Theory of Operation

This chapter describes the theory of operation for the node, including functional descriptions of each module
in the node.
The node is comprised of two parts, the lid and the base.
The lid houses an optical interface board (OIB), a Remote PHY device (optional), one or two power supplies,
and a fiber management tray/track.
The base houses the RF amplifier module, the high pass filter trim (HPFT) module and diplexer that plug
into it.
