[juraisi]

Hi guys ,
What's the max distance btween the BBU &RRU in huawei ?Is it free according to the optical specification,SFP ...,etc ?or it limited in other issues ?

Hi;

as I know it's dependent of SFP specification

Hi,
In our network RRU Supports 850nm Multimode Fiber only SFP Max of 2KM distance whereas a single mode fiber SFP in general can be used with max of 15 KM.

Hi,
The main limitation is not the SFP but the maximum delay that system supports between baseband and the remote radio. Every manufacturer should specify the maximum distance that they support. As techfolkcmr says, 15km is the common for 3G. In LTE is even longer. Then you should select the best SFP for every distance.
Kind regards.
