This amplifier was designed as a bridging amplifier between models SSPA0.8-4.5-5 and SSPAO,6-2.0-20.
The first feder amplifier is actually located within the trunk amplifier station housing and is called a bridging amplifier. The bridging amplifier receives signal from the trunk, raises the level and provides the source signal for up to four individual trunk station feeder cables.
In fact, in many cases, the institutional feeder system simply consists of the bridging amplifier and direct cable connection to the user.
