserting each QSFP male connector into the corresponding QSFP port on the network devices, ensuring that both devices support passive 40G direct attach connections. Route the cable within racks or between adjacent racks avoiding tight bends and excessive tension. After insertion, verify link status on connected hardware and confirm negotiated speed and protocol support in device management interfaces. Remove the cable by unlatching the QSFP connector latch mechanism before pulling the cable from the port.
