BlueOptics K2Q21A-BL InfiniBand kuitu-kaapeli 3 m SFP+ pistoke/pistoke

The BlueOptics K2Q21A-BL InfiniBand Fibre Optic Cable 3 m SFP+ Male/Male is a 3-meter high-speed direct attach cable with SFP+ connectors designed for short-range data links. It provides a male-to-male SFP+ interface for direct connectivity between compatible network devices and supports InfiniBand and 10G-class data transfer applications where SFP+ transceivers and ports are used. The cable is intended for reliable rack-to-rack or within-rack connections in data centers and network equipment rooms.

Advantages

The cable offers a compact, passive direct-attach format that simplifies short-distance interconnections without additional transceiver modules. The SFP+ male-to-male connectivity ensures straightforward installation into SFP+ ports and reduces the need for separate optical transceivers. Manufactured to align with industry MSA standards, the product is suitable for environments that require consistent 10G-class performance and interoperability with hardware that supports the corresponding direct-attach form factor and signaling.

Suitable for

• Short-range rack-to-rack connections in data centers
• Direct links between switches, routers and storage systems with SFP+ ports
• InfiniBand and 10G Ethernet/FCoE interfaces on supported hardware

Key specifications

• Cable type: Direct attach / twinax-style direct connection with SFP+ male connectors
• Length: 3 m
• Connector type: SFP+ male to SFP+ male
• Supported protocols: InfiniBand and 10G-class data applications (Ethernet, FCoE, Fibre Channel where supported)
• Form factor: Passive direct-attach cable for short-distance interconnects

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the two devices to be linked, ensuring the latches engage and the connectors are fully seated. Use the cable for short-distance links within racks or between adjacent racks, taking care to route the cable without tight bends and to avoid placing it under mechanical strain. Confirm that the connected hardware supports passive direct-attach twinax cabling and that firmware or vendor compatibility requirements are met before placing the link into production.

Recommendations

For reliable operation, verify device compatibility with SFP+ passive direct-attach cables and follow rack-cabling best practices: avoid sharp bends, maintain adequate airflow around equipment, and label both ends of the cable. If vendor compatibility or firmware restrictions exist, consult the hardware manufacturer’s documentation or request a test sample prior to deployment.
