QSFP-100G-AOC30M Cisco 30m Active Optical Cable – 100GBase

CAB-STK-E-3M Overview

The Cisco CAB‑STK‑E‑3M StackWise Plus Stacking Cable (10 ft / ~3 m) is a specialized high‑speed interconnect cable used to stack compatible Cisco Catalyst switches—especially models that support Cisco StackWise Plus technology—so that multiple physical switches operate together as a single logical unit. By linking the stack ports on each switch with this robust cable, you enable shared management, synchronized configuration, increased redundancy, and higher aggregate throughput across the entire stack. At approximately 10 feet long, this cable is ideal for rack installations where switch stack members are spaced farther apart, offering flexibility in physical placement while maintaining reliable, low‑latency communication between devices.
