摘要： An optical fiber has at least one optical sensor with at least two interconnects with associated insertion losses. A first optical sensing interrogator is coupled through an interconnect to one end of the optical fiber with the sensors, and a second optical sensing interrogator is coupled through an interconnect to an opposite end of the optical fiber on an opposite side of the sensors. The first optical sensing interrogator and the second optical sensing interrogator determine one or more fiber insertion losses associated with the optical path in between the sensors and the interrogators, and between sensors if there are two or more sensors, without foreknowledge of the sensor reflectivity.

摘要： A catheter system (100) for treating a treatment site (106) within or adjacent to a vessel wall (108A) or a heart valve includes a light source (124), a first light guide (122A), a second light guide (122A), and a guide bundle (152). The light source (124) generates light energy. The first light guide (122A) receives the light energy from the light source (124) and has a guide proximal end (122P). The second light guide (122A) receives the light energy from the light source (124) and has a guide proximal end (122P). A guide bundle (152) is in optical communication with the light source (124). The guide bundle (152) bundles the first light guide (122A) and the second light guide (122A). The guide bundle (152) includes a first ferrule (778) that engages the guide proximal end (122P) of the first light guide (122A) and a second ferrule (778) that engages the guide proximal end (122P) of the second light guide (122A). At least one of the ferrules (778) can be formed at least partially from a ceramic material or a metallic material.

摘要： 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.
