Bi-directional (BIDI) Fiber Optic Link Certification. Similar to PAIR mode, BIDI (bi-directional) mode allows users to quickly and conveniently certify a fiber pair in both directions at up to two wavelengths simultaneously, including length measurement with each test. Keep in mind that while bi-directional testing is not a requirement of cabling standards, it may still be required by the end user.

The Link Wizard in the Fiber OWL 7 uses attenuation parameters from popular cabling standards to certify fiber links, and shows complete PASS/FAIL test results for both fibers at both wavelengths, all on the same screen, right in the field.
