Dell DELL-WD25TB4 Performance Thunderbolt 4 Docking Station
Overview
The Dell WD25TB4 is a next-generation Thunderbolt 4 enterprise docking station designed for high-performance laptops, mobile workstations, and IT-managed fleets. It consolidates display output, high-speed data, network connectivity, and power delivery into a single USB-C/Thunderbolt cable for workstation-class deployments.
It is built on a Thunderbolt 4 (USB-C) interface with 40 Gb/s bandwidth, enabling support for complex multi-display and peripheral-heavy setups. The dock supports up to 4 external displays, including configurations such as dual 6K or quad 4K depending on host system capability.
Video output options include DisplayPort 1.4, HDMI 2.1, and USB-C Alt Mode, along with dual Thunderbolt downstream ports for chaining additional devices.
Power delivery is handled via a 180W external adapter, supplying up to 130W to Dell laptops and reduced wattage profiles for non-Dell systems.
Enterprise integration features include PXE boot, MAC address pass-through, and Intel vPro/AMT support (on compatible systems), making it suitable for managed corporate deployments where remote provisioning and security controls are required.
Deployment use cases include engineering workstations, financial trading desks, and hybrid office setups requiring high-bandwidth docking with multiple displays and wired networking. It is not intended for consumer casual docking or low-cost plug-and-play setups due to its firmware dependency and enterprise configuration model.
