Fiber Optic Distribution Networks
Fiber optic networks are setup identically to data networks by using either a star or daisy-chain
configuration. The two examples below illustrate part of a road covered by a BMU or RMU and
four FORs. Figure 1-15 illustrates a star configuration where a BMU is fed by a BTS via an RF
cable and four fiber optic ports that feed four FORs. The BMU has to be located very close to
the BTS.
Figure 1-15 Star Configuration Using One BMU and Four FORs
Figure 1-16 illustrates a daisy-chain configuration where a RMU with a donor antenna and one
fiber optic port feeds four FORs.
Figure 1-16 Daisy-chain Configuration Using One RMU and Four FORs
By using WDMs and OSPs in the FORs, the distribution net can be built up with a combination
of star and daisy-chain connections using double or single fiber.
