This is a 1-meter Type 2 stacking cable specifically designed for use with Cisco Catalyst switches, particularly the 3650 and 3850 series. While seemingly simple, this cable plays a crucial role in enterprise networking by enabling StackWise-160 technology — Cisco’s high-speed stacking protocol that allows multiple switches to operate as a single logical unit. By interconnecting switches using this stacking cable, network administrators can significantly improve both the scalability and resiliency of their switching infrastructure.
