  • Equipment 10 is just one example of equipment usable with a cable fixation device 14 on each end 20, 22, as will be described below.
  • Equipment 10 can include other functions, such as splitting, multiplexing, terminations, or storage. Further, cable pathways 24, 26, 28, 30 can be located as desired in equipment 10.
  • Equipment 10 can include more or less cable fixation devices 14.
  • Fixation devices 14 in the illustrated embodiment allow for fixation of one or more cables at each end of equipment 10.
  • two fixation devices 14 are provided, one on each end 20, 22.
  • Fixation device 14 allows for two cables to enter, one in each adjacent cable pathway 24, 26 or cable pathway 28, 30 for clamping. More cables of the same kind can enter each cable pathway 24, 26, 28, 30 and can be clamped by the fixation device 14.
  • each cable fixation device 14 includes an inner pathway 40 positioned between cable pathways 24, 26.
  • Each fixation device 14 defines a longitudinal axis 34. As shown, cable pathways 24, 26 are generally parallel to the longitudinal axis 34.
  • Two clamping fingers 42, 44 allow for a portion of the cable to be wrapped around and clamped by a clamp 46.
  • Clamp 46 includes a wedge 48 with outside surfaces 50, 52. Outside surfaces 50, 52 of wedge 48 face inside surfaces 60, 62 of inner pathway 40 defined by surfaces on clamping fingers 42, 44.
  • Wedge 48 is attached to base 16 with a fastener 70.
  • Wedge 48 includes a slot 72 which is sized so as to allow movement of wedge 48 in two directions, an X direction 74 which is parallel to inner pathway 40, and a Y direction 76 which is transverse to inner pathway 40.
  • Wedge 48 is movable in two directions to accommodate different thicknesses of the elements to be clamped.
  • Fastener 70 fastens to base 16 and is loosened to allow movement of wedge 48 during set up, installation of additional cables, or adjustment.
  • a cable in first cable pathway 24 can be spliced to a cable in third cable pathway 28. Further a cable in second cable pathway 26 can be spliced to a cable in fourth cable pathway 30. Other variations of cabling are possible.
  • Wedge 48 of the fixation device 14 at each end 20, 22 can clamp to two cables at the same time.
  • a first cable 100 is shown held by the cable fixation device 14.
  • First cable 100 is in first cable pathway 24, a first outer jacket 102 is held by a foam wrap 80 and a tie 82 which is received in tab 84 to mount first cable 100 to base 16. Tie 82 is received tab 84 including two holes.
  • An inner jacket 104 continues into equipment 10.
  • One or more fibers 106 extend from inner jacket 104, such as for splicing.
  • a strength member 108 in the form of aramid yarn is wrapped around clamping finger 42 and clamped by wedge 48 and first clamping finger 42.
  • a second cable 110 is positioned in second cable pathway 26.
  • Second cable 110 is held by a foam wrap 80 and a tie 82 affixed to tab 84.

  • the middle of the cable has a thinner dimension than the two outer portions containing the strength members.
  • Other cables besides the example cables 100, 110 can be held by fixation device 14.
  • FIG. 11 shows cable fixation device 14 clamping one first cable 100 and four second cables 110. Space savings is realized by having one device clamp more than one cable.
  • FIG. 12 shows an alternative embodiment for cable fixation device 14'.
  • Alternative first clamping finger 142 and alternative second clamping finger 144 have inclined surfaces 160, 162 in an opposite direction to the inclined surfaces 50, 52 of first and second clamping fingers 42, 44.
  • Wedge 148 may act to further tighten against the cable strength members and/or jackets in the event of a pull force being exerted on the cable or cables.
  • two different kinds of cables can be fixed, such as feeder cables 100 and drop cables 110.
  • the moveable wedge 48 can clamp to both cables in the cable fixation device 14. The portions of the cables being clamped have different dimensions.
