AIRPORT TERMINAL
The airport terminal in this example has a main equipment room which houses the signal processing equipment,
along with four remote equipment rooms 250 feet apart along the length of the terminal. Each of the remote
rooms serves four gate areas, and each gate area is served by four audio channels—two in, and two out. There
are a total of 16 gates.
The analog solution
The analog system uses 1½-inch conduit in a direct run from each remote equipment room to the main equipment
room, for a total of 2,500 feet. From each remote equipment room to each of the four gate areas it serves is a
150-foot run of ¾-inch conduit, a total of 2,400 feet. Audio cabling throughout is 16,400 feet of four-pair shielded
copper wire.

Airport analog system
The RAVE solution
A single ¾-inch conduit runs the length of the terminal to accommodate the fiber optic cable connecting the main
equipment room with all of the remote equipment rooms. Three-quarter-inch conduit runs 150 feet long from
the remote equipment rooms to the gate areas carry 4-pair copper wire, the same as in the analog design.
The total amount of ¾-inch conduit used is 3,400 feet. Also used are 2,500 feet of 4-strand multimode fiber and
2,400 feet of 4-pair cable.
