Cabo de fibra ótica InfiniBand BlueOptics 487655-B21-BL 3 m SFP+ macho/macho

The BlueOptics 487655-B21-BL is a 3 m InfiniBand/fibre optic cable with SFP+ male connectors on both ends, designed for high-speed data transfer in data centre and enterprise network environments. Its 3-metre length provides a balance between reach and cable management, enabling connections between switches, servers and storage devices while maintaining signal integrity. The cable construction focuses on reliable optical performance and mechanical durability suitable for rack and cabinet installations.

Advantages

This fibre optic cable supports SFP+ interfaces for high-bandwidth links, reducing latency and preserving signal quality over the specified distance. The male-to-male connector configuration ensures straightforward plug-and-play compatibility with SFP+ transceivers and ports. The 3 m length offers flexibility for common rack layouts without excessive slack, and the cable jacket is designed to withstand routine handling and routing in networking closets.

Suitable for

• Connecting SFP+ ports between switches and routers
• Server-to-switch connections in data centres
• High-speed links for storage area networks (SAN)
• Short- to medium-reach InfiniBand or optical interconnects

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 3 m
• Cable type: InfiniBand / fibre optic
• Typical application: High-speed data links in rack environments
• Construction: Durable jacket suitable for cable routing and rack installation

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on network devices, ensuring the connectors are properly seated and any retention mechanisms are engaged. Route the cable along cable management paths to avoid sharp bends and excessive tension; maintain the minimum bend radius recommended for fibre optic cables. Verify link status on connected devices and, if required, confirm transceiver compatibility and port configuration in device management interfaces.

Recommendations

For optimal performance, avoid tight bends and protect connector end-faces from dust and contaminants. Use dust caps when the cable is not connected and inspect connector ferrules before insertion. When deploying in dense rack setups, plan cable paths to minimize strain and maintain airflow.
