The BTS-DAS Fiber Transport Link by Optical Zonu pro-vides a simple, cost-effective and reliable RF connec-tion between the base station location and the DAS headend. Each link supports multiple carriers and mul-tiple bands from 100 – 2700 MHz independent of modulation technology. A high dynamic range ensures a transparent pass through with no distortion or mix-ing. Utilizing CWDM, The BTS-DAS FTL combines multi-ple wireless bands and services on a single fiber. The units come in a 1U high rack mount chassis with 1, 2, 3, or 4 channels and these units can be stacked as needed. A link with a single 1U high rack mount chas-sis at each end provides a simple and robust connec-tion for two MIMO or four SISO sectors. Six channels can be supported by adding the 2 channel Expansion Unit to the 4 channel unit with the Express Port. This configuration supports three MIMO or six SISO sectors.

The Master Base/DAS Unit pair includes 1 GbE data link over the same fiber. This link uses Optical Zonu’s SFP with built-in OTDR, so the occurrence and loca-tion of any fiber break is reported automatically.
