Fiber optic stack cable Cisco STACK-T4-50CM=, 0.5 m length, InfiniBand/fibre, black/grey

Cisco STACK-T4-50CM= is a 0.5 m fiber optic stack cable engineered for InfiniBand and fibre connectivity between compatible Cisco switches and devices. The short-length design provides a stable optical connection for stacking or high-speed interconnects in rack environments. The cable features black/grey jacketing for discreet routing and improved cable management in data centers and network closets.

Advantages

The cable offers low-latency optical linking suitable for short-distance stacking applications, maintaining signal integrity for high-throughput environments. Its compact 0.5 m length reduces excess cabling in dense rack deployments and simplifies airflow and cable routing. The black/grey outer jacket provides a neutral appearance and abrasion resistance appropriate for professional installations.

Suitable for

• Stacking compatible Cisco switches in the same rack or adjacent racks
• Short-distance InfiniBand or fibre interconnects requiring optical links
• Data center and network closet installations where cable length control and tidy routing are important

Key specifications

• Cable type: fiber optic stack cable for InfiniBand/fibre use
• Length: 0.5 m (50 cm)
• Jacket colour: black/grey
• Connector style: designed for stacking ports on compatible Cisco devices
• Intended use: short-range optical stacking and high-speed interconnects

How to use

Inspect both device stack ports to ensure they are compatible and free from dust or debris. Align the cable connectors with the stacking ports on each Cisco device and insert until seated according to the device manufacturer’s guidance. Route the cable to avoid sharp bends and to maintain proper bend radius for fiber optic cabling. Verify link status on each device to confirm an active optical connection before completing rack installation.

Recommendations

Use in controlled rack environments and avoid excessive bending, crushing, or exposure to liquids. For optimal performance, clean fiber connectors with appropriate fiber cleaning tools before mating and follow Cisco device documentation for stacking procedures and link validation.
