Serial Cable Cisco CAB-ASYNC-8= Green 3 m

The Cisco CAB-ASYNC-8= Green 3 m is a 3-meter serial cable designed for stable asynchronous data transfer between networking devices. Manufactured to Cisco's compatibility standards, the cable uses durable connectors and a colour-coded green jacket for easy identification in rack and cabling environments. Its length and build make it suitable for console access, out-of-band management, and short-distance device interconnection within data centres and wiring closets.

Advantages

This serial cable provides reliable signal transmission through quality-moulded connectors and consistent impedance across the cable length. The 3 m length balances reach and manageability, reducing excess slack while enabling comfortable connections between devices in neighbouring racks or cabinets. The green outer jacket aids quick visual identification among other cables, and the robust construction supports repeated plugging cycles and routine maintenance tasks.

Suitable for

• Console access to routers, switches and network appliances
• Out-of-band management connections
• Short-distance serial links in wiring closets and data racks
• Lab, testing and configuration environments

Key specifications

• Cable length: 3 metres
• Colour: green outer jacket for visual identification
• Connector type: serial console-compatible moulded connectors
• Design: shielded construction for reduced interference
• Durability: reinforced strain relief for repeated use

How to use

Connect one end of the cable to the console or serial port of the Cisco device and the other end to the corresponding serial interface on the management station or terminal server. Ensure connectors are fully seated and secure to prevent intermittent connections. Configure the terminal application or management software with the appropriate serial settings (baud rate, parity, data bits and stop bits) required by the device. When disconnecting, grasp the moulded connector body rather than pulling the cable jacket to avoid damaging the strain relief.

Usage recommendations

Route the cable away from high-power electrical runs and strong RF sources to minimise potential interference. Use cable ties or Velcro straps to organise runs without over-tightening. For permanent or long-distance installations, evaluate alternative connection methods or longer cables to maintain signal integrity.
