Abstract

The present invention relates to an attachment (optical fiber sidecar) to the outer casing of a component of an RF distribution system, which provides a sealed enclosure in which one or more individual optical fibers may be separated from a main optical fiber transmission medium, and a conduit through which the individual fibers may be passed for connection to components housed in the RF casing.

Claims

1. An optical fiber sidecar comprising:

an enclosure having an entrance opening and an exit opening through which a fiber cable containing at least one continuous optical fiber is passed;

said enclosure including means for positioning one or more optical fibers within said enclosure such that the minimum bend radius of each optical fiber is not exceeded;

said enclosure including a conduit separate from said entrance and exit openings, said conduit having conduit means for passing one or more optical fibers from within said enclosure; and

wherein said enclosure and said conduit means are water-tight and pressure-tight.

2. An optical fiber sidecar comprising:

an enclosure having an entrance opening and an exit opening through which a fiber cable containing at least one continuous optical fiber is passed;

said enclosure including means for positioning one or more optical fibers within said enclosure such that the minimum bend radius of each optical fiber is not exceeded;

said enclosure including a conduit separate from said entrance and exit openings, said conduit having conduit means for passing one or more optical fibers from within said enclosure; and

wherein said enclosure and said conduit means are shielded against electromagnetic interference leakage.

3. An optical fiber sidecar comprising:

an enclosure having an entrance opening and an exit opening through which a fiber cable containing at least one continuous optical fiber is passed;

said enclosure including means for positioning one or more optical fibers within said enclosure such that the minimum bend radius of each optical fiber is not exceeded;

said enclosure including a conduit separate from said entrance and exit openings, said conduit having conduit means for passing one or more optical fibers from within said enclosure; and

wherein an outer wall of said enclosure is removable to allow access to said optical fibers passing therethrough.

4. An optical fiber sidecar for an optoelectronic converter comprising:

a water-tight and pressure-tight enclosure;

said enclosure having an entrance opening and an exit opening through which a fiber cable containing at least one continuous optical fiber is passed;

said enclosure including a plurality of splice trays for positioning one or more optical fibers within said enclosure such that the minimum bend radius for each optical fiber is not exceeded; and

a conduit separate from said entrance and exit openings for passing one or more optical fibers from within said enclosure to an optoelectronic converter;

said conduit comprising a cylindrical sleeve and sealing means on each sleeve end forming water-tight and pressure-tight seals for said conduit.

5. An optical fiber sidecar according to claim 4 wherein said enclosure and said conduit are shielded against electromagnetic interference leakage.

6. An optical fiber sidecar according to claim 4 wherein said enclosure is fixedly attached to a housing for an optoelectric converter.

7. An optical sidecar according to claim 4 wherein an outer wall of said enclosure is removable to allow access to said optical fibers passing therethrough.

8. An optical fiber sidecar for an optoelectronic converter comprising:

an enclosure having an entrance opening and an exit opening through which a fiber cable containing first and second sets of optical fibers is passed;

said first set of optical fibers including at least one continuous optical fiber that passes through said entrance and exit openings;

said second set of optical fibers including at least one optical fiber that passes through said entrance opening and is separated from said fiber cable within said enclosure;

said enclosure including means for positioning said second set of optical fibers within said enclosure such that the minimum bend radius for each said second optical fiber is not exceeded; and

said enclosure including a conduit separate from said entrance and exit openings;

said conduit having conduit means for passing said second set of optical fibers from within said enclosure to an optoelectronic converter.

9. An optical sidecar for an optoelectronic converter according to claim 8 wherein said enclosure and said conduit means are water-tight and pressure-tight.

10. An optical sidecar for an optoelectronic converter according to claim 8 wherein said enclosure and said conduit means are shielded against electromagnetic interference leakage.

11. An optical sidecar for an optoelectronic converter according to claim 8 wherein said enclosure is fixedly attached to a housing for an optoelectronic converter.

12. An optical sidecar according to claim 8 wherein an outer wall of said enclosure is removable to allow access to said optical fibers passing therethrough.
