Outdoor Electronic Equipment
Lian-Tuu Yeh, Richard C. Chu · ASME Press eBooks · 2013
The outdoor electronic equipment includes a large variety of various types of systems. Among them are the outside plant (OSP) and the remote radio head (RRH) for telecommunication applications. The OSP refers to all of the physical cabling and supporting infrastructure such as conduit, cabinets, towers or poles, and any associated hardware located between a demarcation point in a switching facility and a demarcation point in another switching center or customer premises. On the other hand, the RRH describes an operator radio control panel that connects to a remote radio transceiver via electrical or wireless interface. From the methods of equipment mounting, the outdoor system can generally be classified into two groups. One is the ground or vehicle mounted equipment and another is the tower or pole mounted systems.
