Questions & Answers

What types of cables and adapters does Cisco offer?

Cisco offers a full range of copper and fiber optic solutions, including Cat5e/Cat6/Cat6A RJ45 cables, LC/SC/ST fiber cables, Direct Attach Copper (DAC), Active Optical Cables (AOC), and compatible SFP, SFP+, QSFP+ and QSFP28 transceiver modules.

How do I choose the right Cisco cable for my network?

Select cables based on required bandwidth, distance and infrastructure. Use DAC for short 10m connections, Cat6A for up to 10G over 100m, AOC for 40–100G beyond 7m, and fiber cables (LC/SC) per transceiver specifications.

What is a Cisco Direct Attach Cable (DAC)?

A Cisco Direct Attach Cable (DAC) is a passive twinax copper assembly for short-reach links up to 7m. It delivers low latency and power consumption, making it ideal for data center top-of-rack switch-to-server connections.

What is an Active Optical Cable (AOC) and when should I use it?

An Active Optical Cable (AOC) integrates optical transceivers with fiber to support high-speed links (10G–100G) over distances from 10m to 100m. It’s lightweight, EMI-resistant, and ideal for data center and telecom deployments.
