When a single-mode fiber optic cable connects a BBU and an ODF, the optical fibers on the
BBU side and ODF side are 0.34 m (0.013 in.) and 0.8 m (0.031 in.) long, respectively.
When a single-mode fiber optic cable connects an ODF and an RRU, the optical fibers on the
RRU side and ODF side are 0.03 m (0.013 in.) and 0.8 m (0.031 in.) long, respectively.
Figure 3-7 shows the connections for a single-mode CPRI fiber optic cable between a BBU and
an ODF or between an ODF and an RRU.
