InfiniBand/optický kábel BlueOptics DEM-CB300QXS 3 m QSFP konektor samec/konektor samec

The BlueOptics DEM-CB300QXS 3 m QSFP Male/Male cable is a fibre optic and InfiniBand-compatible assembly designed for high-speed interconnects in data centre and enterprise networking environments. With a 3-metre length and QSFP male connectors at both ends, this cable supports short-range, low-latency links between switches, HCAs (Host Channel Adapters), and network appliances. The cable is intended for applications requiring predictable signal integrity and consistent throughput.

Advantages

This QSFP-to-QSFP cable delivers high data rates suitable for InfiniBand and fibre optic infrastructures while maintaining a compact and flexible form factor for rack and chassis installations. Its male/male QSFP connectors ensure straightforward mating with standard QSFP ports, and the fixed 3 m length reduces clutter compared with longer, unmanaged assemblies. The design focuses on stable connectivity and minimal insertion loss to support reliable performance in dense networking setups.

Key specifications

How to use

Install the cable by aligning each QSFP male connector with the corresponding QSFP port on your devices and gently inserting until the connector seats. Verify link status through device LEDs or management interfaces to confirm successful negotiation. Avoid bending the cable sharply near the connector ends; route it along cable management paths in racks or chassis to prevent strain. For safe removal, depress any latching mechanism on the connector and pull straight out to avoid damaging ports.

Recommendations

Use the cable for short-reach links within the same rack or adjacent racks to maintain performance and reduce latency. Keep the cable in environments within manufacturer-recommended temperature and humidity ranges, and avoid exposing it to mechanical stress. When replacing or upgrading QSFP links, confirm compatibility with your devices' QSFP interface specifications and link speed settings.
