3.2.2 Base Units
Depending on the Base Unit model, each Base Unit drives up to four or eight
remotes via duplex F/O connection, where each remote can be as far as 2
kilometers (1¼ miles) from the BU. Eight port BU consist of two four port BU that
are integrated.
During power-up, the Base Unit identifies the active connected RHUs that are
connected to that Base Unit and each of the corresponding link LEDs is lit according.
