The Huawei S1720 52GWR 4P E AC switch is a high performance, enterprise level network switch that offers a range of features and capabilities to support various network applications. Here's a breakdown of the key parameters mentioned in the product description:

1. 48 10/100/1000BASE T ports: This refers to the number of Ethernet ports on the switch that support three different speeds:

  10BASE T: Supports 10 Mbps Ethernet over twisted pair copper cables.

  100BASE T: Supports 100 Mbps Fast Ethernet over twisted pair copper cables.

  1000BASE T: Supports 1 Gbps Gigabit Ethernet over twisted pair copper cables.

These ports are versatile and can be used for connecting various types of devices, such as computers, servers, printers, and other network equipment.

2. 4 GE SFP ports: GE stands for Gigabit Ethernet, and SFP stands for Small Form factor Pluggable. These are high speed ports that use SFP (or SFP+) modules to connect with fiber optic cables for longer distance transmission or higher bandwidth requirements. Each of these ports can support data rates up to 1 Gbps.

3. Fixed AC power: This indicates that the switch is designed to be powered by an alternating current (AC) power source. The term "fixed" suggests that the power supply is an integral part of the switch and cannot be replaced with another type of power supply. AC power is common in most commercial and industrial environments.

4. E AC: This could be a model or series designation that Huawei uses for this particular switch. It might include additional features or specifications that are specific to this model.

The Huawei S1720 52GWR 4P E AC switch is designed for environments that require high speed data transfer and reliable network connectivity. Its mix of copper and fiber ports makes it suitable for a wide range of network configurations and applications.
