A standard connector used for Ethernet networking that connects cables to network devices.

Patch Panel

A panel where network cables are terminated, allowing quick connection and management of network circuits.

Fiber Optic Distribution Panel

A panel that manages fiber optic connections, ensuring proper handling such as maintaining bend radius.

Service Loop

19-inch Rack

A standardized rack size that measures 19 inches across, commonly used for mounting networking equipment.

MDF Facility
