Node Optical Test Access Unit

Large, Dense 1xN Optical Test Access Unit

Optical test access units (OTAUs) are used to programmatically connect a fiber under test to test equipment through an optical switching subsystem.

This product can create a temporary and low-insertion loss optical path between the test equipment and the fiber when characterizing, troubleshooting or testing any degradation (monitored).

OTAUs are designed to be connected to an OTDR, specifically EXFO’s Fiber Guardian, thus allowing a single instrument to test up to 720 fibers in a very dense capacity.
