产品描述：
The E6007A Visual Fault Finder Sub-Module is a visible light source that helps you to identify bends, breaks and stress points along individual fibers at the patch panel. The bright red light allows you to locate these faults within the deadzone of an OTDR, and at distances of up to 5 km. The unit can be used to identify fibers within a cable and also to check the quality of your patchcords and connections. The 1Hz modulation causes the light to flash, making it easier to identify fibers and locate faults.
The E6007A Visual Fault Finder Sub-Module is a plug-in module for the E6000B Mini-OTDR Mainframe.
