This series includes DWDM tunable OTDR module to cover DWDM C-Band channels. This solution is available in the FTB-1V2, FTB-2 and FTB-4 platforms. The 740C xWDM OTDR series has been designed with EXFO’s renowned high-quality standards to stabilize central wavelength under test, preventing any drift/leakage into adjacent channels, which would otherwise affect other valuable customers. This OTDR is a scalable solution that can grow with your network by adding channels further down the road, hence allowing CAPEX reduction while covering your current and future needs. The OTDR’s user-friendly interface lets the technician define a list of favorite channels over the C-Band (DWDM) for quicker access and a more efficient test routine.
