In order to prevent signal line crossing and facilitate maintenance of functional areas, the best arrangement order from bottom to top is optical transceivers ->bridges ->routers ->switches. Large equipment is installed at the bottom of the cabinet and supported by cabinet trays. Due to their small size and large quantity, fiber optic transceivers cannot be fixedly installed in cabinets and are also installed on trays. 5.
