METHODS FOR PROCESSING FIBER OPTIC CABLES
The present disclosure relates generally to a method for processing an optical fiber. The coating is stripped from the cladding of the optical fiber using a stripping process. Direct heat is applied to the first side of the optical fiber and is not applied to the second side of the optical fiber. Then, the optical fiber is inserted into a fiber alignment structure with the second side of the optical fiber engaging a fiber alignment feature of the alignment structure. The first side of the optical fiber does not engage the fiber alignment feature.
1 . A method for processing an optical fiber having a coating surrounding a cladding and a core of the optical fiber, the optical fiber including a first side and an opposite second side, the method comprising:
stripping the coating from the cladding of the optical fiber using a stripping process in which direct heat is applied to the first side of the optical fiber and is not applied to the second side of the optical fiber;
inserting the optical fiber, after stripping, into a fiber alignment structure with the second side of the optical fiber engaging a fiber alignment feature of the alignment structure and the first side of the optical fiber not engaging the fiber alignment feature.
2 . The method of claim 1 , wherein the fiber alignment feature is a fiber alignment groove.
3 . The method of claim 2 , wherein the fiber alignment groove is a v-groove and the second side of the optical fiber faces toward the v-groove and engages groove-defining surfaces of the v-groove.
4 . The method of claim 2 or 3 , wherein the fiber alignment structure is used to mechanically align the optical fiber within a splice machine.
5 . The method of claim 1 , wherein the fiber alignment structure is a ferrule defining a fiber opening for receiving the optical fiber, wherein the fiber alignment feature is an internal surface of the ferrule which defines the fiber opening, and wherein the optical fiber is offset within the fiber opening to one side of the fiber opening such that the second side of the optical fiber engages the internal surface of the ferrule.
6 . The method of claim 4 , wherein the optical fiber is held by a clip during stripping and splicing, wherein the optical fiber projects outwardly from the clip, wherein the clip includes a first side that faces in the same direction as the first side of the optical fiber and a second side that faces in the same direction as the second side of the optical fiber, wherein optical fiber is stripped at a stripping device and is spliced to another optical fiber at the splice machine, wherein the stripping device includes a first receptacle for receiving the clip during stripping and the splicing device includes a second receptacle for receiving the clip during splicing, wherein the clip is mounted in the first receptacle during stripping of the optical fiber with the first side of the clip facing the first receptacle and the second side of the clip facing a cover for securing the clip in the first receptacle, and wherein the clip is mounted in the second receptacle during splicing with the second side of the clip facing the second receptacle and the first side of the clip facing a cover for securing the clip in the second receptacle.
7 . The method of claim 6 , wherein the stripping device includes a heated surface and a non-heated surface, and wherein during the stripping process the optical fiber is pressed between the heated surface and the non-heated surface with the first side of the optical fiber contacting the heated surface and the second side of the optical fiber contacting the non-heated surface.
