InfiniBand/optický kabel SFP+ SFP+ DAC černý BlueOptics CBL-10GSFP-DAC-4M-BL 4 m samec/samec

The BlueOptics CBL-10GSFP-DAC-4M-BL is a 4 m direct-attach InfiniBand/fibre optic cable with SFP+ male connectors at both ends. Designed for high-speed networking links, this cable supports reliable short-reach data transmission between compatible SFP+ ports in switches, servers and storage devices. Its 4 metre length provides flexibility for rack-to-rack or within-rack connections while maintaining signal integrity for 10 Gbps class links.

Advantages

This SFP+ to SFP+ direct-attach cable offers low latency and consistent performance for short distance interconnects. The pre-terminated male/male configuration simplifies installation by avoiding separate transceivers, and the black sheath with blue identification marking helps organize cabling runs. The construction is optimized for stable electrical characteristics and reduced signal loss over the specified 4 m range.

Suitable for

• 10 Gbps server-to-switch connections in data centres
• Inter-switch links and top-of-rack networking
• Storage area network (SAN) short-reach links
• High-performance computing and InfiniBand environments requiring SFP+ ports

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 4 metres
• Designed for: InfiniBand and fibre optic SFP+ interfaces
• Data rate class: suitable for 10 Gbps systems
• Jacket colour: black with blue identification

How to use

Ensure both devices have compatible SFP+ ports and that power to network equipment is handled according to your operational procedures. Insert each SFP+ connector into the corresponding port until it seats firmly and the latch engages. Avoid sharp bends in the cable and route it to minimize stress and interference. After installation, verify link status on both devices and confirm negotiated speeds and health through device management interfaces.

Recommendations

For reliable performance, use this 4 m SFP+ direct-attach cable for short-reach connections only and avoid extending beyond intended distances. Maintain minimum bend radius, keep connectors clean and handle the cable by the connector boots during insertion and removal. Store spare cables in a dry, dust-free environment to preserve connector quality.
