Cold aisle heat dissipation cabinet
Cold Aisle Containment or CAC is a proven, relatively easy to deploy solution for effectively managing airflow within a data centre. A CAC system surrounds the cold aisle and it keeps cold supply air separate from hot server exhaust air. Essentially creating a room within the aisle, the system helps keep hot and cold air separated to make existing air conditioning systems in data center and edge-of-network. The aisle containment system is a modular rowbased thermal containment solution, which separates cold and hot data center air streams to and from equipment. This method raises the temperature of the air returning to a Computer Room Air Con itioner (CRAC) unit, which allows the unit to operate more eficiently.

Which device in a passive optical network PON doesn t require electricity
Since the optical splitters require no external power, there is no need for active electronics or cooling systems between the central office and the customer. This lack of powered equipment drastically reduces ongoing operational expenses related to electricity consumption and site. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment.
