InfiniBand/fibre optic cable Cisco STACK-T4-3M= Black Grey 3m

The Cisco STACK-T4-3M= is an InfiniBand/fibre optic cable designed for high-speed data connections in networking and data centre environments. With a 3 meter length and a two-tone black and grey jacket, the cable provides a balance of flexibility and mechanical protection. It is intended for use with compatible Cisco stacking ports and high-performance interconnects where reliable signal integrity and low-latency transmission are required.

Advantages

The cable combines fibre optic transmission characteristics with a construction suited to rack and data centre use, offering consistent throughput and resistance to electromagnetic interference. Its 3 m length allows for convenient device placement without excessive slack. The reinforced jacket improves abrasion resistance while maintaining manageable bend radius for common installation paths. The product is built to meet the mechanical and optical tolerances expected for enterprise networking equipment.

Suitable for

• Connecting Cisco switches and stackable devices across racks or within a single rack
• High-bandwidth, low-latency links in data centre topologies
• Interconnects between servers and storage appliances using InfiniBand or fibre channels
• Replacement or upgrade of existing fibre optic links in enterprise networks

Key specifications

• Cable type: InfiniBand / fibre optic multimode-compatible construction
• Length: 3 metres
• Outer jacket colour: black and grey
• Connector interfaces: industry-standard fibre/InfiniBand style connectors for Cisco stacking ports
• Designed for: high-speed, low-latency data transmission in professional networking environments
• Mechanical properties: flexible jacket with controlled bend radius and abrasion resistance

How to use

Ensure both endpoints are powered down or follow hot-swap procedures recommended by the device manufacturer before making the physical connection. Route the cable through rack channels or cable management trays keeping the bend radius within recommended limits. Insert the connectors fully into the corresponding Cisco stacking or InfiniBand ports until a positive engagement is felt. After connection, verify link status and speeds via the device management interface and test data throughput to confirm proper operation.

Usage recommendations

Handle the cable by the connector boots when routing to avoid stressing the fibre. Maintain bend radii greater than the minimum specified by the equipment vendor and avoid sharp edges or kinks. For critical links, periodically inspect the jacket for damage and verify optical performance during maintenance windows.
