Optical Return Loss & Interferometry Testing

 Back Reflection Testing, Return Reflection and Return Loss are terms to describe the optical energy reflected back towards the source due to an air gap between two fibers. It is especially important in Singlemode systems to minimize return loss so that output power level of the source remains stable.

Global Fiber Optics Corp. can test your cable assemblies with an optical return loss meter to ensure you meet the specifications required by the end customer.

 Interferometry Testing is used in the fiber optic field to measure the three key physical endface parameters of a PC polished connector. These parameters include:

   Radius of Curvature

  Eccentricity of Polish (Apex Offset)

  Fiber Undercut or Protrusion (Fiber Height)

 Global Fiber Optics Corp. can provide hard copy Interferometry results.

 This test can also evaluate the radius of curvature and Apex offset of unterminated connectors and multiple fiber connectors. This process helps in the screening process to eliminate out of spec ferrules before connectorization.

 It is also useful in the measurement of protruded and recessed fibers especially in connector terminations where fibers should be protruded or recessed.

 The system provides information on fiber heights and curvature on sections of multi-fiber connectors.

 Adhesive reliability can be checked on fibers that have been pushed back due to temperature and pressure.
