Your example is from the source '1' side (RDF-1). Therefore the active cycle is capturing host writes into cache. The inactive cycle refers to the period of transmitting across the link.
If you were doing symstat against the Target Array (RDF-2), 'Active' would refer to writing data to the R2 device , and 'Inactive' would be receiving data from the link.
Thanks Paul, the guide was helpful, But what i really want to understand is ,
When the R1 symm is capturing data for say 15 sec cycle time, Is the transmit happening at the same time for previous capture cycle, or does it happen once Capture is complete.

Scott is correct here. And for further information the statistics from symstat are also discussed in the array management cli guide https://support.emc.com/docu46983_Solutions_Enabler_Symmetrix_Array_Management_CLI__7.6_Product_Guide.pdf?language=en_US
You have a full explanation on Page 266 on this particular output
