2 EQUIPMENT DESCRIPTION
2.1 SYSTEM DIAGRAM
Figure 3: System Diagram
On the DL, signals from the BTSs or BDA are converted into optical signals after amplification in the
MU.Then the optical signals are transmitted to the RU via optical fiber. The Optical TX/RX Module of RU
converts the DL optical signals into RF signals. After amplification, the signals are transmitted at the MT
port to the service antenna.
On the UL, the signals transmitted by the mobile are converted into optical signals, and then via the UL
optical fiber, the signals are transmitted to MU, which then converts the optical signals back to RF signals.
2.2 TYPICAL APPLICATION
Shown below are the typical SISO applications of MU and RUs.
