When dual fiber is measured, arrows at the top of the screen point out the direction of the light. The arrows also indicate the fiber that the (PASS) or (FAIL) result is for.

  • Page 95: Chapter 8 - Fiber Optic Reference Methods

    OMNIScanner User Guide Chapter 8 – Fiber Optic Reference Methods Establishing the Reference Different methods can be used when making a reference measurement with OMNI Fiber. The reference measurement to use depends on how the standard defines the link, and how the network is interconnected. There are three basic link definitions and three corresponding reference methods.

    The Reference Methods For testing of networks with different connector styles, please consult the Microtest web site (http://www.microtest.com/support/techbulletins/). It is very important that the transmitter (TX port) connections are not dis- turbed after the reference value is established. Note: When a connector is removed and then reattached, it is unlikely to go back into the exact same position.
