In short, the OTDR Launch Box, is actually a long spool of dummy optical fiber inserted between the fiber under test and OTDR, and can ensure that the OTDR dead zone happens in the OTDR launch box. In this way, the fiber optic link under test won’t be largely affected by the OTDR dead zone.
Did you know that Multicom’s MUL-OTDR-1100 is the highest quality and best priced OTDRs on the market?
