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 from RU ANT port to the service antenna using 50Ohm coaxial cable.
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 and send to BTS or BDA via 50Ohm coaxial cable.

The site consideration for RU is listed below: The distance between the service antenna of RU and coverage area should satisfy line of sight
requirements for maximum coverage area.
The maximum fiber length is 8 miles, with a maximum path loss of 6.5dBo.  The system delay of the optical system must be taken into consideration when there are neighboring
BTS sites overlapping in coverage.
Installation Location
Mounting surface shall be capable of supporting the weight of the equipment. In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize
interference from electromagnetic sources such as large electrical equipment.
Environmental
Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the equipment in locations having stable temperature and unrestricted air-flow.
The installation location for the system should be well ventilated. The equipment has been designed to operate at the temperature range and humidity level as stated in the product specifications.
Powering
The power supply unit (PSU) provides power to all modules within the equipment. Depending on the product variant, it is recommended that the PSU operates on a dedicated AC circuit breaker or fused circuit.
Grounding Requirement
Verify that the equipment has been well grounded. This includes antennas and all cables connected to the system. Ensure lightning protection for the antennas is properly grounded.

Step 8: Click to enter to [Finish] page after finishing RU setup. Note:
As the system calibration process is calibrated for single channel, so if there is more than one same band input, because of the power superposition, the band total output power will higer than target DL output power after the calibration is complete.
The calibration work is mainly to set device to reach it’s theoretical gain, so when there are two or more
same bands access into and they have the same input power level, each channel will reach it’s rated
power, so the total output power will be (input A+gain) + (inputB+gain)+…+(inputN+gain). For example, if
there are two 1900MHz bands acess to MU, each has 10dBm input power, the total output power of RU 1900MHz will be 30dBm+30dBm=33dBm.
Refer to the method below for the gain adjustment: Suppose a band with N independent inputs, each input signal power are all X dBm. Apparently, there exists the following relationship between input and output after finished auto communication on WEB GUI: X dBm + Gain = 30dBm, then the total output power for N channels access is X dBm + Gain + 10*Log(N) = 30 + 10*Log(N), so Users need to set 10*Log(N) RFU ATT on WEB GUI for each channel.
