What type of switch is used in the access layer
The access layer consists of layer 3 switches, which take routed and switched data packets from the distribution switches and then route them to the access devices in subnets. The access devices in subnets can be modems, video display units, receiver audio phones, IP-based. The layer 2 switches collect the data from core switches, identify the type of data packet and the address of the access device. Therefore, this. An access switch is a network edge device that directly connects end-user hardware such as computers, IP phones, wireless access points, cameras, and IoT devices to the broader network. In a typical enterprise network architecture, the access layer serves as the entry point for end. Because the access layer's primary function is to allow end users to connect to the network, access layer switches are frequently low cost and have high port density. It is generally advised to use low-cost equipment.

What type of cable is used in outdoor cable trays
TC (tray cable, per NEC Article 336, UL 1277) is a versatile cable suitable for use in cable trays, raceways and even direct burial (if specifically rated). Many cable tray rated cables include a crush and impact test as part of the listing and are rated as exposure rated (ER). Unlike standard electrical cables, tray cables feature enhanced insulation and jacketing to withstand mechanical stress and exposure to oil, sunlight. Cable trays are used in a variety of electrical systems, where cable trays have their importance. Tray resistant establishments support commercial induses. While automotive, wind energy, and petrochemical industries benefit from using tray cables.
