  • FIG. 1 shows a first optical cable 100 including at least one optical fiber, electrical conductor, or other transmission media 102 disposed within a cable jacket 104.
  • the jacket 104 surrounds multiple buffered optical fibers 102 (i.e., optical fibers disposed within buffer tubes).
  • the optical fibers 102 may be bare optical fibers.
  • the buffered optical fibers 102 are wrapped around a central longitudinal axis of the cable 100.
  • the buffered optical fibers 102 may be wrapped around a strength member 109 (FIG. 4) extending along a longitudinal axis of the cable 100.
  • the optical fibers 102 may be ribbonized.
  • one or more electrical conductors may be helically wound, twisted, braided, or otherwise arranged within the jacket 104.
  • a section 106 of the jacket 104 has been separated from the rest of the jacket 104 and peeled away from the optical fibers, electrical conductors, or other transmission media 102.
  • the jacket section 106 may be separated from the rest of the jacket 104 by cutting the jacket 104 along a length of the jacket 104 at a first circumferential position and cutting the jacket 104 again along the length at a second circumferential position that is circumferentially spaced from the first position.
  • the jacket 104 is cut at two circumferential positions, thereby splitting the jacket 1104 into two sections 106.
  • the jacket sections 106 are at least approximately the same size.
  • the jacket sections 106 may be different sizes.
  • the jacket 104 may be cut at additional circumferential positions to form three or more strips 106.

  • a fixation device 110 is shown
  • the fixation device 110 includes a first part 111 having a first surface 112 and a second part 113 having a second surface 114 that faces the first surface 112. The first and second surfaces 112, 114 are separated by a gap 115.

  • the strip 106 is laid or wrapped over a curved surface 112a or corner when inserted into the gap 115. The curved surface 112a provides resistance (e.g., friction) to aid in retaining the jacket strip 106 within the gap 115.
  • the jacket strips 106 are flexed, bent, or folded away from the optical fibers, conductors, or other transmission media 102 and routed into the gaps 115.

In some implementations, the first part 111 moves and the second part 113 remains stationary. In other implementations, the second part 113 moves and the first part 111 remains stationary. In other implementations, both parts 111, 113 move towards each other to compress the j acket strip 106. In still other implementations, both surfaces 112, 114 remain stationary and an actuator member pushes the cable strip 106 against one of the surfaces 112, 114 as will be described in more detail herein (see FIGS. 6 and 8)

  • Clamp device includes first and second clamp bars 502, 504 which are held in place under loop 506 on one end, and a fastener 510 on an opposite end. Positioned between each of the clamp bars 502, 504 is a portion of jacket strip 106 bent backwards 180°.
  • halves 290 are not identical. One difference is in the location of the clamp device 500 so that the clamp device 500 of each half 290 is not directly opposed to one another, allowing a more compact design.
  • First half 292, once fixed to its cable is inserted into body 221.
  • Second half 294, once mounted to its cable, is then inserted into body 221, resulting in the staggered locations of clamp devices 500 (see FIG. 19).
  • the aramide yarn of the cable may be present.
  • the aramide yarn and the jacket strip 106 can be held by the clamp device. In this case, the jacket forms a semi-soft material to hold the aramide yarn in place.
  • Fixation device 200 including clamp bars 502, 504 can be made from metal.
  • Seal blocks 620 can be used to seal cables at ports 609 of enclosure 600, shown for example in FIGS. 22 and 23.
  • Enclosure 600 includes a base 604, a cover 606 and latches 608.
  • Seal block 620 includes one or more of the cable fixation devices noted above.

Abstract

Selon l'invention, un câble (100) peut être fixé à un objet, tel qu'un orifice de câble d'une enceinte, à l'aide d'une ou plusieurs bandes (106) du revêtement (104) du câble (100). Les bandes (106) peuvent être fixées à un dispositif de fixation (110, 120, 130, 140, 150, 160, 170, 180, 190, 200) qui est fixé à l'objet. Certains types de dispositifs de fixation (110, 120, 130, 140, 150, 160, 170, 180, 200) sont configurés pour appliquer une pression de serrage à la partie d'extrémité à bande du revêtement de câble lorsque la partie d'extrémité à bande est positionnée entre des première et seconde surfaces du dispositif de fixation. Certains types de dispositifs de fixation (190) sont configurés pour avoir les régions à bande (106) filetées à travers les dispositifs de fixation (190) et enroulées autour de ceux-ci pour attacher le câble (100).
