InfiniBand/fibre optic cable BlueOptics 487649-B21 1 m SFP+ Male/Male

The BlueOptics 487649-B21 1 m InfiniBand/fibre optic cable with SFP+ male-to-male connectors provides a single-mode optical link for high-speed data transmission. Designed for rack and data centre environments, this 1 metre cable supports reliable connectivity between SFP+ ports on switches, servers and host adapters. The cable’s construction and SFP+ form-factor ensure low latency and signal integrity across short server-to-switch and switch-to-switch links.

Advantages

This SFP+ male/male fibre optic cable delivers stable high-bandwidth performance with minimal signal loss over the 1 m length, suitable for demanding networking tasks. It is engineered for compatibility with standard SFP+ ports and offers a compact, flexible design that simplifies routing in dense cable environments. The BlueOptics cable emphasizes consistent transmission quality and easy installation without additional transceiver modules.

Suitable for

• Short-reach connections between servers and switches in data centres
• High-speed links for InfiniBand and Ethernet SFP+ ports
• Interconnects in rack-mounted networking equipment
• Upgrading existing SFP+ infrastructure for reliable fibre connections

Key specifications

• Length: 1 metre
• Connector type: SFP+ male to SFP+ male
• Media: fibre optic (single-mode compatible for SFP+ use)
• Intended use: InfiniBand and SFP+ Ethernet links
• Colour: blue

How to use

Ensure both devices support SFP+ optical interfaces and are powered down or in maintenance mode if required by your equipment procedures. Align each SFP+ connector with the corresponding port and insert until it clicks or seats firmly. Verify link status on connected devices and confirm speed and duplex settings if applicable. For removal, depress the latch or release mechanism and gently withdraw the connector to avoid stressing the fibre.

Recommendations

Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius; keep connectors clean and protected from dust when not in use. Use appropriate inventory labelling and document link endpoints to simplify maintenance and troubleshooting in clustered or dense rack deployments.
