OFI-20A can detect optical signal presence, type and direction anywhere on fibers during a optical network deployment, maintenance or troubleshooting. With non-destructive macro-bend detection technology, it introduces no damage to tested fiber or interference to the service on fiber. OFI-20A is capable of identifying wide-spectrum signals (such as signals in CATV system) and can be used in SONET/SDH & DWDM systems tests.
