settings for the RU.

OP Info

The OP Info section displays the current optical port connection
status and information reading volume of the device.

Downlink/Uplink Config

The Downlink/Uplink Config section allows you to configure
settings related to downlink and uplink power.

Downlink Output Power Config (Power Sharing Process)

This step-by-step process guides you on how to configure the
downlink output power for power sharing. It involves setting the
Carrier Info and RIU ATT parameters to meet the DCU input power
range.

Uplink Gain Config

The Uplink Gain Config section provides instructions on how to
configure the uplink gain. It involves setting the RIU UL ATT, DCU
UL ATT, and RU UL ATT parameters.

5.6 Downlink/Uplink Config
5.6.1 Downlink Output Power Config (Power Sharing Process)
Step 1. Set Carrier Info in Chapter 5.3.1.3, including the operator info, carrier info. The DL ATT can be set to default value in power sharing config.

Figure 154. Power sharing
Step 2. Set the power sharing parameters in chapter 5.3.1.4 – Assign each operator’s power share (percentage). – Select the carrier’s power assignment mode for each operator (Density /Even). Density mode: power assignment based on carrier bandwidth. Even mode: power assignment based on the carrier number. – Config MIMO 1 and MIMO 2 channel. – Select the calculate button to active the value, then the DL ATT value in Step 1 will be automatically calculated. – Select the `Power Share Lock’ button to lock the ATT config. – The system will automatically emit the output target power based on power sharing configuration if the DCU input power is within the operation range.

OFF (Gain = -30dB)

0~25

In this case, please config the DCU to the following config. The detailed config is listed in chapter 5.2.2 High Gain mode = OFF DCU DL ATT changes from 20dB to 0dB after antenna connection.

5.6.2 Uplink Gain Config

The Total Uplink Gain = -2dB – RIU UL ATT – DCU UL ATT – RU UL ATT Step 1. Config the RIU UL ATT according to chapter 5.1.2 Step 2. Config the DCU UL ATT according to chapter 5.2.2.2 Step 3. Config the RU UL ATT according to chapter 5.4.2.2 The range of each ATT is listed as below.
