Definitions
- the invention is based on the genus as stated in independent claim 1. It is intended for use with frames in optical or electro-optical communications technology that are used to hold subracks with their assemblies.
- a device for kink-free deflection of optical waveguides which has two blocks, in each of which at least one groove-shaped guideway, which extends in an arc of approximately 90 °, is mounted for receiving the optical waveguides, the planes of the guideways of the two blocks being arranged at right angles to one another are (DE-Ul-94 12 895).
- the first block can have two guideways curved in the opposite direction.
- the present invention is concerned with the use of a universally usable device without kinks with a parallel offset in to continue in the same or in the opposite direction.
- optical fibers or cables coming from the outside into the interior of a frame without falling below the minimum bending radius of a conventional optical fiber (which could lead to losses due to attenuation or damage).
- the minimum bending radius of currently common optical fibers is 2 cm.
- the device according to the invention regardless of the frame shape (according to DIN 41494 or ETS standard); it can also perform its functions regardless of whether it is mounted on the left or right side of a frame. It can therefore be used universally.
- Figure 1 a part of a front view of a frame to which a device according to the invention is attached, whereby from this device the spouts above the drawing plane are omitted
- Figure 2 a partial view from the in Figure 1 with X marked direction, but with all four
- a device according to the invention is fastened to a frame spar 1, which carries a side wall 7, by means of a screw 2.
- This has a double angled holding plate 3, which carries four grommets a, b, c, d, the curved longitudinal directions of which lie in the common plane of the drawing in FIG. 2 and which lie opposite one another in pairs. All four spouts open into a common, central cavity 4. They are held together by two clamps 5 and 6, respectively, which are fastened to the holding plate 3.
- the grommets are arranged mirror-symmetrically to each other.
- the spouts a, b are arranged mirror-symmetrically to c, d, and the grommets a, c are mirror-symmetrical to b, d.
- each grommet runs in an arc of approximately 90 ° and has a radius of curvature R30 in the longitudinal direction which is greater than the minimum bending radius of optical fibers 8, 9, which are also shown in FIG. 2.
- the device can be mounted on the right side of the rack (as shown) or on the left side as required. This enables the mounting surface 3a of the holding plate 3, which is perpendicular to the direction in which the opposing pairs of grommets a-c and b-d open into one another.
- the optical fibers 8, 9 arriving on the frame front are first threaded through the grommets d, b and then through the other two grommets.
- the optical fiber 9 coming from direction B can be guided in direction C (as shown) or A within the cable space 10.
- An optical waveguide cable or optical waveguide 8 from direction D is guided in one of directions A or C accordingly.
- several optical fibers or cables can be led into the cable space 10 without kinks.
