Description

BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWINGS

[0011] The herein described disclosure will be more fully understood from the detailed description given herein below and the accompanying drawings which should not be considered limiting to the disclosure described in the appended claims. The drawings are showing:

[0012] FIG. 1 shows a stack of SFO-boxes in a perspective view from above and the front;

[0013] FIG. 2 shows an SFO-box in a disassembled view and a base plate;

[0014] FIG. 3 shows an SFO box in an open position with several optical fan out modules; and

[0015] FIG. 4 shows the stack according to FIG. 1 in a perspective view from below and the rear.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0016] Reference will now be made in detail to certain embodiments, examples of which are illustrated in the accompanying drawings, in which some, but not all features are shown. Indeed, embodiments disclosed herein may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Whenever possible, like reference numbers will be used to refer to like components or parts.

[0017] FIG. 1 shows a stack of SFO-boxes 1 in a perspective view from the front and above. FIG. 2 shows an SFO-box 1 according to FIG. 1 in an exploded view along with a base plate 11. FIG. 3 is showing the inside of an SFO-box. FIG. 4 is showing the stack of SFO-boxes 1 in a perspective view from the back and below.

[0018] In the shown variation, the in a first direction (z-direction) stackable SFO-box 1 comprises a housing 2 with a base 3 and a top 4 which in an assembled position, as e.g., shown in FIG. 1 and FIG. 4, encompass a mounting space 5 suitable to receive at least one optical fan out module 6 (see FIG. 3) therein. The top 4 comprises first fastening means 7 and the base 3 comprises second fastening means 8 which are with respect to their layout compatible to each other such that two assembled housings 2 can be attached to each other in a stackable manner by interconnecting the first fastening means 7 of the top 4 and the second fastening means 8 of the base 3 by first screws 12 as e.g., shown in FIG. 1 and FIG. 4. In the shown variation the screws are arranged in the first direction (z-direction). At least one of the fastening means 7, 8 can be equipped with a thread.

[0019] As shown, the base 3 and the top 4 can have an essentially L-shaped cross-section interconnectable to each other to form the housing 2 which in the assembled position is having an essentially rectangular cross-section. In the shown variation, the base 3 and the top 4 are interconnected to each other by second screws 19 which are arranged in a second direction (x-direction) perpendicular to the first direction (z-direction). Thereby the housing 2 can be opened via the second screws even though the stack is not disassembled. The base 3 and/or the top 4 may comprise at least one mounting means 9 suitable to receive at least one optical fan out module 6. As visible in FIG. 2, the mounting means 9 can be in the form of a retaining mandrel 9 onto which the at least one optical fan out module 6 can be pushed onto as schematically indicated in FIG. 3. The base 3 and the top 4 of two adjacent housings 2 are in a stacked position interconnected to each other by first screws 12. The base 3 and the top 4 of one housing 2 are interconnected to each other by second screws 19. Alternatively, or in addition, the base 3 and the top 4 can in a mounted position be interconnected to each other by at least one hinge (not shown in detail). Good results can be achieved when the base 3 and the top 4 are made from bend sheet metal and/or injection molded plastic material. If made from sheet metal or injection molded plastic material, the hinge can be integrated into the material. The housing 2 preferably comprises in a mounted position an opening 14 for routing of optical cables 15 coming from and going to the at least one optical fan out module 6 arranged inside the housing 2 wherein the opening 14 is in particular arranged at the lower end of the housing 2. As e.g., visible in FIG. 4, the opening 14 is formed by the base 3 and the top 4 of the housing 2. This offers the advantage that the inside becomes fully accessible and thereby the routing of the optical cable 15 very easy, when the top 4 is separated from the bottom 3 of one housing. The base 3 and/or the top 4 of the housing 2 may comprise a deflector 16 for deflecting of the at least one optical cable 15, wherein in a mounted position of the housing 2 the deflector 16 is in particular arranged in the area of the upper end of the housing 2. The base 3 and/or the top 4 of the housing 2 may comprise at least one adapter 17 to interconnect two optical connectors 18 to each other. The adapter 17 is preferably arranged in the area of the opening 14. If appropriate a fixture 20 can be foreseen as e.g., visible in FIG. 3 and FIG. 4 to mount the adapter 17 in the housing 2. Usually SFO-box system 10 comprises at least one splitter SFO-box 1 as described above and a base plate 11. The base plate 11 usually comprises third fastening means 13 suitable to connect to the second fastening means 8 of the base 3 of the housing 2.

[0020] Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the Spirit and scope of the disclosure.
