Hi,  

Who knows RRU Label Descrition?  For Example RRU.B03-1800.K.120 and RRU.B03-1800.Z.120.    
In here, what does K.120 and Z.120 mean?  What is their difference?

Hello, zarcan.
Very clear picture. The information on the configuration label includes:
Module name, frequency band, sub-band, maximum output power, number of transceiver channels, number of carriers, CPRI interface type (optical port is SFP), interface rate, AC, or DC power supply.
K and Z represent sub-frequency.
Thanks!

What does this sub-band means ? Can you more clearly explain K and Z difference.

Simply put, it divides the uplink and downlink. K means UL: 1730-1780 DL: 1825-1875. Z means UL: 1710-1785 DL: 1805-1880.

Maybe you are viewing Z's information or the label is wrong. Mark Z as K.

RRU may have the wrong label attached.

Hello, zarcan.
Are you using Huawei products? Huawei does not seem to have such an RRU model. Where is your label? Can you provide some pictures? According to experience, A-Z should indicate the production time.
Thanks!
