Abstract
A fiber optic test device is provided that includes a light source pigtailed with a first end of a non-bend insensitive multimode fiber (non-BIMMF). A second end of the non-BIMMF is fusion spliced to a first end of a reference grade bend insensitive multimode fiber (BIMMF). A reference grade optical fiber connector is attached to a second end of the BIMMF, which is coupled to a first end of a reference grade bulkhead adapter. The non-BIMMF is deformed so that a specific launch condition, such as encircled flux, is achieved at the first end of the BIMMF. A test reference cord, which contains a reference grade BIMMF having similar geometric properties as the BIMMF that is fusion spliced to the non-BIMMF, is attached to a second end of the bulkhead adapter. Modal transparency is achieved and the launch condition is maintained at the output of the test reference cord.
