When to use an OTDR vs light source power meters

The ongoing data center and enterprise network challenge to rapidly migrate to 40 and 100G transmission speeds (with 200 and 400G on the horizon) coupled with ongoing changes in connectivity—such as parallel optics, PAM4, and OM5 wide band multimode fiber with short wavelength division multiplexing (SWDM)— requires less tolerance for errors and much tighter loss budgets. These ever-increasing transmission speeds in conjunction with more complex connectivity heighten the probability that connection reflectance could lead to network failure. Consequently, accurate and comprehensive testing and measurement is more crucial today than ever before.
