Network Cable BlueOptics CAB-STK-E-3M Stacking Cable RJ45 Ethernet 3 Meter Blue

The BlueOptics CAB-STK-E-3M Stacking Cable RJ45 Ethernet 3 Meter Blue is a 3-meter network cable designed for stacking network switches and establishing reliable high-speed Ethernet links. Featuring standard RJ45 connectors and construction that meets Ethernet cabling requirements, the cable delivers consistent data transfer for local networks. Its blue sheath and durable jacket make it suitable for visible installations and repeated handling, while the 3 m length provides flexibility for rack and cabinet layouts.

Advantages

The cable offers stable high-speed data transfer and compatibility with devices using standard RJ45 Ethernet ports. Mechanical robustness in the jacket and connectors helps maintain connection integrity during frequent reconfiguration. The 3 meter length balances reach and tidy cable management in racks, cabinets or between adjacent equipment. Conformance to Ethernet wiring standards ensures predictable signal performance and interoperability with common network hardware.

Suitable for

• Stacking switches in server rooms and network racks
• Connecting adjacent networking devices in data cabinets
• Short to medium reach Ethernet links in office and server environments
• Visible installations where cable color coding assists organization

Key specifications

• Cable length: 3 meters
• Connector type: RJ45 on both ends
• Designed use: stacking and short-range Ethernet connections
• Sheath color: blue
• Construction: stranded/solid conductor appropriate for Ethernet signaling (category-rated per manufacturer specification)

How to use

Insert the RJ45 connector firmly into the corresponding Ethernet port of each device until the latch clicks. Route the 3 m cable to avoid sharp bends and excessive tensile stress; leave service loops if frequent movement is expected. For stacked switch installations, connect the designated stacking or Ethernet ports on each switch according to the switch vendor's stacking diagram. Ensure both ends are fully seated and verify link status LEDs on devices to confirm a successful connection.

Usage recommendations

For best performance, avoid running the cable alongside high-voltage power lines and keep bend radius above the manufacturer's minimum. Use cable management accessories (ties, clips, Velcro) to secure the cable in racks and prevent strain on RJ45 connectors. Confirm device port speed and duplex settings when troubleshooting link issues.
