1 Introducing the FTB-700 OTDR
The FTB-700 OTDR allows you to characterize a fiber-optic span, usually
optical fiber sections joined by splices and connectors. The optical time
domain reflectometer (OTDR) provides an inside view of the fiber, and can
calculate fiber length, attenuation, breaks, total return loss, and splice,
connector and total losses.
