ABSTRACT:
A gain equalizing device capable of realizing optimum gain equalization according to the amplification characteristic of a repeater and the transmission characteristic of a cable. The gain equalizing device includes a pressure-resistant housing consisting of a cylinder and first and second covers welded to the opposite ends of the cylinder. A plurality of optical fibers of a first tail cable are introduced into the pressure-resistant housing through a first feed through mounted to the first cover, and a plurality of optical fibers of a second tail cable are introduced into the pressure-resistant housing through a second feed through mounted to the second cover. A mounting plate is mounted on the first cover, and a plurality of optical equalizing modules are mounted on the mounting plate. A fiber accommodating structure accommodating a plurality of splice portions for respectively splicing the optical fibers of the first tail cable to the optical fibers of the second tail cable is mounted on the second cover.
