All-in-one Ethernet/optical FTB-700G Series and FTB-800 NetBlazer Series provide enhanced common public radio interface (CPRI) protocol testing solution. This feature helps field technicians to install and maintain fronthaul networks by testing connectivity and data integrity between remote radio head (RRH) and baseband unit (BBU) in fiber-fed cell towers. Also, CPRI functionality reduces unnecessary tower climbs. Both portable field testers also feature usability-optimized UIs.
